Re: In the past year, there has been a dramatic increase in the number of [#permalink]
2 things happened

A-----> In the past year, there has been a dramatic increase in the number of people killed by alligators in Florida.

B-----> During this same time, there has been an increase in the development of new houses, golf courses, and shopping areas in former wilderness areas within the state.

Therefore, the increase in fatal alligator attacks must have been caused by the increase in the number of humans living in the alligator’s habitat.

The author takes 2 events and concludes that fatal alligator attacks must have been caused by the increase in the number of humans living in the alligator’s habitat.

This is a classic example of taking 2 events that happened simultaneously and trying to establish a cause and effect relation

what if it was a co incidence. There is no evidence given by the author that these events are causally related.

To weaken this we have to show that these events are not causally related or that number of attacks increased not cause of increased human population living in alligator's habitat.


Option A . Two years ago, a government initiative to reduce the alligator population size by destroying alligator eggs ended.
This gives us a clear indication that the thing which reduced alligator population stopped. Therefore now there were more alligators in the wild. This shows us that alligator attacks increased not cause of increase in human population, but cause there were now more alligators than before.

Which of the following, if true, most seriously calls into question the explanation above?


A. Two years ago, a government initiative to reduce the alligator population size by destroying alligator eggs ended.

B. An increase in fatal alligator attacks tends to make people more cautious around lakes, ponds, swamps and canals.

C. The number of people killed by snake bites, spider bites and scorpion stings in Florida has held steady for many years.

D. Many of the new state residents have moved to newly constructed areas near water that is suitable for habitation by alligators.

E. The undeveloped areas of Florida have decreased in area by 5% in the past year.



We are required to weaken the explanation (aka conclusion) offered for WHY there has been an increase in fatal alligator attacks.

A. Puts forth an alternate reason for why attacks have increased, thus clearly calling the explanation offered by the author into question

B. This can be seen as a consequence of the attacks, while we're interested in the cause

C. Irrelevant as the attacks by other animals do not impact the explanation offered about alligator attacks

D. Strengthener as it directly supports the author's view that the attacks have increased because of "the increase in the number of humans living in the alligator’s habitat"

E. Additional info supporting the argument

Can anybody help me understand...why d is wrong...
This question is all about find out a option which is 'if true' will call into question the given explanation...means cast doubt on given explanation.....


Ans A says two years back initiative to reduce the alligator population size by destroying alligator eggs ended...2 years back it ended...but past year there has been a dramatic increase in the number of people killed by alligators in Florida... because no killing of eggs...so many deaths are due to alligator attack...this way...ans A is supporting the explanation......how it is casting doubts on given explanation

In this argument, the author explains what he believes is the cause of the increase in alligator attacks. His explanation forms the conclusion of the argument: "Therefore, the increase in fatal alligator attacks must have been caused by the increase in the number of humans living in the alligator’s habitat."

This conclusion is what we need to call into question.

Option A puts forth an alternate reason for why attacks have increased. Because the government stopped destroying alligator eggs two years ago, the eggs that were not destroyed have hatched, thus increasing the alligator population. Therefore, alligator attacks have gone up because there are more alligators, not because of the increase in humans in the alligator's habitat. Thus, it clearly calls the explanation offered by the author into question

Option D is a strengthener as it directly supports the author's conclusion

Hope this helped a bit!

I think if we think this way then it brings more clarity why a is correct....two years back there was initiative to reduce alligator population by destroying their eggs....now last year this initiative was not there because there was no alligator left...so no deaths would have been caused by alligator.... whereas it has been stated that more deaths are due to alligator attacks..so this way A cast doubt on given explanation......
