问题 According to the woman, what happened 200 to 500 million years ago?
选项 A、Some sea creatures developed vertebrae.
B、The first giant squid was captured.
C、Some sea creatures shed their shells.
D、Sea life became more intelligent.
答案C
解析 细节复现题。本题的难度相对较低，因为对话中出现数字部分较少，很容易锁定相关答案的出处。原话的意思是“他们在2亿至5亿年之前的这段时间通过脱掉外壳而幸存了下来。”正确选项C虽用some sea creatures替代了they，但没有改变原意。
