Question

Of the many opinions expressed to the council members by the various citizens'group present ,( )

was the only opinion that mattered
A their B their one C theirs D they
谁能帮我看一下选哪个答案，希望有解析一下，非常感谢了，

Answer 1

选择C.theirs，首先凭语感其实就能差不多
其次用排除法，their后必须加名词才能充当句子成分，their one说不通，数不一致；they是复数，主谓不一致。只能选C。theirs是名词性物主代词，代their opinion.

可追问，望采纳：）
