I can’t say which type of tea tastes better. It’s just a(n) of personal preference.

A. affair

B. matter

C. variety

D. problem

答案：

A. affair

(答案→)B. matter

C. variety

D. problem

解析：

试题分析:考查名词用法。A事务；B事情，物质；C种类；D问题。固定短语：a matter of “。。。的问题”，比如“a matter of time； a matter of money”等，所以答案选B。句意：我说不出哪种茶尝起来更好。那只是个人喜好的问题。
