og verbal 分册第二版里第十一题答案是C
虽然其他四个错误明显
但是我觉得C选项的那个they会有指代不明啊，毕竟不能确定是指葡萄牙人还是花生...
求各位大神解答！！！！

Native to South America, peanuts were introduced to Africa by Portuguese explorers early in the sixteenth century and were quickly adopted into Africa’s agriculture, probably because they were so similar to the Bambarra groundnut, a popular indigenous plant.

pronoun ambiguity不是absolute rule，GMAT對這個有一定tolerance
另，雖然根據number，explorers和peanuts都有可能是antecedent，但meaning上antecedent應該是peanuts，而且peanuts是句子的subject-->所以they指代peanuts較優

同意LS，在这种情况下，优先指代主句主语，而且从句子意思上看完全不会造成歧义。

根据逻辑意思来看，先行词就只能是peanuts,因为说explorers被采用到agriculture 里去不是很符合逻辑。曼哈顿语法里有说过，当先行词只有一个符合逻辑意思的时候，就只有那一个可能。所以，不存在不明。
