To determine whether chimpanzees are more likely to delay gratification for

a cooked food reward than they are for a raw food reward, cognition researchers

Felix Warneken and Alexandra Rosati conducted an experiment comparing

chimpanzees' decisions in two situations: a "raw-delay" condition and a

"cooked-delay" condition. In the raw-delay condition, Warneken and Rosati

offered the chimpanzees a choice between receiving a piece of raw food

immediately and waiting for one minute to receive three pieces of raw food; the

chimpanzees chose the larger, delayed reward 60 percent of the time. In the

cooked-delay condition, in which the chimpanzees could receive one piece of raw

food immediately or wait one minute for three pieces of cooked food, they chose

the larger, delayed reward approximately 85 percent of the time.

A.NO CHANGE

B.of whether

C.either

D.for

答案：A

解析：Choice A is the best answer because in this context, the phrasing "a

choice between receiving X and (waiting for) Y" is consistent with the

conventions of standard written English.
