        Communication can essentially be divided into two categories: the written and the spoken. How the balance is struck between these two forms of communication—the point at which one needs to be exchanged for another—really depends on individual cultures. (22) [Understanding when it’s appropriate to exchange one form for another can be a major key to success in international business.] Many cultures place a much greater value on the spoken word than the American working culture does. (23) [In parts of the Middle East, you’ll find spoken word agreements are seen as seriously binding.] A person’s word is linked to their honor, so verbal agreements are seen as important, whereas written contracts are taken as memos of understanding. (24) [Western working culture tends to place a high value on the written word, and this reaches its highest level of intensity when it comes to contracts.] In the US, France and Germany, written contracts tend to be seen as something that must be strictly carried out. By contrast, other cultures may not see written contrasts as quite so binding. It can prove a challenge to Western businesses if your business partner wants to renegotiate terms that you thought were already agreed on. For example, (25) [a Japanese firm may have signed a contract, but they may not feel bound by every detail of it]—particularly if circumstances later change. Such differences in value that different working cultures place on the written word tend to cause many problems when it comes to business relationships.

24. What do we learn about the Western working culture?

解析：B。录音后半部分提到，西方的工作文化往往高度重视书面文字（place a high value on the written word），而书面合同（contracts）最能体现这种重视程度。B项与此内容相符，故为正确答案。

错项排除：A项中的evolution和D项中的has seen a decline在录音中无依据，故排除这两项。录音中只提到了一些西方国家认为书面合同必须严格依照执行，并没有说不可更改，C项过度引申，故错误。
