Rough【C1】________of their population went as high as five billion and they accounted for around 40 percent of the total indigenous bird population of North America in the early 19th century.
Despite their huge population, passenger pigeons were【C2】________to human intrusion into their nesting territory.

选项
答案
I
解析
空格前为two weeks after the eggs,空格后为逗号,由此可知,此处是after引导的时间状语从句,缺少谓语动词,此处描述过去发生的事情,故应使用一般过去时。由主句the parent pigeons would abandon their offspring,leaving them to take care of themselves(亲鸽会抛弃它们的后代,让它们自己照顾自己) 可知,从句应该说的是旅鸽蛋“孵化”两周后……,故hatched符合语境。
