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?



Squirrel and chipmunk species are unable either to consume or to store all the nuts and berries produced during a longer growing season.

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.

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.

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.

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.

B for me!

I will go with D. If Salomon species have not fed sufficiently, chances are of earlier extinction.

I choose C.

Birds do not feed other species, so their young may die because of lack of food.

A - Squirrel and chipmunk species have an oversupply of food. This weakens the extinction argument.
B - No change in the number of spores. Offers no support for the argument.
C - Caterpillars, the exclusive food source for young birds, are no longer available. This poses a threat for this particular bird species. Correct.
D - In this case, the number of salmon has increased, thus weakening the extinction argument.
E - Searching for food longer does not necessarily mean that the reptile population will shrink. Besides, there might be more food now.
