[讨论]再问！T3-14，关于treat如何能被store的问题！

A scrub jay can remember when it cached a particular piece of food in a particular place, researchers have discovered, and tend not to bother to recover a perishable treat if stored long enough to have rotted.

A. tend not to bother to recover a perishable treat if

B. they tend not to bother recovering a perishable treat

C. tending not to bother to recover a perishable treat it

D. tends not to bother recovering a perishable treat

E. tends not bothering to recover a perishable treat it

正确答案是D

前辈NN们已经给出了详细的解答，我对于答案没有异议，只是关于最后半句话stored long enough to have rotted，我觉得它省略了which was，应该是a perishable treat （which was）stored long enough to have rotted做后置定语修饰treat的。但是实在是想不明白，明明这半句话应该是修饰食物的，意思为食物被保存长时间以至腐烂，但是修饰treat究竟是什么意思？

请指教！不知道是不是我的英语实在是太差了

我，我，我，孤陋寡闻了！谢谢！
