各位老师好，有一道关于反义疑问句的阅读理解题想请教老师们：

原文相关内容：

These ants eat all the animals on their way. They can kill and eat elephants, and they can eat wood houses.

Sometimes they can kill people.

问题：

These ants eat elephants, don't they?

A. Yes, they eat.   C. Yes, they eat elephants, people and all the animals.

答案是C。但我认为这道题的答案应该是：Yes, they do. 因为问题只问了吃大象的问题，其他的没有问啊，而且

这道题反义疑问句的回答难道不是Yes, they do.吗？我觉得C无论从内容还是回答的规范来说都不合适。

请各位老师指教，谢谢！
