178. In the last few years, the number of convicted criminals given community service sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have risen dramatically.

(A) sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have

(B) sentences, performing specific jobs that benefit the public while being allowed to remain unconfined, have

(C) sentences, performing specific jobs beneficial to the public while they are allowed to remain unconfined, have

(D) sentences which allow them to remain unconfined in their performing of specific jobs beneficial to the public has

(E) sentences allowing them to remain unconfined while performing specific jobs that benefit the public has（E）

请问红色部分的中心词是criminal吗，given community services 是过去分词作定语吗，若是的话，该句的主语岂不成了罪犯的数目。可我看过以前的讨论，似乎该句的主语为法规，该句的结构究竟该如何划分呢，请大家不要拒绝回答我这个简单问题呀，谢谢了

a of b中心词是a，是number.given community services是修饰criminals（过去分词做定语，就近修饰前面的名词）。这个句子的结构就是：the number has risen dramatically.

of后面的成分convicted criminals限定the number。

补充一下：“a of b的中心词是a”--不是每一例都是的。在the number of B中，核心词是the number 没错，但如果是a number of B,核心词是B，意为“许多的B如何”，而不是“许多如何”
