During the recent spate of brushfires in the Southwest, homeowners who lived near affected areas were advised to douse their roofs with water to prevent their houses from catching fire, before evacuating the area. After the fires were brought under control and the homeowners were allowed to return to the area, many who doused their roofs discovered significant fire damage to their houses. Clearly, then, dousing their roofs was a wasted effort.

Which of the following, if true, would most weaken the conclusion above?

A)The houses of owners who did not douse the roofs with water suffered appreciably more fire damage than did those of owners who did douse the roofs with water.

B)Not all homeowners who doused their roofs did so to the same extent.

C)The fire insurance rates for those who doused their roofs did not increase after the fire.

D)The houses that suffered the least damage were those in which the owners remained and continuously doused the roofs.

E)Most of the homeowners who doused their roofs had been through a brushfire evacuation before.

A

The argument is that "even though the houses were doused with water, the damage was extensive. Hence it was not useful to douse the house with water".

To weaken the argument, we have to find something that would suggest that dousing helped.

Answer choice A, says that "people who doused their house with water had significantly less damage than others who didn't"

So the answer choice is A

Clearly A

C: Dousing was a wasted effort.

If A is true then dousing was beneficial. Therefore it was not a wasted effort.

A

Conclusion: Dousing roofs was a wasted effort.

Premise: People who doused their roofs discovered significant fire damage to their houses.

How can be provide an evidence that undermines the premise and hence conclusion.

A is doing that. Eventhough houses that were doused had fire damage but houses that were not doused were even more damaged. It means dousing was not a waste of effort.

D -
"The houses that suffered the least damage were those in which the owners remained and continuously doused the roofs"

would this not be a better answer?

Seems out of scope.

See the bold part:
During the recent spate of brushfires in the Southwest, homeowners who lived near affected areas were advised to douse their roofs with water to prevent their houses from catching fire, before evacuating the area. After the fires were brought under control and the homeowners were allowed to return to the area, many who doused their roofs discovered significant fire damage to their houses. Clearly, then, dousing their roofs was a wasted effort.

So we are not that much concerned about people who remained in their houses.

Yes, (A). Those who doused their rooves were spared the heaviest damage. D doesn`t goes out of scope because those homeowners never even evacuated in the forst place.

The correct answer is A. The conclusion of the argument is that dousing the roofs
with water was a wasted effort. The basis for this claim is that the houses of
those who doused their roofs still suffered fire damage. We are asked to weaken
this conclusion.
Choice A states that the houses of owners who did not douse the roofs with
water suffered appreciably more fire damage than did those of owners who did
douse the roofs with water. This weakens the conclusion because it suggests
that dousing the roofs was not a wasted effort. Correct.

Please explain why can it not be C?

If the insurance rates did not go up for those who put in efforts to douse the fire, then it would be a great relief to those guys.

A, on the other hand only gives a relative comparison. When in fact, dousing the fire looks to be a wasted effort because their houses did get damaged by fire, even though it was less as compared to those who did not douse the fire.

So, comparatively speaking, between A & C, A is more directly showing the good stuff about dousing the fire.

A)The houses of owners who did not douse the roofs with water suffered appreciably more fire damage than did those of owners who did douse the roofs with water.
This choice clearly weaknes the argument since it provides facts that the damage to the doused houses was lesser than the damage on the house which were not doused.

B)Not all homeowners who doused their roofs did so to the same extent.
the extent of the dousing is not being discussed in the arguement.

C)The fire insurance rates for those who doused their roofs did not increase after the fire.
Fire insurance is out of scope

D)The houses that suffered the least damage were those in which the owners remained and continuously doused the roofs.
the argument discuss about the houses where the owners were asked to leave and returned after the fire was controlled and found and assesed the damages to their houses respectively.

E)Most of the homeowners who doused their roofs had been through a brushfire evacuation before.
The point is out of scope as it des not provide information about the damages suffered from the fire.
