1.[a]of
[b]in
[c]with
[d]within
2.[a]in which
[b]for whom
[c]with which
[d]of whom
1.选[a].该题考查定语从句引导词前介词的选择。定语从句可以由“介词+which/whom”来引导，介词的选择取决于从句动词的搭配关系以及从句本身的意义。本题中which代表前面的one hundred languages,根据句意，其中14种被定为官方语言，这是一种部分与整体的关系，所以关系代词前面的介词要用of.
2.选[d].该题考察非限定性定语从句。观察句子结构及四个选项可以看出这里需要一个“介词+关系代词”的结构引导定语从句，因其先行词为人(20students)，且从句中需一个表范围的词，介词of表示“在一群人当中有一个或几个”
