(A) Bats are steadily losing natural roosting places such as caves and hollow trees and are thus turning to more developed areas for roosting. --- this doenst state anything against the intention
(B) Bats are the chief consumers of nocturnal insects and thus can help make their hunting territory more pleasant for humans. --- supporting the idea
(C) Bats are regarded as frightening creatures not only in the United States but also in Europe, Africa, and South America. --- supporting the idea
(D) Raccoons and owls are shy and active only at night; yet they are not generally feared and persecuted. --- against the idea
(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. ---- irrelevant

so D is the answer

I still haven't developed a real strategy towards answering these questions, but when focusing on the question asked, the only answer that seem to be relevant to the argument presented was answer D.

The conclusion in this case is "bats are feared and persecuted" and the support for "why the reason they are feared" is provided by the keyword "because" and its following statement "they are shy animals that are active only at night."

Since its a weaken question lets try and find out an answer choice that dismantles the support structure on which the conclusion is drawn. Lets evaluate each of the answer choices

(A) Bats are steadily losing natural roosting places such as caves and hollow trees and are thus turning to more developed areas for roosting.
# Loosing natural habitat doesnt make bats less shy or nocturnal and thats the prime reason for people to fear them. So this choice doesnt do enough or for that matter any damage to the support statement
(B) Bats are the chief consumers of nocturnal insects and thus can help make their hunting territory more pleasant for humans.
# This shows an advantage of bats living in the vicnity of humans, so doesnt weaken the support structure
(C) Bats are regarded as frightening creatures not only in the United States but also in Europe, Africa, and South America.
# This only restates the conclusion by giving some more inforation that other countries also have the same phenomena
(D) Raccoons and owls are shy and active only at night; yet they are not generally feared and persecuted.
# This contradicts the supporting statements saying that only because an animal is shy and nocturnal doesnt mean people are afraid of it - This is the correct answer
(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.
#Goes out of the scope of the argumnet, irrelevant

D

Shy & Active at night(Cause) ->> Fear(Effect)

To weaken this relation we will show that cause is there but no effect.

D is correctly expressing this with the example of Raccoons and owls

In this one we have an example in which we have the same causes but we don't have the effect. So it weaken the argument that said that the only causes are being active during night and shy, and the effect is being persecuted.

Definately a cause and effect argument.

Bats are SHY + NIGHT creatures, so Bats are FEARED and PROSECUTED.

Is there no other reason why bats may be FEARED or PROSECUTED?

Answer D-Other animals are SHY + NIGHT creatures, yet they are not feared. Bats must have some other trait that creates fear among people.

The reasoning in the question stem is A(they are shy animals that are active only at night) -> B(bats are feared and persecute). To weaken this causality, one way is to show that even when A happens, B doesn't happen. That is exactly how D does.

90% of cr weaken questions, revolve around alternate reasoning. Other 10% depend on login in the argument or cause and effect imbalance.The thing to
remember is while using there is cause, but no effect or there is no cause but presence of effect logic in weaken questions,it is slightly acceptable
as to bring a new target group if it weakens.
Straight forward answer:

There is cause(with other creatures) --> But there is no effect (people are not feared)

this question shows the true color of an argument. There must be a relationship, particularly causal relationship between a premise and a conclusion.

(D) most seriously weakens the group's contention. They argue that just because bats are shy and active at night, people are scared of them. (D) provides a counter example in the form of Raccoons and Owls.

It has to be D
The reason is that the group contends that bats are feared because they are active in night and are they are shy.
But D provides us an example of animals showing same type of behavior same as bats but they are not feared , hence the reason must be something else .
