Respectfully, Question: #26: If emphasizing "where" he works -- answer B. If emphasizing "for whom" he works -- answer C. #29: I believe answer B would never be used. Answer A would be regarded as correct.
Excellent question; let me try. Generally, when referring to a broad or semi-skilled activity, we tend to use "at." For example: He's good at carpentry, or soccer, or painting, or cooking, etc. And when referring to a HIGHER level of skill or proficiency, then tend to say, for example: skilled in nursing, or skilled in aircraft design. Even as a native speaker, it's not an easy distinction to make. Perhaps the test designer will provide a clearer explanation.
