Scientists studying climate change have found that one of the overall effects of global warming is not only a higher planetary temperature, but also a universal change in seasons, specifically earlier springs and later autumns. Though some argue that this is an advantage because it presents a longer summer growing season, others fear that too many animal species will be unable to adapt and will become extinct.
Which of the following is the best piece of evidence to support the conclusion that a longer growing season will hasten the extinction of some animal species?
A. Squirrel and chipmunk species are unable either to consume or to store all the nuts and berries produced during a longer growing season.
B. Fungus species typically produce spores only once a year and are unable to produce enough spores to release spores again before the end of a longer growing season.
C. Butterfly species that respond quickly to changes in temperature hatch caterpillars and undergo metamorphosis into butterflies earlier, flying away before bird species that feed exclusively on them have hatched their young.
D. Salmon species that rely on changes in temperature to signal the start of annual migrations leave their freshwater birthplaces earlier, before they have fed sufficiently on freshwater insects to reduce their number.\
E. Reptile species that hibernate during winter months must emerge from hibernation sooner and spend a longer time searching for food before mating in mid-summer.

ANALYZE THE STIMULUS:
Fact: Scientists studying climate change have found that one of the overall effects of global warming is not only a higher planetary temperature, but also a universal change in seasons, specifically earlier springs and later autumns.
Conclusion: Though some argue that this is an advantage because it presents a longer summer growing season, others fear that too many animal species will be unable to adapt and will become extinct.
ANALYZE EACH ANSWER:
-Squirrel and chipmunk species are unable either to consume or to store all the nuts and berries produced during a longer growing season.
Wrong. A shows the “preferred” condition for Squirrel and chipmunk because they will have more food.
-Fungus species typically produce spores only once a year and are unable to produce enough spores to release spores again before the end of a longer growing season.
Wrong. SHELL GAME. The logic is correct, but Fungus is not animal.
-Butterfly species that respond quickly to changes in temperature hatch caterpillars and undergo metamorphosis into butterflies earlier, flying away before bird species that feed exclusively on them have hatched their young.
CorrectThe early growth of butterfly indirectly leads to the extinction of bird.
-Salmon species that rely on changes in temperature to signal the start of annual migrations leave their freshwater birthplaces earlier, before they have fed sufficiently on freshwater insects to reduce their number.
Wrong. D indicates that Salmons will not reduce their number.
-Reptile species that hibernate during winter months must emerge from hibernation sooner and spend a longer time searching for food before mating in mid-summer.
Wrong. Nothing to indicate that reptile will be extinct. E just tells the fact that Reptiles have to change their searching food habit.
Hope it helps.

I got to C pretty easily but wanted to address this. From a scientific perspective, this is right but I think the statement is a poor choice even without that logic. Let's assume Fungus is an animal...all this seems to imply is that they "reproduce" once a year and during the long growing season, there is not enough time for the new offspring to mature in time to reproduce again. (But that doesn't mean the offspring won't produce spores later in time or the following growing season)
