By competing with rodents for seeds, black ants help control rodent populations that pose a public health risk. However, a very aggressive species of blank ant, the Loma ant, which has recently invaded a certain region, has a venomous sting that is often fatal to humans. Therefore, the planned introduction into that region of ant flies, which prey on Loma ants, would benefit public health.

Which of the following, if true, most strengthens the argument?

A. Ant flies do not attack black ants other than Loma ants.
B. Loma ants are less effective than many bird species in competing with rodents for seeds.
C. Certain other species of black ants are more effective than Loma ants in competing with rodents for seeds.
D. The sting of Loma ants can also be fatal to rodents.
E. The use of pesticides to control Loma ants could have harmful effects on the environment.

A is best. Since it doesn't attack other black ants other than loma ants, then there are still populations of blacks ants that keeps the rodent population in control.

E. The use of pesticides to control Loma ants could have harmful effects on the environment.

B C D are wrong.
While A and E both strengthen, the conclusion is inferred from the premise that the planned introduction of ant flies benefits public health. Thus, a premise where ant flies is an advantage should be the correct answer. Eliminate E and answer is A.

1) Rat causes disease to human ===> Rats are bad for humans
2) Ant control rat population ===> Ant kills rat and helps humans to stay healthy. Ants are good for humans
3) But Loma Ant kills human ====> one type of ant Loma Ant is bad for humans.
4) Fly will kill Loma ant===> Loma ant will die = Human safe and healthy again

What if the fly kill all types of ant, then according to equation 2 rat population will increase==> when rat population increase then according to equation 1 human get disease.

So how can we strenghten the fact that flies would be good for humans?

Option A says that flies will kill only loma ant but not other ants.

This options doubly strengthen the argument:-
HUMANS will not die of loma ant poison
Other ant population will not decrease and these ant will keep killing rats, (so human will not get disease)

PERFECT CHOICE IS A

A is the answer. Very easy thinking.

Black ants also provide health benefit and should be protected.
