GWD-12-Q5 episodic memory 题

请教GWD12-Q5
GWD-12-Q4 to Q7:
The term “episodic memory” was introduced by Tulving to refer to what he considered a uniquely human capacity—the ability to recollect specific past events, to travel back into the past in one’s own mind—as distinct from the capacity simply to use information acquired through past experiences.Subsequently, Clayton et al. developed criteria to test for episodic memory in animals.According to these criteria, episodic memories are not of individual bits of information; they involve multiple components of a single event “bound” together.Clayton sought to examine evidence of scrub jays’ accurate memory of “what,” “where,” and “when” information and their binding of this information.In the wild, these birds store food for retrieval later during periods of food scarcity.Clayton’s experiment required jays to remember the type, location, and freshness of stored food based on a unique learning event.Crickets were stored in one location and peanuts in another.Jays prefer crickets, but crickets degrade more quickly.Clayton’s birds switched their preference from crickets to peanuts once the food had been stored for a certain length of time, showing that they retain information about the what, the where, and the when.Such experiments cannot, however, reveal whether the birds were reexperiencing the past when retrieving the information.Clayton acknowledged this by using the term “episodic-like” memory.

Q5:
According to the passage, Clayton’s experiment depended on the fact that scrub jays

A.recall “when” and “where” information more distinctly than “what” information

B.are not able to retain information about a single past event for an indefinitely long period of time

C.choose peanuts over crickets when the crickets have been stored for a long period of time

D.choose crickets over peanuts whenever both are available

E.prefer peanuts that have been stored for a short period to crickets that have been stored for a short period

为什么D不对呢？C不是实验结果吗？depended on the fact 不应该是说实验的前提之类的吗？ Clayton的实验是基于SJ喜欢吃crickets胜过peanuts这个事实，所以不是应该选D吗？

同问，刚刚做了这套gwd，我的想法和ＬＺ完全一样

看了很多贴，我觉得答案应该就是Ｃ，ＬＺ的疑问应该是完全正确的

但是这个实验结果本身就是个事实啊，而且文中并没有说无论在什么情况下那个鸟都会选择peanuts而不是crikets,并且原文的意思是为了突显这个鸟的这种能力——知道when,where,what,而变质的crikets鸟是不会选择的，因此C突显了这个鸟的这种能力（并且原文的实验结果也确实如此），而D的话，我个人觉得它什么也证明不了啊，如果D本身就成立的话，那么这个鸟的能力在这个试验中就不能被证明出来，没有任何意义啊。

我也觉得C....

depend on是啥意思啊 我理解是实验的前提 所以觉得D 是对的啊，这么久了 ，有小伙伴来解释一下这题么？
