E. Alex does not exhibit aggression when offered a gesture that he specifically requested.

is it C?


Cannot underatans why c is out.
Dogs too express concern and communicate.
Alex does not exhibit aggression does not say that he tries to communicate and tell that he is satisfied.

Hi,
You can use your real world knowledge in GMAT CR . Take the given facts as real . In option 'C' it says Dogs sense sadness ( which is a gesture) , this option mentions nothing about language communication.
Whereas , in option 'E' , it confirms the parrot understand what he is asking. It is not just he has memrized a word and doesn't know its meaning . Hope it is clear now :)

Conclusion is animals other than primates can communicate. A,B,C,D shows high cognitive abilities that does not mean they are able to communicate.
E strengthens the conclusion as it removes the doubt, that alex shows aggression for all kinds of gestures

So answer should be E

The conclusion of the argument is that humans and primates are not the only animals capable of communicating with language. The basis for this claim is that a parrot named Alex becomes upset when he is not given the gesture he verbally requests. We are asked to strengthen the claim.
(A) The conclusion is about non-primates or non-humans being able to use language to communicate. Assisting divers in ocean rescues is not relevant.
(B) The conclusion is about non-primates or non-humans being able to use language to communicate. Gorillas are primates, as stated in the first sentence of the argument.
(C) Sensing the mood of one’s owner and exhibiting concern is not a form of language communication.
(D) The conclusion is about non-primates or non-humans being able to use language to communicate. Chimpanzees are primates, as stated in the first sentence of the argument.
(E) CORRECT. If Alex does not exhibit aggression when offered a gesture that he specifically requested, it suggests that Alex can tell the difference between the gestures that he requests and those that he does not. In other words, he is a non-primate / non-human but he is communicating via language. If he also exhibited aggression when offered the gestures he requested, it would be more difficult to claim that he was communicating via language.

Hello Mike, Would you please take a look at this question: it's becoming rather controversial. Thanks

I don't know the source, but my understanding is that the OA is (E).

The argument takes for granted that higher-order primates (chimpanzees, gorillas, and human) have higher cognitive function, including language. The argument asserts that many other animals, including parrots and possibly dogs & dolphins, also have the ability to use language to communicate. That phrase is key to understanding this question.

First of all, choices (B) & (D) add further examples of higher-order primates doing sophisticated thinking. No matter how sophisticated the thinking of higher-order primates, this tells us zilch about whether animals outside of the higher-order primates have any sophisticated abilities. These are irrelevant.

Choice (A) is deceptive. As you may know from outside sources, dolphins are pretty clever. If this had been an example of dolphins doing something very sophisticated, then that could be a strengthener. As it happens, many many animals (even insects!!) can be trained to do things. It's not at all clear whether being trained to assist in ocean rescues would involve very sophisticated skills or tremendously easy things to do (e.g. tow someone or something to the surface). Because the nature of this activity is not clear, we cannot say this is a clear strengthener, so it cannot be correct.

Choice (C) is about emotions. The abilities to feel emotions and to sense emotions in others are not cognitive abilities at all. Yes, the ability to talk about emotions, or write poetry evoking emotions, or something such as that --- those involve cognitive skills, but simply feeling emotions or sensing emotions is not cognitive at all. That's why (C) is irrelevant.

This only leave (E). Think if this were false. If the parrot Alex were always aggressive, then the aggression would have nothing to do with what he said in words, and this would destroy the only solid piece of evidence in the argument. The only way Alex's aggression to an unrequested gesture would make sense as a piece of evidence would be if he show no aggression to a requested gesture. Therefore, (E) is a clear strengthener --- it reinforces one assumption of the argument.

Overall, this is a good question, although it may demand an awfully sophisticated understanding of either psychology or cognitive science --- a little more background than the GMAT would typically expect.

Does all this make sense?
Mike :-)


thanks Mike for the terse explanation. :)
It helped me catch the little thing about feeling the emotions mentioned in option D.

Official solution



The conclusion of the argument is that humans and primates are not the only animals capable of communicating with language. The basis for this claim is that a parrot named Alex becomes upset when he is not given the gesture he verbally requests. We are asked to strengthen the claim.

(A) The conclusion is about non-primates or non-humans being able to use language to communicate. Assisting divers in ocean rescues is not relevant.

(B) The conclusion is about non-primates or non-humans being able to use language to communicate. Gorillas are primates, as stated in the first sentence of the argument.

(C) Sensing the mood of one’s owner and exhibiting concern is not a form of language communication.

(D) The conclusion is about non-primates or non-humans being able to use language to communicate. Chimpanzees are primates, as stated in the first sentence of the argument.

(E) CORRECT. If Alex does not exhibit aggression when offered a gesture that he specifically requested, it suggests that Alex can tell the difference between the gestures that he requests and those that he does not. In other words, he is a non-primate / non-human but he is communicating via language. If he also exhibited aggression when offered the gestures he requested, it would be more difficult to claim that he was communicating via language.

The conclusion of the argument is that humans and primates are not the only animals capable of communicating with language. The basis for this claim is that a parrot named Alex becomes upset when he is not given the gesture he verbally requests. We are asked to strengthen the claim.

Conclusion: Humans and primates are not the only animals capable of using language to communicate.
Support: Some animals, such as dolphins, dogs, and African grey parrots, seem to exhibit cognitive functions typically associated with higher-order primates such as chimpanzees, gorillas, and humans.
Example 1: Some parrots have vocabularies of hundreds of words that they can string together in a comprehensible syntax, Alex.

Now Since the conclusion is not about the primates and humans, B and D can be ruled out . Now since we are talking about communication via language , C can be ruled out. For A also, there is no language involved for communication ( not sign language ?) So, left with answer choice E which is correct. Also, since Alex can communicate via language and responds according to gesture offered.

(A) The conclusion is about non-primates or non-humans being able to use language to communicate. Assisting divers in ocean rescues is not relevant.
(B) The conclusion is about non-primates or non-humans being able to use language to communicate. Gorillas are primates, as stated in the first sentence of the argument.
(C) Sensing the mood of one’s owner and exhibiting concern is not a form of language communication.
(D) The conclusion is about non-primates or non-humans being able to use language to communicate. Chimpanzees are primates, as stated in the first sentence of the argument.
(E) CORRECT. If Alex does not exhibit aggression when offered a gesture that he specifically requested, it suggests that Alex can tell the difference between the gestures that he requests and those that he does not. In other words, he is a non-primate / non-human but he is communicating via language. If he also exhibited aggression when offered the gestures he requested, it would be more difficult to claim that he was communicating via language.

Correct answer, because the understanding means that the animal to be able to act upon the understanding and differentiate between the language and signs
