A: A. linifolius has a short
life-span. out of scope, not talking about the life-span but reproduction
B: A. linifolius is also pollinated, though to a much-lesser degree, by some local species of bees. doesn't strengthen the idea that the pesticide should be banned
C:
The pesticides that control insect herbivores other than grasshoppers are even more toxic to Bombylius flies. irrelevant not talking about the pesticides that control insect herbivores
D: Bombylius flies do not reproduce very fast and their populations do not recover for many years after one spraying of a pesticide that controls grasshoppers.
CORRECT if the Bombylius flies do not reproduce very fast then it will be difficult for the A.Linifolius plant to reproduce as well, thus decreasing the population sharply.
E:
The populations of some other plant species in the Colorado region have decreased to an even greater extent than the population of A. linifolius since the spraying of pesticides that control grasshoppers first started in the region.
out of scope, the population of the other plant doesn't affect the population of this A.linifolius plant
