200. (T-3-Q14)
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

想请教一下大家，这里的“researchers have discovered,” 是作什么成分？这道题的句子结构没看明白

PS：答案为D

插入语吧 can remember和tends 并列俩个分句都是researchers发现的。。个人意见。。LX指正。。
