A few decades ago it was popular to link dramatic increases in urban antisocial behavior with high population density, and to support this with studies of laboratory rats, which exhibit randomly violent behavior under conditions of extreme overcrowding. It has since become obvious that the analogy between rats and humans is simplistic at best, and leaves out considerations like human adaptability and cultural factors that are of key importance in determining human behavior.

Which of the following, if true, best supports the conclusion the author presents in the passage above?

A) Testing new products on laboratory rats has sometimes led to unnecessary alarm about their adverse effects on human health.
B) Rats thrive in the crowded conditions of human urban society.
C) Rats also exhibit unnatural behavior in conditions of extreme isolation.
D) Although rat behavior does change in crowded conditions, what results is not random violence but a new, radically different social order.
E) In some extremely crowded cities there is relatively little antisocial behavior, whereas some sparsely – populated rural communities have very high rates of such behavior.

The answer should be (E).

The question says that the analogy between humans and rats is simplistic, because of factors like human adaptability and cultural behavior that determine the behavior of humans (and not rats).

(A): Testing new products on rats has no relation to the behavior they exhibit in different conditions. Incorrect.
(B): We cannot determine the response of rats or humans by the behavior of rats in crowded human conditions. Incorrect.
(C): Even if rats exhibit unnatural behavior in crowded conditions, we must have some way of comparing this with what humans do in such conditions to draw a meaningful inference. This information is not provided so we cannot make the comparison. Incorrect.
(D): If rats exhibit not random violence but a new, different social order then this would oppose the author's argument - rats would seem to be exhibiting adaptability, similar to what humans do. It would then become difficult to distinguish between the two. Incorrect.
(E): CORRECT. If there is little violent behavior in some crowded human societies, and higher violent behavior in some sparsely populated communities, it means that human behavior is changing according to adaptation. This is not the behavior exhibited by mice - which seem to consistently exhibit violent behavior in conditions of extreme overcrowding. Therefore this choice elucidates the difference between human and rat behavior.

We need to weaken the the stand that humans behave like rats. This is weakened in E, as E states that In some extremely crowded cities there is relatively little antisocial behavior, whereas some sparsely – populated rural communities have very high rates of such behavior. This is opposite to the way rats behave hence we have strengthen the conclusion.

NO other options does this, they all either give additional info or dont strengthen.

I hope i am able to explain as clearly as possible. if not please let me know

Q : A few decades ago it was popular to link dramatic increases in urban antisocial behavior with high population density, and to support this with studies of laboratory rats, which exhibit randomly violent behavior under conditions of extreme overcrowding. It has since become obvious that the analogy between rats and humans is simplistic at best, and leaves out considerations like human adaptability and cultural factors that are of key importance in determining human behavior.

The conclusion of this argument is - Analogy between rats and humans is simplistic but it leaves out considerations like human adaptability and cultural factors that are of key importance. So the answer choice must show that this analogy indeed has some weaknesses because it does not consider human adaptability and cultural factors that also affects human behaviour.
The argument mentions that extreme overcrowding leads to violent behaviour in rats and then make a generic conclusion by analogy of humans with rats but Answer choice 'E' explains that this analogy may not always be true because it has not considered human adaptability and cultural factors (E - Cities are crowded but little antisocial behaviour and vice versa).


Which of the following, if true, best supports the conclusion the author presents in the passage above?

A. Testing new products on laboratory rats has sometimes led to unnecessary alarm about their adverse effects on human health. - While this may be true, it does not explicitly mention about the human behaviour affected by adaptability and culture.
B. Rats thrive in the crowded conditions of human urban society. - Out of Scope
C. Rats also exhibit unnatural behavior in conditions of extreme isolation. Out of Scope
D. Although rat behavior does change in crowded conditions, what results is not random violence but a new, radically different social order. - Out of scope.
E. In some extremely crowded cities there is relatively little antisocial behavior, whereas some sparsely – populated rural communities have very high rates of such behavior. - Correct, Explained above.


Press +1 Kudos if you like the explanation

Fact: A few decades ago, dramatic increases in urban antisocial behavior was linked with high population density
Fact: Laboratory rats exhibit randomly violent behavior under conditions of extreme overcrowding
Fact: However, the analogy between rats and humans is simplistic at best ["simplistic at best" means too simple or incomplete]

Conclusion: KEY factors in determining human behavior are Human adaptability and cultural factors, NOT population density.

To strengthen the conclusion, we need to show in crowded cities, there is relatively little antisocial behavior. That will support the conclusion that population density is NOT KEY importance in determining human behavior.

E states exactly the same, hence is correct.

Hope it helps.

Which of the following, if true, best supports the conclusion the author presents in the passage above? - This is a Justify the Conclusion question, but not strengthening question. To answer this type of question, there is a formula: Premise + Correct Answer Choice = Conclusion. If you choose answer (A), it would read, "A few decades ago it was popular to link dramatic increases in urban antisocial behavior with high population density, and to support this with studies of laboratory rats, which exhibit randomly violent behavior under conditions of extreme overcrowding. Testing new products on laboratory rats has sometimes led to unnecessary alarm about their adverse effects on human health. It has since become obvious that the analogy between rats and humans is simplistic at best, and leaves out considerations like human adaptability and cultural factors that are of key importance in determining human behavior." Does this logically make sense? No!

However, if you choose answer (E), it would read, "A few decades ago it was popular to link dramatic increases in urban antisocial behavior with high population density, and to support this with studies of laboratory rats, which exhibit randomly violent behavior under conditions of extreme overcrowding.

It has since become obvious that the analogy between rats and humans is simplistic at best, and leaves out considerations like human adaptability and cultural factors that are of key importance in determining human behavior." Does this logically make sense? Yes! So, the correct answer is (E). Hope this helps!

It has since become obvious that the analogy between rats and humans is simplistic at best, and leaves out considerations like human adaptability and cultural factors that are of key importance in determining human behavior.

Which of the following, if true, best supports the conclusion the author presents in the passage above?

Given: Earlier : High population density --> Urban Anti Social behavior. Corroborated by studies of laboratory rats, which exhibit randomly violent behavior under conditions of extreme overcrowding.

Conclusion: Analogy betn Rates and Human is simplistic and does not consider human adaptability and cultural factors.


A. Testing new products on laboratory rats has sometimes led to unnecessary alarm about their adverse effects on human health. Irrelevant

B. Rats thrive in the crowded conditions of human urban society. Irrelevant

C. Rats also exhibit unnatural behavior in conditions of extreme isolation. Irrelevant

D. Although rat behavior does change in crowded conditions, what results is not random violence but a new, radically different social order. Irrelevant

E. In some extremely crowded cities there is relatively little antisocial behavior, whereas some sparsely – populated rural communities have very high rates of such behavior. Two cases: in one Cause but no effect and in 2nd effect but no Cause. That means there are other factors other than crowding which are also in play to cause anti social behavior.

E. In some extremely crowded cities there is relatively little antisocial behavior, whereas some sparsely – populated rural communities have very high rates of such behavior.

In question stimulus, "laboratory rats, which exhibit randomly violent behavior under conditions of extreme overcrowding", it says randomly which is the deciding factor in the answer choice.

in option D :
D. Although rat behavior does change in crowded conditions, what results is not random violence but a new, radically different social order. - It is not random. So D is eliminated.

in option E :

E. In some extremely crowded cities there is relatively little antisocial behavior, whereas some sparsely – populated rural communities have very high rates of such behavior. - Here randomness is seen. So E is correct option.
