,7) The following experiment is used for the following question.
A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two
distinct times of the year: early in spring when the oak trees are flowering and in midsummer
when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look
like oak flowers, but caterpillars that hatch in summer feed on oak leaves and look like oak
twigs.
How does the same population of moths produce such different-looking caterpillars on the same
trees? To answer this question, the biologist caught many female moths from the same
population and collected their eggs. He put at least one egg from each female into eight identical
cups. The eggs hatched, and at least two larvae from each female were maintained in one of the
four temperature and light conditions listed below.
Temperature Day Length
Springlike Springlike
Springlike Summerlike
Summerlike springlike
Summerlike summerlike
In each of the four environments, one of the caterpillars was fed oak flowers, the other oak
leaves. Thus, there were a total of eight treatment groups (4 environments × 2 diets).
Which one of the following is not a plausible hypothesis that can be tested in this experiment?
A) The longer day lengths of summer trigger the development of twig-like caterpillars.
B) The cooler temperatures of spring trigger the development of flowerlike caterpillars.
C) Differences in air pressure, due to differences in elevation, trigger the development of
different types of caterpillars.
D) Differences in diet trigger the development of different types of caterpillars.

caterpillars that were raised on oak leaves looked like twigs. These results support which of the
