I've looked at a number of explanation videos for this concept on TH-cam and this is by FAR the best. Thank you for breaking this down in the way you did. I'm FOREVER grateful and memorizing these two rules for seamless application on the test!
I understand your method as something like this. The first criterion is saying that "under the original rule (OR), the choice rule (CR) must be true," so OR≥CR. The second criterion is saying that "under the choice rule (CR), the original rule (OR) must be true", so CR≥OR. Since OR≥CR and CR≥OR, OR=CR and the considered choice is the the correct choice.
I like this summary. As long as "under the original rule, the choice rule must be true" means under the original rule *combined with* the other rules, the choice rule must be true. And as long as "under the choice rule, the original rule must be true" means under the choice rule *combined with* the other rules, the original rule must be true.
