The growing popularity of biofuel has caused a greater percentage of farmland to be devoted to corn rather than soybeans, the other major crop. A pesticide manufacturer argues that this transition has led to an increase in soybean aphids, a pest that damages soy crops and reduces soybean yield, but does not live on corn. The manufacturer attributes the increase to the reduced acreage of soy crop, which translates into fewer habitats for the insects that prey on the soy aphid.
The pesticide manufacturer's argument makes which of the following assumptions?
A. The insects that prey on the soy aphid do not prey on any other species.
B. Soybean aphids cannot be killed by traditional pesticides.
C. The larger the amount of farmland devoted to soybeans, the more important it is that soy aphids are eliminated.
D. The proximity of a soybean crop to a corn crop has little effect on the presence of soy aphids.
E. The decrease in available habitats more seriously affects the insects that prey on the soy aphid than the soy aphid itself.

manufacturer is basically saying, reduced acerage for soyabean caused reduced habitat for insect that eats aphids resulting into increase in aphids.
so here the assumption must be that the reduced area for soyabean didn't affect aphids as much as they affect the insects that feeds on them.
option E gets the job done.

The pesticide manufacturer's argument claims that the increase in soybean aphids is due to the reduction in soybean acreage, which results in fewer habitats for the insects that prey on soybean aphids. For this argument to hold, the assumption must be that the reduced soybean acreage harms the predators of soybean aphids more than it harms the aphids themselves.
Let's look at each option:
A. The insects that prey on the soy aphid do not prey on any other species.
This is not an assumption necessary for the argument. The argument focuses on the predators of soy aphids needing habitats, not whether they prey on other species.
B. Soybean aphids cannot be killed by traditional pesticides.
This is irrelevant to the argument. The manufacturer’s claim is about habitat reduction affecting predator populations, not the effectiveness of pesticides.
C. The larger the amount of farmland devoted to soybeans, the more important it is that soy aphids are eliminated.
This is also irrelevant. The argument is about the relationship between the amount of farmland for soybeans and the predators of aphids, not the need to eliminate aphids.
D. The proximity of a soybean crop to a corn crop has little effect on the presence of soy aphids.
This would be relevant if the argument was trying to link corn to aphid presence. However, the manufacturer is attributing the rise in aphids to the reduction in soybean crops, not proximity to corn. Thus, it is not an assumption made by the argument.
E. The decrease in available habitats more seriously affects the insects that prey on the soy aphid than the soy aphid itself.
This is the key assumption. The pesticide manufacturer's argument hinges on the idea that reducing the number of soy fields harms the predators of soy aphids more than it harms the aphids, leading to an increase in aphid populations.
The correct answer is E.
