Rye sown in the fall and plowed into the soil in early spring leaves a residue that Is highly effective at controlling broad-leaved weeds, but unfortunately for only about forty-five days. No major agricultural crop matures from seed in as little as forty-five days. Synthetic herbicides, on the other hand, although not any longer-lasting, can be reapplied as the crop grows. Clearly, therefore, for major agricultural crops, plowing rye into the soil can play no part in effective weed control.
The argument is most vulnerable to the objection that it fails to

(A) consider that there might be minor, quick-growing crops that do mature in forty-five days or less
(B) identify any alternative method of weed control that could be used instead of the method it rejects
(C) distinguish among the various kinds of synthetic herbicides
(D) allow for the possibility of combining the two weed-control methods it mentions
(E) allow for the possibility that plants other than rye, handled the same way, might have the same effect.

Please explain in a detailed reasoning.Nice explanation will be appreciated with kudos :)) . OA after explanations.


Answer is D. Explanation: Author totally rejects rye as a means to control weeds ignoring the fact that it can be very effective for first 45 days of a crop cycle which may then followed by synthetic herbisides. This proves others conclusion is incorrect

I believe the answer is D.

A The argument does consider the minor crops

B Does talk about an alternative with synthetic herbicide

C Does distinguish between rye and synthetic

D Looks the best to me. The argument is very harsh on rye, " play no part". There could be a part rye could play if rye and synthetic herbicide is used together

E Irrelevant to the dicussion

My take:
In order to weaken the conclusion "for major agricultural crops, plowing rye into the soil can play no part in effective weed control", we can show that the rye actually can contribute to the crop by combining the two weed-control methods: rye and synthetic herbicides. D shows this.

Can somebody throw some light on this part of the sentence "Synthetic herbicides, on the other hand, although not any longer-lasting, can be reapplied as the crop grows. "???

I think it means herbicides can not last longer than 45 days.

I pick A. Major crops don't work, this doesn't mean that minor will not work. So rye may still work for minor crops.

It should be option D and not A because we are talking only about the major crops and rye's impact on that and not about the minor crops. Option A talks about minor crops whereas the stimulus is about only major crops.

(B) identify any alternative method of weed control that could be used instead of the method it rejects
The stimules says that sowing rye in the fall and ploughing it into the soil can help in controlling broadleaved weeds .
Could an alternative method of weed control mean using rye in a different way ie instead of sowing in the fall, doing something else to the rye and ploughing it into the soil

The conclusion states that : plowing rye into the soil can play no part in effective weed control.
the answer should be D because plowing rye can be used for 45 days and after that synhetic herbicides can be used once the crop grows.Hece when the two weed control method will work
