        Today, many large corporations stress the importance of diversity on their websites, but current statistics show that the typical manager in America still tends to be white and male. Obviously, (19) [the desire to bring about diversity has not translated into corporate reality.] Why is this? A team of researchers from the University of Basel published (20) [their new study about people’s attitudes towards diversity at work.] They found that people have a wide range of opinions concerning diversity. On the one hand, many see value in diversity, which can contribute a variety of perspectives, encourage new ideas and generate innovative solutions. On the other hand, they assume that it might be difficult to work with someone who has completely different views, speaks a different language, or has a different style of work. The actual value they attribute to diversity depends on the decision-making perspective. Doubts about the practicability of diversity have a greater weight if a person is directly affected. In other words, when a person’s own work group is involved, (21) [they tend to prefer team members who are similar to themselves.] But when people make decisions for others, they typically put together a more diverse team. These findings could help organizations become more diverse. Companies need to pay attention to who makes hiring and team decisions. These decisions should not only be made by those directly affected. People who are not directly involved in the group’s daily work should also take part.

21. What do the findings of the new study show?

解析：A。录音后半部分指出，在涉及到自己的工作团队时，人们往往会选择与自己相似的团队成员（prefer team members who are similar to themselves）。A项与此相符，故为正确答案。

错项排除：录音开头提到许多大公司都在其网站上强调多元化的重要性，但这并不是研究发现的内容，故B项排除。录音中提到多元化的价值取决于决策视角，也就是说是为自己还是为他人做决策，结果是不同的，但并没有说雇主和雇员对于多元化的看法不同，故C项排除。D项利用录音中的Doubts about the practicability of diversity进行干扰，但are gradually disappearing在录音中无依据，故排除D项。
