正确答案:
B:which can roar by causing their hyoid bones to vibrate, domestic cats
(A)这个选择不正确,因为它重复了原始句子。
(B)正确。这个选择通过用“can roar”替换“can be roaring”来纠正原句中的动词问题。这种选择通过使用复数所有格代词“他们的”代替“它”来纠正代词问题。
(C)这种选择错误地使用“who”而不是“which”来指代狮子和老虎。在GMAT上,代名词“who”是为人类保留的;动物和东西用“which”来指代。这个答案选择的另一个错误是包含了“不同”的冗余词。
(D)这种选择使得使用单数所有格代词(“它的”)来指代复数先行词(“狮子和老虎”)是错误的。
(E)这种答案选择不合逻辑地使得狮子和老虎的舌骨似乎振动,从而产生咆哮的声音,而不管狮子或老虎是否真的想要咆哮。使用单一的“咆哮”也是不合适的,因为它似乎表明许多狮子和老虎集体只发出一声咆哮。
