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 recovering a perishable treat if
D. tends not to bother recovering a perishable treat
E. tends not bothering to recover a perishable treat if
我想选a ,我觉得tend 和 remember 并列也
如果tend和remember并列的话，can tend是说不通的
