A conservation group in the United States is trying to change the long-standing image of bats as frightening creatures. The group contends that bats are feared and persecuted solely because they are shy animals that are active only at night.

Which of the following, if true, would cast the most serious doubt on the accuracy of the group’s contention?

(A) Bats are steadily losing natural roosting places such as caves and hollow trees and are thus turning to more developed areas for roosting.
(B) Bats are the chief consumers of nocturnal insects and thus can help make their hunting territory more pleasant for humans.
(C) Bats are regarded as frightening creatures not only in the United States but also in Europe, Africa, and South America.
(D) Raccoons and owls are shy and active only at night; yet they are not generally feared and persecuted.
(E) People know more about the behavior of other greatly feared animal species, such as lions, alligators, and snakes, than they do about the behavior of bats.

A- because it says bats are now moving to more developed area for settling where as the group say bats are shy animals. Shy animals dont move into a area where there are lots of people.

Other choices are all irrelevant

D?
Argument conclusion: bats are feared solely because they are shy animals that are active only at night.
D weakens it.

the people who picked D.. is D not out side of the argument? because, in the argument description, author talking about bats only right? for Raccoons and Owls that may be the case but for bats, that may not be the case?

I thought A makes more sense because, they are coming closer to developed areas (means they will involve with crowd) says that they are not shy...

where am I missing the point?

For weaken or strengthen question, you need to focus on the conclusion of the argument. The correct answer choice should impact the conclusion. The conclusion of this argument said the bat is feared solely because it is shy and active only at night. Answer D shows there might be other reasons the bat is feared. The question's focus is not whether the bat is shy or not shy. The focus is whether the bat is feared only because it is shy. (Pay attention to the word solely.)

D for me by process of elimination.

A)
certainly offers an alternative theory to why bats may be persecuted - because they come into contact with humans since they are losing their roosting places and moving into human territory. However the main argument is that humans persecute bats because they are shy so this choice does not do anything to cast doubt on that argument

B) - same as A. Good alternative theory that does nothing to address the main reason the group thinks bats are persecuted.

C) Is irrelevant. So they're frightening in Europe, Africa and S.America - so what? It does not address the theory posed in the question (people persecute bats because they are shy)

D) Now this to me seems to offer a counter argument to the theory. Why don't people persecute racoons and owls yet they exhibit the same characteristics as bats?

E) Actually strengthens the argument posed. That people persecute bats because they do not understand them.

My pick: D

The reasoning is : bats are shy => we fear bats.
D says that others such as racoons and owls are shy but we do not fear them. D wins.

This is third family question (weaken question), so answer should be accepted as given even if it is not in the stimulus.. In this question D can be an alternative explantion or more appropriatly a valid counter argument, which will weaken the author conclusion.

I agree. I think bats are shy. They only come out at night and when the are sleeping they cover their face. What a unique characteristic of a shy mammals.

after reading the cause and affect reasoning chapter in Powerscore Bible i came to the conclusion that if there is an alternate cause for the effect then it should weaken the argument.
here
Bats are shy animal(cause)->bats are persecuted(effect)

choice A gives an alternate cause they come to developed areas.I conder D as an Answer but when i approach the problem after reading Powerscore Bible i choose A.What's the mistake in this approach
