23. Vaish holds that the rethinking about guilt comes from an awareness that________

23、【答案】[A]an emotion can play opposing roles

【解析】根据题干可知这是一个典型的细节题。根据题干关键信息 “Vaish holds that …awareness that…” 定位到本文的第二段 “There has been a kind of revival or a rethinking…can serve.”此句为题干信息所在句，提示答案将在下文补充： “adding that this revival is…in another”（这种复兴是更大的认识的一部分，即情绪不是二元情感——在一个情境中有利的情绪在另一个情境中可能是有害的）。对比四个选项，只有 A项“an emotion can play opposing roles”（情绪可以起到相反的作用）为正确答案。B项“emotions are socially constructive”（从社会角度讲，情绪具有积极性）在文中没有提及。C项“emotional stability can benefit health”（情绪稳定有益于身体健康）在文中没有提及。D项“emotions are context-independent”（情绪与语境无关）与原文表述相反，故排除。
