Psst! Don't forget that rule #2 applies to ALL causes and effects. And to clear up any ambiguity, the fuel gauge glowing, the gravitometer spinning, and the helium tank rattling count as both causes and effects.
I had a different problem with rule #2 - I mentally rephrased it as "multiple causes in conjunction produce no effect" which technically implies an exclusive-or relation when multiple causes have one effect (or vice versa), which makes the riddle unsolvable :(
I had all my letters with the right things I put D as nothing(?) and didn’t think that rule #2 applied to the car malfunctioning but when I found out in the video I quickly figure out which one was correct. I’m giving myself 70/100
@@trevorvergesart The key is in rule 2: No Effect is produced by multiple causes in conjunction. #6 reads "Shortly after the Fuel gauge Glows and the Gravitometer spins, the reactor leaks". **This does not mean that both the Fuel gauge and the Gravitometer need to be both going off simultaneously to cause the leak**, as such a requirement would break the rule. It is possible that they both cause reactor leaks (the same way thrusters B and C both cause the Fuel Gauge to glow), but they cannot require the other to do so. Once rule 2 is understood than the implications of notes 5 and 6 are clear - if the Gravitometer caused reactor leaks, then it would ALWAYS cause them, Fuel Guage be darned. That means that in note 5, the Gravitometer should be causing a reactor leak. Yet the Gravitometer is spinning and no reactor leak in sight. This means that the Gravitometer doesn't cause reactor leaks, so in note 6, the Fuel gauge is responsible. The same concept can be applied to note 5 itself to show that the Helium tank, not the Gravitometer, is responsible for the ignition explosion and the oxygen depletion, since if the Gravitometer was causing them, it would also cause them in note 6. Thus, any thruster that sets off the heilum tank is a no go, since it will cause ignition explosion and oxygen depletion. Also, any thruster that sets off the Fuel Guage is ALSO a no go since it causes reactor leaks. Setting off the Gravitometer is a-ok, though, since we just proved it does nothing.
The fallacy with our answers, mine being the same as OP's, was that we assumed that the gravitometer was the key factor in causing the critical failure, when instead we should have ruled it out because it was the common factor that had no effect on it's own, i.e. we ignored the rule that stated if a cause showed no effect independently, it would cause no effect even when present simultaneously with any other cause.
Ah yes, I turned on only D for the first 2 seconds of the run, then at the last second, turned on E, and, although I hated the gravitometer spinning, got the win.

edit: I realized my mistake and now know what went wrong. Where I got lost was the fact that, i assumed the effects rules only applied to rockets via problems. But it turns out it also applies to the problems via hazards. I feel like this specific riddle was a little bit unclear as it says that he was certain that the failures were causes of chain reactions from the thrusters 1:11 so the fact that when the gravitometer spins & the helium tank rattles, the ignition explodes and the oxygen levels deplete so the 'chain reaction' of the helium tank rattling and the gravitometer spinning creates the catastrophe. Therefore as long as you didn't trigger both of them you'd be fine no? this led me to conclude the opposite of the final answer as both had the gravitometer spinning so as long as i didn't use that no chain reaction would take place and id be safe. so i could activate 'a, b, c, & d'
I found the same answer using the same logic. For me, the notes implied that while activating 1 thruster may trigger 2 different reaction (random exemple : thruster D making the Helium Tank Rattle and the Fuel Gauge glow), the fatal errors where caused by the combination of the different problems (aka the reactor leaks ONLY if you trigger both the Fuel Gauge AND the Gravitometer) So yeah, that one riddle was confusing, especially since there are 5 thrusters and it ask you to use as many as you can, so using 4 of them seemed way more intuitive than only 2
Same, and I believe we are correct in this if the premises is, as said, a chain reaction... instead of using only the spin as they did, I concluded that if "rattle + spin = boom + no-O2" and "glow + spin = leak", then I could not use either the thrusters that cause rattle or glow in conjunction with spin, yet nothing points to them not being used together, so spin would be the one to avoid, hence no E

Took me a while to figure out the answer: D and E. (I would've crashed way before solving it). Good riddle IMO. Rule #2 and rule #3 are important to understand since they state that "No effect is produced by multiple causes in conjuction" and "different causes may separately lead to the same effect" This means that for clue #1 the fuel gauge glow CANNOT be due to BOTH B and C being turned on. Either (Option 1)B makes the glow and C does not, (Option 2)C makes the glow and B does not, or (Option 3) they both make the glow independently. The video clearly shows the last option. Similarly in clue #5 the ignition exploding and oxygen levels depleting CANNOT be due to BOTH the rattle and spin. Either (OP. 1) the rattle causes the explosion and the spin causes depletion, (OP. 2) the rattle causes depletion and the spin causes explosion, (OP. 3) the rattle causes both the explosion + depletion, (OP.4) the spin causes both the explosion + depletion, or (OP.5) they both cause the explosion + depletion independently. It's neither the first two nor the last two options. In clue #6 the gravitometer spins but there is neither an explosion nor an oxygen depletion. So the rattle must be the cause of explosion + depletion. This is fine because rule #4 states "a single cause can lead to multiple effects."

I had an assignment like that in 11th grade math, my answer was the thought process of not pushing the buttons that are involving the part of ABD, ADE, and CDE, my teacher loved it 😊
I got a different answer, I thought the spinning gravitometer in combination with the helium tank/fuel gage caused a different outcome. So as long as the gravitometer does not spin, nothing will go wrong. I deduced that E caused the meter to spin, so A, B, C, D can all be activated.
I made the same mistake. I thought the combination rule only applied to thrusters and not to the effects themselves, hence I was using the same logic as you.
Notice how they worded it in the visual demonstration, “factor” not “thruster”, and the rules also say “cause” not “thruster”. You guys made assumptions, not a good things to do to solve riddles.
I managed to solve this one correctly, but to do so I had to make one critical assumption that wasn't explicitly stated: that the test notes were exhaustive and included any and all symptoms that occurred (e.g. if the fuel gauge isn't mentioned, it definitely didn't glow during that test run). In other words, I had to assume that absence of evidence = evidence of absence, which typically isn't reliably true.
But there is a logic problem, B and C make the thing glow, when on together, but it says, more than one cause, doesn’t give the result. So B and C cannot both be the cause for the glowing
@@Tacholoco You've misread the rules. They say that more than one cause can independently give the same result (x *or* y causes z). What can't happen is for an effect to be triggered by two causes when neither cause alone does it (x *and* y causes z).

It would have been such a cool detail if, when they pressed the buttons, the gravitometer started spinning when the thrusters came on. It would have been such a minor detail, but it would’ve been so cool.
The question statement was a bit a ambiguous, because when you have stated that one engine many be responsible for more than one outcome, then it must be valid to assume that say if engine X,Y give E as effect then set of all effects by X,Y is not necessary equal to {E} [ Which is not true in general]. For example a better statement for observation results is ' when B and C are ON, *only* the fuel gauge glows. ',and so on.
@@flargarbason1740 With all due respect, that's bad advice. If you look at it straight forward in a rigorous way, you get exactly the described problem. You only avoid it by either not looking at it straight forward, but thinking a little bit about how the concrete constraints of the riddle look like, which is thinking more, not less, or by going with some gut feelings about the meaning. The last version might get someone to the right conclusion easily ""by not overthinking it"", but will completely mislead someone else into solving a question that was never asked, making his inherently consistent solutions entirely worthless for the actual riddle. "Don't overthink it" is a vague advice that is usually very wrong and only really applicable to specific cases. I do not believe this is one of them, and even if it was, you didn't have the information to know it based on what Bhaskar Pandey wrote.

@@theangelraziel Yeah I didn't fully understand that application to the final 2 test notes and originally saw it applied only to two different buttons until it was mentioned in the first part of the solution. Immediately paused the video and resolved. Could have been worded better, but it was somewhat explicitly stated so I can't be too miffed.
@@theangelraziel "No effect is caused by two factors in conjunction." This doesn't affect the ABCD answer. In fact, it supports it. According to what's written, pressing E makes the gravitometer spin.
@@clanpsi I know this is a late reply, but I don't control the whims of the TH-cam algorithm. xD What rules out the ABCD answer is the rule that the same cause will always have the same effect. So if the Gravitometer is the cause of all the faults, it would trigger all of them all the time. Not Ignition and Oxygen one time, but the Reactor the second time.
The answer is incorrect. You can press them all except E. The Ignition explodes only if the helium tank rattles AND the gravitometer spins and the reactor leaks only if the fuel gauge glows AND the gravitometer spins. Therefore, you are safe as long as the gravitometer doesn't spins. If you click A B C D it causes 1 and 2 neither of which cause the gravitometer to spin, so you are safe.
Let's appreciate the naming here, giving consistent and unique letters to everything! (buttons A to E, Fuel gauge, Gravitometer, Helium tank, Ignition, Oxygen and Reactor)
The thing i like about those ridles is that they have a story behind.It makes it more interesting than just saying the conditions and the riddle.Sorry,my English sucks, I'm moldovan
event X, Y or Z (ignition exploding, reactor leaking, oxygen depleting) are loss conditions. events 1, 2, 3 are symptoms (fuel gauge glows, helium tank rattles, gravitometer spins). A, B, C, D, E are thrusters. B+C -> 1 A+B+D -> 1+2 C+D+E -> 1+3 A+D+E -> 2+3 2+3 -> X+Z 1+3 -> Y doing all 5 is clearly not possible, since that would trigger all bad things to happen. doing 3 is clearly possible through A+B+D so the question is then: can we do 4? lets try to figure out what side effects the various thrusters have. B+C are involved in making (1) and nothing else, this means that neither of them cause 2 or 3. A+B+D are involved in making 1+2, therefore neither of them cause 3. C+D+E are involved in making 1+3, therefore neither of them cause 2. A+D+E are involved in making 2+3, therefore neither of them cause 1. this leaves only A remaining as being able to produce 2 and only E remaining as being able to produce 3, since 2 and 3 have been produced in our tests, that means at least one thruster does cause that effect and therefore A causes 2 and E causes 3. C+D+E produces 1 (and 3, but that's not important right now), but neither D nor E can produce 1, therefore C produces 1. A+B+D produces 1 (and 2, but that's not important right now), but neither A nor D can produce 1, therefore B produces 1. which gives us our table of causes and effects: 1 2 3 A x o x B o x x C o x x D x x x E x x o and we can see that by using the combination A+B+C+D we get the effects 1+2, which is not known to cause any form of critical failure, although perhaps the testing was incomplete and 1+2 does indeed cause some critical failure, in which case there is no 4-thruster solution since any other 4-thruster combination would involve E and at least 1 of B and C, which would cause a reactor leak. therefore, if there is a 4-thruster solution, it is A+B+C+D. edit: imo the rules were unclear. the animation showing factor and effect interaction only showed pressing of buttons, that made me think the only thing that applied to was the activation of thrusters.
"When thrusters A, B, and D are on...." I read that to mean all 3 must be on at the same time for the effect to happen, not that each independently triggers the reaction. So I came up with the wrong answer due to grammar. :(
Dear Ted ed ; Here we need to avoid two case; First case is of ignition exploding and oxygen depleting which is triggered by the helium tank rattle and gravitometer spinning the second case is of reactor leaking which triggered by the fuel gas glowing and gravitometer spinning Now; (as I see it as per my analogy) A=helium tank rattle B,C=fuel tank glow D,E=gravitometer Maximum no of thrusters we could turn in avoiding the aforementioned two case ( of failure) are A B & C (i.e.3) {as combination of these 3 thrusters is leading to any failure} Please help me out I am regular follower of your puzzles . Thanks a lot!!
Rule #2 may be technically ambiguous. When it says "no effect is produced by multiple causes in conjunction" I rephrased it as "multiple causes in conjunction yield _zero_ effect" (i.e. their effects actively _cancel out,_ exclusive-or style) which makes the problem basically unsolvable :(
No side gang: *"Has a choice to steal all of your uncle's invention by robbing his house in the night"* Also no side gang: *"Kidnaps your uncle then tells you to race with them with a 50 50 chance of failing to get all of your uncle's invention"* Me: Accurate
So buttons ABCDE are the factors for fuel gauge to glow, helium tank to rattle and gravitometer to spin, which become the factors for the ignition to explode, oxygen levels to deplete, and reactor to leak. So the effect of a factor is also a factor of an effect.
Somebody explain this thing to me because I got a + b + c + d for my solution. I assumed a factor was a button, a cause was one of the events that can cause a failure in conjunction with another specific cause (fuel gauge glows, gravitometer spins, helium tank rattles), and the effect is the failure (exploding ignition and reactor leaking). so I got a + b + c + d because rule 5 negates rules 4 so we can ignore that one. b and c cause the fuel gauge to glow (that's fine), a + b + d cause the fuel gauge to glow and the helium tanks to rattle (doesn't cause a failure per the rules so this is fine as well). 4 > 2 therefore the best chance to make the jump is having 4 thrusters on (a + b + c + d) not 2 (d + e). The riddle isn't saying that none of the activated thrusters can cause any of the instruments to malfunction, it seems like if that is the case, rule 5 and 6 are not necessary and it should read that no causes can be present. Which buttons when pressed cause no effects? Please point out the fault in my logic here. Driver here most certainly fell in the ditch and blew up into a thousand pieces with that solution.
I've got the same answer. B+C is safe, A+b+c doesn't cause a malfunction and d seems to cause nothing at all, which is technically not against the rules. Either this puzzled is extremely bad formulated (which is a common issue in ted ed series) or their answer is wrong Edit: nvm, pinned comment explains that gauge, tank and ignition should also be counted as causes, but the wording in the video makes little sense then
Hey! I think I may have found a better answer? Since you only lose if the Ignition explodes, Oxygen Tank depletes, or Reactor leaks, we should be trying to find a condition where none of those things happen. Based on #5 and #6, we can only really lose if the Gravitometer spins alongside either of the other errors, so as long as the gravitometer doesnt spin, we survive. F and H? Those two things in conjunction dont seem to cause a loss state, so based on #2 and #1, we should be able to turn on A, B, C and D without dying, as, it seems, the only way to trigger the Gravitometer to spin and create one of the loss states is by using switch E. Flip the other four on and you win!
FYI: Thruster E makes the gravitometer spin, as it was activated in runs 3 and 4 when it did, and all the other thrusters have at least one activation in runs 1 and 3 where it didn't.
Psst! Don't forget that rule #2 applies to ALL causes and effects. And to clear up any ambiguity, the fuel gauge glowing, the gravitometer spinning, and the helium tank rattling count as both causes and effects.
I had a different problem with rule #2 - I mentally rephrased it as "multiple causes in conjunction produce no effect" which technically implies an exclusive-or relation when multiple causes have one effect (or vice versa), which makes the riddle unsolvable :(

Why wouldn't the answer be ABCD?
@@trevorvergesart The key is in rule 2: No Effect is produced by multiple causes in conjunction.
#6 reads "Shortly after the Fuel gauge Glows and the Gravitometer spins, the reactor leaks". **This does not mean that both the Fuel gauge and the Gravitometer need to be both going off simultaneously to cause the leak**, as such a requirement would break the rule. It is possible that they both cause reactor leaks (the same way thrusters B and C both cause the Fuel Gauge to glow), but they cannot require the other to do so.
Once rule 2 is understood than the implications of notes 5 and 6 are clear -
if the Gravitometer caused reactor leaks, then it would ALWAYS cause them, Fuel Guage be darned. That means that in note 5, the Gravitometer should be causing a reactor leak. Yet the Gravitometer is spinning and no reactor leak in sight. This means that the Gravitometer doesn't cause reactor leaks, so in note 6, the Fuel gauge is responsible. The same concept can be applied to note 5 itself to show that the Helium tank, not the Gravitometer, is responsible for the ignition explosion and the oxygen depletion, since if the Gravitometer was causing them, it would also cause them in note 6.
Thus, any thruster that sets off the heilum tank is a no go, since it will cause ignition explosion and oxygen depletion. Also, any thruster that sets off the Fuel Guage is ALSO a no go since it causes reactor leaks. Setting off the Gravitometer is a-ok, though, since we just proved it does nothing.

Good riddle IMO.
Rule #2 and rule #3 are important to understand since they state that "No effect is produced by multiple causes in conjuction" and "different causes may separately lead to the same effect"
This means that for clue #1 the fuel gauge glow CANNOT be due to BOTH B and C being turned on. Either (Option 1)B makes the glow and C does not, (Option 2)C makes the glow and B does not, or (Option 3) they both make the glow independently. The video clearly shows the last option.
Similarly in clue #5 the ignition exploding and oxygen levels depleting CANNOT be due to BOTH the rattle and spin. Either (OP. 1) the rattle causes the explosion and the spin causes depletion, (OP. 2) the rattle causes depletion and the spin causes explosion, (OP. 3) the rattle causes both the explosion + depletion, (OP.4) the spin causes both the explosion + depletion, or (OP.5) they both cause the explosion + depletion independently. It's neither the first two nor the last two options. In clue #6 the gravitometer spins but there is neither an explosion nor an oxygen depletion. So the rattle must be the cause of explosion + depletion.
This is fine because rule #4 states "a single cause can lead to multiple effects."

I had an assignment like that in 11th grade math, my answer was the thought process of not pushing the buttons that are involving the part of ABD, ADE, and CDE, my teacher loved it 😊
I got a different answer, I thought the spinning gravitometer in combination with the helium tank/fuel gage caused a different outcome. So as long as the gravitometer does not spin, nothing will go wrong. I deduced that E caused the meter to spin, so A, B, C, D can all be activated.
But no effect is caused by combination of the two reasons. They said it in the video!
Иван Логинов
Yeah, rule number whatever
I made the same mistake. I thought the combination rule only applied to thrusters and not to the effects themselves, hence I was using the same logic as you.
Notice how they worded it in the visual demonstration, “factor” not “thruster”, and the rules also say “cause” not “thruster”. You guys made assumptions, not a good things to do to solve riddles.
spent too long solving the riddle, already fell in the ravine
I managed to solve this one correctly, but to do so I had to make one critical assumption that wasn't explicitly stated: that the test notes were exhaustive and included any and all symptoms that occurred (e.g. if the fuel gauge isn't mentioned, it definitely didn't glow during that test run).
In other words, I had to assume that absence of evidence = evidence of absence, which typically isn't reliably true.
But there is a logic problem, B and C make the thing glow, when on together, but it says, more than one cause, doesn’t give the result. So B and C cannot both be the cause for the glowing
@@Tacholoco You've misread the rules. They say that more than one cause can independently give the same result (x *or* y causes z). What can't happen is for an effect to be triggered by two causes when neither cause alone does it (x *and* y causes z).

It would have been such a cool detail if, when they pressed the buttons, the gravitometer started spinning when the thrusters came on. It would have been such a minor detail, but it would’ve been so cool.
You Can Make This Combination:
A B C D
How? Beacause E Is The Culprit Of The Gravitometer Spinning

The question statement was a bit a ambiguous, because when you have stated that one engine many be responsible for more than one outcome, then it must be valid to assume that say if engine X,Y give E as effect then set of all effects by X,Y is not necessary equal to {E} [ Which is not true in general]. For example a better statement for observation results is
' when B and C are ON, *only* the fuel gauge glows. ',and so on.
yes, it took me some time to realize they must have wanted the viewer to assume this meaning and finally have a solvable problem.
@@flargarbason1740 With all due respect, that's bad advice. If you look at it straight forward in a rigorous way, you get exactly the described problem. You only avoid it by either not looking at it straight forward, but thinking a little bit about how the concrete constraints of the riddle look like, which is thinking more, not less, or by going with some gut feelings about the meaning. The last version might get someone to the right conclusion easily ""by not overthinking it"", but will completely mislead someone else into solving a question that was never asked, making his inherently consistent solutions entirely worthless for the actual riddle.
"Don't overthink it" is a vague advice that is usually very wrong and only really applicable to specific cases. I do not believe this is one of them, and even if it was, you didn't have the information to know it based on what Bhaskar Pandey wrote. I know you're trying to help and I'm actually sorry if I sounded harsh, but as you probably expect, I've given similar cases of advice a lot of thought in the past, and answering to this sort of with the thought of a bigger problem in mind.

The ravine jump is a legal move (it’s a death race, pretty sure there are no rules) it’s just near impossible and suicidal so no one ever tries it
Everytime I think I'm useless, I remember the self-cleaning vaccum cleaner.
Slightly confusing as I thought all of the things had to be activated to cause the disturbance. (In that case, I think the answer is ABCD)
I thought so too, but later realized this is covered by 2. No effect is produced by multiple causes in conjunction.
@@theangelraziel Yeah I didn't fully understand that application to the final 2 test notes and originally saw it applied only to two different buttons until it was mentioned in the first part of the solution. Immediately paused the video and resolved. Could have been worded better, but it was somewhat explicitly stated so I can't be too miffed.
@@theangelraziel "No effect is caused by two factors in conjunction." This doesn't affect the ABCD answer. In fact, it supports it. According to what's written, pressing E makes the gravitometer spin.
@@clanpsi I know this is a late reply, but I don't control the whims of the TH-cam algorithm. xD
What rules out the ABCD answer is the rule that the same cause will always have the same effect. So if the Gravitometer is the cause of all the faults, it would trigger all of them all the time. Not Ignition and Oxygen one time, but the Reactor the second time.
@@clanpsi The gravitometer can’t cause one effect one time and another effect another time
The answer is incorrect. You can press them all except E.
The Ignition explodes only if the helium tank rattles AND the gravitometer spins and the reactor leaks only if the fuel gauge glows AND the gravitometer spins. Therefore, you are safe as long as the gravitometer doesn't spins.
If you click A B C D it causes 1 and 2 neither of which cause the gravitometer to spin, so you are safe.
There's no AND, at 1:23 they say "no effect is caused by 2 factors together"

0:30 Heh, so many silly inventions. Though I think the hatbrella is actually a thing, I could swear I saw someone wearing one in a movie once.
I had it perfectly backwards, I forgot that the rule of two things causing one outcome also applied to the catastrophic failures
The thing i like about those ridles is that they have a story behind.It makes it more interesting than just saying the conditions and the riddle.Sorry,my English sucks, I'm moldovan
I feel the answer should be A, B, C and D turned on. I don't agree that gravitometer is not a factor of malfunction.
Keep in mind that the gravitometer also counts as a cause so rule 5 applies.
Yeah I didn't realise that effects of the buttons had to follow the same rules as the thruster buttons as well
event X, Y or Z (ignition exploding, reactor leaking, oxygen depleting) are loss conditions.
events 1, 2, 3 are symptoms (fuel gauge glows, helium tank rattles, gravitometer spins).
A, B, C, D, E are thrusters.
B+C -> 1
A+B+D -> 1+2
C+D+E -> 1+3
A+D+E -> 2+3
2+3 -> X+Z
1+3 -> Y
doing all 5 is clearly not possible, since that would trigger all bad things to happen.
doing 3 is clearly possible through A+B+D
so the question is then: can we do 4?
lets try to figure out what side effects the various thrusters have.
B+C are involved in making (1) and nothing else, this means that neither of them cause 2 or 3.
A+B+D are involved in making 1+2, therefore neither of them cause 3.
C+D+E are involved in making 1+3, therefore neither of them cause 2.
A+D+E are involved in making 2+3, therefore neither of them cause 1.
this leaves only A remaining as being able to produce 2 and only E remaining as being able to produce 3, since 2 and 3 have been produced in our tests, that means at least one thruster does cause that effect and therefore A causes 2 and E causes 3.
C+D+E produces 1 (and 3, but that's not important right now), but neither D nor E can produce 1, therefore C produces 1.
A+B+D produces 1 (and 2, but that's not important right now), but neither A nor D can produce 1, therefore B produces 1.
which gives us our table of causes and effects:
1 2 3
A x o x
B o x x
C o x x
D x x x
E x x o
and we can see that by using the combination A+B+C+D we get the effects 1+2, which is not known to cause any form of critical failure, although perhaps the testing was incomplete and 1+2 does indeed cause some critical failure, in which case there is no 4-thruster solution since any other 4-thruster combination would involve E and at least 1 of B and C, which would cause a reactor leak.
therefore, if there is a 4-thruster solution, it is A+B+C+D.
edit:
imo the rules were unclear. the animation showing factor and effect interaction only showed pressing of buttons, that made me think the only thing that applied to was the activation of thrusters.

"When thrusters A, B, and D are on...." I read that to mean all 3 must be on at the same time for the effect to happen, not that each independently triggers the reaction. So I came up with the wrong answer due to grammar. :(
You also must have missed that they said no effect is caused by multiple factors in conjunction
Dear Ted ed ;
Here we need to avoid two case;
First case is of ignition exploding and oxygen depleting which is triggered by the helium tank rattle and gravitometer spinning
the second case is of reactor leaking which triggered by the fuel gas glowing and gravitometer spinning
Now; (as I see it as per my analogy)
A=helium tank rattle
B,C=fuel tank glow
D,E=gravitometer
Maximum no of thrusters we could turn in avoiding the aforementioned two case ( of failure) are A B & C (i.e.3) {as combination of these 3 thrusters is leading to any failure}
Please help me out I am regular follower of your puzzles .
Thanks a lot!!
i know i won't be able to solve this so i'll just enjoy the animation
Can we just appreciate the fact that all the letters are A B C D E, then F for Fuel Tank, G for Gravitometer, and H for Helium Tank.

Rule #2 may be technically ambiguous. When it says "no effect is produced by multiple causes in conjunction" I rephrased it as "multiple causes in conjunction yield _zero_ effect" (i.e. their effects actively _cancel out,_ exclusive-or style) which makes the problem basically unsolvable :(

So buttons ABCDE are the factors for fuel gauge to glow, helium tank to rattle and gravitometer to spin, which become the factors for the ignition to explode, oxygen levels to deplete, and reactor to leak. So the effect of a factor is also a factor of an effect.
5:07 lowkey thought this was about to be a raid shadow legends ad
Somebody explain this thing to me because I got a + b + c + d for my solution.
I assumed a factor was a button, a cause was one of the events that can cause a failure in conjunction with another specific cause (fuel gauge glows, gravitometer spins, helium tank rattles), and the effect is the failure (exploding ignition and reactor leaking). so I got a + b + c + d because rule 5 negates rules 4 so we can ignore that one. b and c cause the fuel gauge to glow (that's fine), a + b + d cause the fuel gauge to glow and the helium tanks to rattle (doesn't cause a failure per the rules so this is fine as well). 4 > 2 therefore the best chance to make the jump is having 4 thrusters on (a + b + c + d) not 2 (d + e). The riddle isn't saying that none of the activated thrusters can cause any of the instruments to malfunction, it seems like if that is the case, rule 5 and 6 are not necessary and it should read that no causes can be present. Which buttons when pressed cause no effects?
Please point out the fault in my logic here. Driver here most certainly fell in the ditch and blew up into a thousand pieces with that solution.
I've got the same answer. B+C is safe, A+b+c doesn't cause a malfunction and d seems to cause nothing at all, which is technically not against the rules. Either this puzzled is extremely bad formulated (which is a common issue in ted ed series) or their answer is wrong
Edit: nvm, pinned comment explains that gauge, tank and ignition should also be counted as causes, but the wording in the video makes little sense then
The sponsor at the end has a RWBY reference
Hey! I think I may have found a better answer? Since you only lose if the Ignition explodes, Oxygen Tank depletes, or Reactor leaks, we should be trying to find a condition where none of those things happen. Based on #5 and #6, we can only really lose if the Gravitometer spins alongside either of the other errors, so as long as the gravitometer doesnt spin, we survive. F and H? Those two things in conjunction dont seem to cause a loss state, so based on #2 and #1, we should be able to turn on A, B, C and D without dying, as, it seems, the only way to trigger the Gravitometer to spin and create one of the loss states is by using switch E. Flip the other four on and you win!
