[問題] OG-CR-119
119.
Adult female rats who have never before encountered rat pups
will start to show maternal behaviors after being confined with a
pup for about seven days. This period can be considerably shortened
by disabling the female’s sense of smell or by removing the scent-producing
glands of the pup.
Which of the following hypotheses best explains the contrast described above?
(A) The sense of smell in adult female rats is more acute than that in rat
pups.
(B) The amount of scent produced by rat pups increases when they are in the
presence of a female rat that did not bear them.
(C) Female rats that have given birth are more affected by olfactory cues
than are female rats that have never given birth.
(D) A female rat that has given birth shows maternal behavior toward rat pups
that she did not bear more quickly than does a female rat that has never
given birth.
(E) The development of a female rat’s maternal interest in a rat pup that
she did not bear is inhibited by the odor of the pup.
答案是E
