Atrens: An early entomologist observed ants carrying particles to neighboring ant colonies and inferred that the ants were bringing food to their neighbors. Further research, however, revealed that the ants were emptying their own colony’s dumping site. Thus, the early entomologist was wrong.

Atrens’s conclusion follows logically if which one of the following is assumed?

(A) Ant societies do not interact in all the same ways that human societies interact.

(B) There is only weak evidence for the view that ants have the capacity to make use of objects as gifts.

(C) Ant dumping sites do not contain particles that could be used as food.

(D) The ants to whom the particles were brought never carried the particles into their own colonies.

(E) The entomologist cited retracted his conclusion when it was determined that the particles the ants carried came from their dumping site.

Atrens: An early entomologist observed ants carrying particles to neighboring ant colonies and inferred that the ants were bringing food to their neighbors. Further research, however, revealed that the ants were emptying their own colony’s dumping site. Thus, the early entomologist was wrong.

The early entomologist had assumed that the ants are bringing food to the neighbors

Prethinking : If the early entomologist is wrong then that is possible if the "particles" that ant are dumping at the neighbor colonies are NOT food/

Atrens’s conclusion follows logically if which one of the following is assumed?

(A) Ant societies do not interact in all the same ways that human societies interact. [This is irrelevant - we are not interested in knowing how ants interaction is different from humans]

(B) There is only weak evidence for the view that ants have the capacity to make use of objects as gifts. Out of scope - even if they make use of objects as gifts, how does that tell us, if the things dumped are not food?

(C) Ant dumping sites do not contain particles that could be used as food. [This should be the CORRECT answer - Because if this is true, then the conclusion of Atrens will be logical and the early entomologist's assumption that the ants bring food would be incorrect.]

(D) The ants to whom the particles were brought never carried the particles into their own colonies.Irrelevant - What the ants did with the particles is not the concern here.

(E) The entomologist cited retracted his conclusion when it was determined that the particles the ants carried came from their dumping site. This retraction does not mean that the particles carried were not food, which was the conclusion of the entomologist. The retraction could be because of some other reasons.

Atrens: An early entomologist observed ants carrying particles to neighboring ant colonies and inferred that the ants were bringing food to their neighbors. Further research, however, revealed that the ants were emptying their own colony’s dumping site. Thus, the early entomologist was wrong.

Atrens’s conclusion follows logically if which one of the following is assumed?

Why would entomologist say that the particles that the ants were carrying were food particles? Because they thought that the dumping sites contained food items and that's how they inferred that the ants were bringing food to their neighbors.

BUT they were proved wrong that means we have to eliminate the possibility that the dumping sites contained food. That's exactly what C does. It eliminates the possibility that the dumping sites contained food particles and hence is our answer.

(A) Ant societies do not interact in all the same ways that human societies interact.
Comparing interactions of ants with that of human societies' interaction is absolutely out of scope.

(B) There is only weak evidence for the view that ants have the capacity to make use of objects as gifts.
What kind of gift are we talking about about, were they food particles or something else? who knows! Eliminate.

(D) The ants to whom the particles were brought never carried the particles into their own colonies.
Whether they carried the particles or didn't doesn't really matter and hence this option is out of scope too.

(E) The entomologist cited retracted his conclusion when it was determined that the particles the ants carried came from their dumping site.
Entomologists changed the mind. Who cares! Does it impact the argument? Absolutely not. Because our argument is based on the fact they said for the first time.

this source is from LSAT, i now realize how different LSAT is from GMAT.
C is the answer b/c it connects directly with the argument.
In LSAT, patterns in options are harder to recognize.
