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 author intends to convey that human behavior is also guided by other factors such as culture and adaptability and not just population. hence , the conclusion drawn from the mice experiment is simple one. To strengthen his case we can give an example that shows that human behavior is affected by conditions much more than population. That's exactly what E does. E Wins.

i think C supports the similarity between rats and human behavior.


I think it should be E.

The problem with C is that it states the effect can be seen even with an alternative cause. The argument says that rat's violent nature can be seen when they are exposed to overcrowded situations. However, option C is trying to explain the same characteristics can be developed even they are alone. This is simply an alternative cause, which is wrong in the context of a supporting CR question.

My ans is A, the conclusion says that the analogy b/w rats and humans are simplistic best and leaves out the other factors which determine human behaviour and we have to choose an option which strengthens the conclusion, how can it be E


A is incorrect we are not comparing lab products as those might actually harm humans; the author is talking about adapting to a situation.

E is correct as if you will negate it, some becomes none . This would mean that the argument would not hold, as it would prove humans are not able to adapt as rats do not. Therefore, the statement actually strengthens the conclusion that humans are able to adapt.

I will go with E.... E looks more appropriate

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