### HideShow timer Statistics

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.

why does the odor INHIBITS the interest? this passage reads: it is the odor that STIMULATES the interest...

E.

We need something to connect the two statements above. This connection preferably needs to be explained by an odor given off by the pups. This odor or scent has something to do with why the females do not show maternal behavior for at least seven days.

The author never says that odor stimulates the interest...may be the interest was developed by something else(cute rats may be)...but this interest is affected by the odor in an adverse manner.

you are mentally filling in the wrong gaps for this question without realizing it. The test takers employ psychologists and all sorts of PhD's just for this reason. nowhere did it say odor stimulates interest.

yes, common sense and experience tells us the odor stimulates interest if the rat pup is the actual offspring of the mommy rat. your brain filled in this gap for you, which is why you got it wrong. The question was designed just for this purpose.

the stimulus tells us that odor inhibits maternal instincts if it isn't the rats actual child. over time, a rat will take care offspring that isn't hers. take the odor or the ability to smell away, and it will do it quicker. which is why E is the answer.

This question took me a lot of time for review. So I provide my reasoning here for someone who stuck with brain.

Premise: female rates encountered pups --> trigger maternal behaviors after 7 days
Condition: disable sense or removing glands --> period of triggering will be shortened (less than 7 days)

(E) provide us this connection: removed odor --> trigger maternal interest

does anyone think that "the period" stands for "seven days", like me ?

when I read this question, I am totally mess because I cannot understand the logic of the prompt , if shorten "seven days", then damage the link between smell and odor.

while E states that no odor, no maternal behavior.

what a poor verbal
