Rhetorical construction +Agreement

This sentence is correct and concise．They clearly refers to property values，and whose refers to homeowners．

A  Correct．The relationship between nouns and pronouns is correct in this sentence；the

 expression is concise and clear．

B  Can potentially is redundant；in that there is wordy, awkward，and ambiguous．

C  Their appears to refer to they(property values) rather than to homeowners．

D  It does not agree with property values；in that their is wordy and awkward．

E  It does not agree with property values；can potentially is redundant．

The correct answer is A．

they難道不能指代some large investors嗎?如何才算是指代清楚?請指教

可是D and E有更明顯的錯誤 - it沒有指代的對象.
在A, B and C當中, 有都有they, 所以都有指代問題.
可是obviously, 一定有一個是對的.
在這情況下, 只能choose比較好的A.
個人意見: 用"指代不清"來排除choice有點hard...因為很多人都有不同的definition, 可是還沒有一套是100% works for GMAT.

oh...忘記說, 在while/although/even though的從句主語一般都是主句中的主語.
所以妳會frequently見到while/although/even though的主語跟"to be"被omitted...
