这道题用pronoun就可以把a b c d 全部排除。

A. moose's long legs enable it to move quickly through the wood, stepping easily over downed trees, but predators pursuing it must leap or go around them. (it 前面没有单数名词，所有格moose's不是noun,不能用it指代。只有plural 的legs，与it单复数不一致)
B. moose's long legs enable it to move quickly through the wood, stepping easily over downed trees while predators pursuing them must leap or go around.（同上）
C. moose's long legs enable it to move quickly through the wood and to step easily over downed trees, but predators pursuing them must leap over or go around them.（同上）

D. it may be possible for company managers to determine how much effort should be dedicated to each of these products in order to meet the company’s short and long term goals

E. managers at a company can determine how much effort ought to be dedicated to each of these products in order to meet the company’s goals in both the short and long term


D，E的these前面没有proper antecedent，首先排除。
A，B，C中的its是指代company‘s 的。如果it 指代了某样东西，就不能再指代其他东西了，所以A，C也被排除了。
