### HideShow timer Statistics

A decade after a logging operation in India began cutting down trees in a territory that serves as a sanctuary for Bengal tigers, the incidence of tigers attacking humans in nearby villages has increased by 300 percent. Because the logging operation has reduced the number of acres of woodland per tiger on average from 15 acres to approximately 12 acres, scientists have theorized that tigers must need a minimum number of acres of woodland in order to remain content.

Which of the following statements, if true, would most strengthen the scientists’ hypothesis?

(A) In other wildlife areas in India where the number of acres of woodland per tiger remains at least 15 acres, there has been no increase in the number of tiger attacks on humans.

(B) Before the logging operation began, there were many fewer humans living in the area.

(C) The largest number of acres per tiger before the logging operation began was 32 acres per tiger in one area of the sanctuary, whereas the smallest number of acres per tiger after the logging operation was 9 acres.

(D) Other species of wild animals have begun competing with the Bengal tigers for the dwindling food supply.

(E) The Bengal tiger has become completely extinct in other areas of Asia.

We have rules, and these must be followed: whenever you say a possible answer, wrong or right it is not important, you should provide an explanation.

In this manner, we learn how to beat the GMAT

Thank you

Hi guyz,
If you give your line of thought, there may be someone who will learn from it or may be someone improves upon that line of thought and you too get benefitted...
IMO A, B, C etc does not serve the purpose and defeats the very purpose the thread has been started on the Q by carcass.

edit:- it seems carcass too has aired his view on the same..

IMHO A , because it correctly supports the conclusion of the Stimulus presented to us, by comparing the situation in Bengal to other areas of India where number of acres of woodland per tiger remained the same.

Hence I would like to mark (A)

Although I selected A, For me A weakens the conclusion. We are assuming that the tigers were satisfied when the acreage was 15. Maybe tigers were not contented before and the attacks were already high.

Actually, the argument says that under a certain threshold of acres the tigers become more aggressive, due to lack of territory. We need something the helps us to reinforce this conclusion , saying the = or above that limit the attacks do not happen. A says this.

Could you elebora<te much better why A weakens the argument ??

thank you

Lets see the argument together. The fact is that there is an increase in rate of tiger attack.
Conclusion is : because there is a decrease in acreage from 15 to 12, tigers attack people.

option A says:In other wildlife areas in India where the number of acres of woodland per tiger remains at least 15 acres,there has been no increase in the number of tiger attacks on humans.
We may assume that the rates of attack were already high @15 acres so it might not strengthen the argument. If we adhere by this then scientists have made a false assumption.

Making sense? :lol:/ :lol:

two points...
1) the Q asks you to find "would most strengthen the scientists’ hypothesis?".
here this is the only choice that strengthens..
2) The line of reasoning that you have written may be correct and required. if they gave you this choice/statement in main para and asked you to--
a) find a flaw in the reasoning, or
b) weakening the argument..

We have to strengthen the scientists' hypothesis:

(A) In other wildlife areas in India where the number of acres of woodland per tiger remains at least 15 acres, there has been no increase in the number of tiger attacks on humans. (Strengthens it indeed!)

(B) Before the logging operation began, there were many fewer humans living in the area. (Irrelevant)

(C) The largest number of acres per tiger before the logging operation began was 32 acres per tiger in one area of the sanctuary, whereas the smallest number of acres per tiger after the logging operation was 9 acres. (Irrelevant)

(D) Other species of wild animals have begun competing with the Bengal tigers for the dwindling food supply. ( Not related to the given premise)

(E) The Bengal tiger has become completely extinct in other areas of Asia. (Doesn't make sense)

Therefore, A

What you are assuming, and chetan2u already pointed out, is something that is not indicated in the stimulus or is outside our argument.

One of the most common mistakes that you can do tackling the GMAT is bringing in info from outside world. They could be correct or not, that's not the point at issue, but is wrong

So, indeed, your reasoning is flawed

Other species of wild animals have begun competing with the Bengal tigers for the dwindling food supply due to smaller woodland availability - which has forced tiger to attack outside of 12 acres

Option 'a' states In other wildlife areas in India where the number of acres of woodland per tiger remains at least 15 acres, there has been no increase in the number of tiger attacks on humans. ... it say no increase in attacks... these sanctuaries may already have more attacks taking place... can this statement define contentment of tigers then?
