The ground water level in County A has decreased drastically over the last few years due to increased ground water consumption. It has been observed that households that do not harvest rainwater inevitably end up consuming greater amounts of ground water than households that use alternative water sources. Therefore, in order to curb the decrease in ground water level, the government has proposed a law making it mandatory for all households to install rainwater-harvesting systems.

Which of the following, if true, would best establish the validity of the government's proposal?


(A)Unharvested rainfall in County A does not significantly boost its ground water level due to the rocky terrain.
(B)Multiple rainwater harvesting systems can store water not only for immediate consumption.
(C)Rainwater harvesting systems conserve less water than certain water recycling systems do.
(D)The new law will place a substantial financial burden on most households.
(E)Households that participate in the program would be less dependent on ground water than would households that do not participate.

It is weird as question because generally the evaluate the argument in OG use always the word at the beginning of the answer "weather"..

C D and E are out od scope

B is not related to the argument ...or irrelevant.

A is the best but is weird as question...the source ?''

You 're right . There was something weird with 'A' that's the reason I wanted to validate it here . I picked it from some online resource for practice . I should refrain from picking random questions like that .

Anyhow , thanks for giving it a shot & highlighting a valuable point .

Here's the explanation-


Analysis: Greater consumption of ground water = lower water level. Rainwater harvesting reduces ground water consumption. CONCLUSION: Rainwater harvesting will curb the decrease in ground water level.

Prediction: To strengthen the argument, the right answer must show that unforeseen circumstances will not prevent the rainwater-harvesting systems from curbing the decrease in water level.

A. Correct. This ensures that harvesting rainwater does not further decrease the ground water level.

B. This information is out of scope.

C. The comparison of rainwater-harvesting systems with recycling systems is irrelevant to the argument.

D. The financial side of the plan is irrelevant to the argument.

E. This was already stated in the argument.
