这题可不可以想成是Assumption题，对各选项取非看是否削弱...对A取非： NONE of the jays retrieved stored ...

终于明白了！就是文中给出了in the wild的情况（食物匮乏出现retrieve），还讲了C的实验（实验中鸟出现retrieve）--->实验中的鸟一定是处在食物匮乏的情况下。因为如果不是处在食物匮乏的情况下，那么实验中出现的retrieve现象就是随机现象了，因此也就推不出结论了

我感觉应该选A，因为在In the wild 的情况下，只有当傻鸟处在饥荒的情况下才会回去取食物。而这个实验是研究傻鸟到底有没有episodic memory，在傻鸟存食到取食的之间有一段时间让它判断cricket有没有坏“Clayton’s birds switched their preference from crickets to peanuts once the food had been stored for a certain length of time”，所以不可能Throughout the experiment都让它处在饥饿感中。

A是错的吧，第一次取说明没有达到scarcity 所以应该都是取了crickets

首先先复制一段很有道理的话：All Must Be True answer choices must pass theFact Test: The correct answer to a Must Be True question can always be proven by referring to the facts stated in the stimulus. If you find yourself having difficulty prephrasing an answer to a Must Be True question, do not be concerned. The scope of the stimulus—especially if that scope is broad—often helps eliminate one or more of the answer choices. You can often predict the occurrence of Must Be True questions because the stimulus of most Must Be True questions does not contain a conclusion. Correct Answer Types: Paraphrased answers are answers that restate a portion of the stimulus in different terms. When these answers mirror the
stimulus, they are correct. Combination answers result from combining two or more statements in the stimulus.
所以E 选项可以来根据原文中的含义来选择，在野外怎样怎样（IN the wild… ）但在C‘s experiment里，当读到 food  Crickets were stored in one location and peanuts in another. 我就想为啥要在不同的地方呢？鸟会这么做吗？把吃的放在两个地方，于是我想这肯定是人工来做的。并且要让鸟出现food scarcity的时候也是要喂的。所以E选项是对原文含义的一个梳理，或者是一个总结，所以must be true.
而最开始我选的A，用这个理论来想想，其实很简单，不用想太多，这只是一个未提的内容，文中只是说了一些现象，但是并没有提到说 On the first occasion时是怎样的，所以不能说这个到底是不是must be true.
真是比较偷懒的想法啦。但我觉得实战的时候需要快速决定的想法，纠结就好容易错。

我觉得楼主的所有分析都是对的，但是出发点是不是搞错了。问题问的是must be true的是episodic-like memory,而不是episodic memory. 那两个条件也是episodic memory的条件。而现在是在episodic-like memory的前提下。如果是这样的话，符合1）multiple components of a single event这个条件就已经完成了episodic-like memory的这个前提。如果加上了条件2）bond together，就变成了episodic memory了。
所以A是个episodic memory而不是个episodic-like memory.
d说能够retrieve a cricket or a peanut,但是没吃。就满足条件1），而没满足条件2）。所以就符合题干所说的：epsodic-like memory.

一点晚了好几年的拙见。嘿嘿
还请后人继续探讨。

【must be true】＋【逻辑：找前提】
实验证明鸟有episodic-like memory，哪项是必要的？
原文：In the wild, these birds store food for retrieval later during periods of food scarcity.
Crickets were stored in one location and peanuts in another
对照原文“In the wild, these birds store food for retrieval later during periods of food scarcity. ”实验是需要模拟野外的状况的，所以就是控制变量也就是E中的“ fed at levels typical of a time of scarcity.“
A选项本身可能是正确的，但是不是实验的内容或前提，无法“in order for”
