哪位能帮忙给个结论?大家观点在A/B/E之间。 B All the crickets were retrieved before any of the peanuts were. 和原文中"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. "对应。 E Throughout the experiment the jays were fed at levels typical of a time of scarcity. 和原文In the wild, these birds store food for retrieval later during periods of food scarcity.对应 题干说In order for Clayton’s experiment to show that scrub jays have episodic-like memory, which of the following must be true in the experiment?似乎B和“show that scrub jays have episodic-like memory”更密切。因此倾向B而不是E. 4,5楼选A听起来也有道理。
