Scientific Mice

GMAT-ILNM3N

Researchers studied a group of 30 mice to determine if mice develop relationships with each other. The mice were bred, sterilized, and from birth all lived together in an enclosed habitat for three months. At the end of three months, each mouse was separated from the group for a period of three days. At the end of three days, each mouse was then allowed to either rejoin the group or continue to remain in isolation. All 30 of the mice chose to rejoin the group.

Researchers were able to determine that mice do in fact develop relationships with each other. However, critics of the study stated that the mice were all prompted to rejoin the group because of the placement of a food source, and within such a constructed habitat, determinations of relationship were more related to food than the other mice.

How do the parts of this explanation in bold typeface best relate to each other?

A

The first supports the researchers’ conclusion and leads to the second, further developing the researchers' conclusion.

B

The first is an observation within the experiment. The second statement complicates the researchers' conclusions based on the observation.

C

The first is evidence upon which the researchers make their determination yet the second is evidence upon which the researchers will base their next experiment.

D

The first is the conclusion of the experiment and the second refutes the critics' doubt about the scientists' conclusions.

E

The first explains the findings of the experiment’s hypothesis; however, the second directly contradicts the findings by pointing out the only flaw in the experiment.
