prep2012 pack1 里的一道SC题 大家来讨论~~

man855112

Narwhals can be called whales of ice: in icy channels, pouds and ice-shielded bays they seek sanctuary from killer whales, their chief predator, and （开始划线了）their annual migrations following (画线结束) the seasnal rhythm of advancing and retreating ice.
A. their annual migrations following
B. their annual migrations which follow
C. their annual migrations follow
D. whose annual migrations following
E. whose annual migrations follow
答案是C。
可是我觉得their指代不清啊，可能指的Narwhals, 也可能是killer whales

麻烦各位大牛牛啦~

同意ls。
一句話中相同pronoun指代的內容應該是一致的，GMAT不會允許相同pronoun

指示不同antecedent的情況出現。

另，pronoun的指代還有一個subject最優的選擇，在符合meaning和

parallelism原則的前提下，subject優先。
因而they指代的是narwhals。

their和前文they的指代要一致，所以没有歧义

saintaa

我刚做完这题
their不可能指代killer whales，因为要是如此的话their前面的逗号就多余

了因为都是修饰 killer whales。
所以their只能指代Narwhals

they seek中they指什么后面的their就指什么。
