[問題]2000年5月考古題 文法 Q4

[molecular]

Stars shine because of ____produced by the nuclear reactions taking place within them.
(A) the amount of light and heat is
(B) which the amount of ligh and heat
(C) the amount of light and heat that it is
(D) the amount of light and heat

The answer is : (D)

我想請問的是, 我知道of之後應該是加名詞片語
但是我覺得taking place這個地方是不是應該用which takes place才對呢?
求助善心人士, Thanks

taking place就是which take place減化而來的，
take不加s是因為reactions是複數，
就如同題目中的produced原來是which is procued。
