GWD-12-Q4 to Q7:

      The term “episodic memory” was

       introduced by Tulving to refer to what he

       considered a uniquely human capacity—

Line
                the ability to recollect specific past events,

  (5)      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

 (10)      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

 (15)      examine evidence of scrub jays’ accurate

memory of “what,” “where,” and “when”

information and their binding of this infor-

mation.  In the wild, these birds store food

for retrieval later during periods of food

 (20)      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

 (25)      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

 (30)      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

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

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

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

4. choose crickets over peanuts whenever both are available

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

这题我选C,是根据26行黄底的这句话，但答案给的是D,我也看到有些人说答案是C。

请问：1、答案是C or D?

          2、D我觉得都有道理，因为原文说Jays prefer crickets,所以如何区分选C还是D呢？

谢谢！
