P

50. What is one of the benefits of indifferent relationships?
- A. They provide fun at Work.
- B. They help control emotions.
- C. They help resolve differences.
- D. They improve Work efficiency.
答案：D
答案句：As noted above, indifferent relationships may not always be the most helpful approach in resolving some of the issues that pop up at work. But there are nonetheless several empirically proven benefits. One of those is efficiency. Less time chatting and socializing means more time working and churning (产出).
参考译文：如上所述，冷漠关系可能并不总是解决工作中出现的一些问题的最有帮助的方法。但尽管如此，还是有几个经过实证证明的好处。其中之一是效率。减少聊天和社交的时间意味着有更多的时间工作和产出。
定位线索：题干“benefits of indifferent relationships”→答案句“several empirically proven benefits. One of those is efficiency”；文中“efficiency”对应选项D“improve Work efficiency”。
解析：题干问冷漠关系的好处之一，答案句明确指出“several empirically proven benefits. One of those is efficiency”，并解释“Less time chatting and socializing means more time working”，直接对应选项D“improve Work efficiency”。选项A“provide fun”与原文“None of that might be as fun”矛盾；选项B“help control emotions”原文未提及；选项C“help resolve differences”原文说“may not always be the most helpful approach in resolving some of the issues”，并非其好处。
