Premise: Extensive use of high-tech agricultural machinery is essential for maintaining soil health.
Counter-premise/conclusion: Simply adopting no-till farming, which minimizes the disturbance of soil, is sufficient because there are studies indicating that farms using no-till practices consistently report better soil health.

=> To weaken is to remove support for the conclusion that no-till farming is enough to maintain soil health, aka discredit the studies.

=> IMO: E

Ans: D. The studies assessing soil health on farms using no-till practices were funded by manufacturers promoting high-tech farming equipment, potentially biasing the results

Statement: Farms using no-till practices consistently report better soil health
Ask: Weaken the force of the evidence cited

(A) Many agricultural scientists continue to recommend traditional plowing techniques alongside modern machinery to prevent soil compaction and maintain fertility
This statement mentions that traditional methods with modern machinery is recommended by the agricultural scientists. This does not weaken the statement as we need to prove that no-till practice does not report better soil health. Maybe the combination of both brings out the best results but no-till method alone can be good too. Eliminate.

(B) Farms that combine no-till practices with traditional tilling methods report the highest levels of soil fertility and overall health
This mentions that no-till practices with traditional tilling methods report the highest levels of soil fertility and overall health but maybe soils which are not tilled show great results as well even if it is not the best. Eliminate.

(C) Farms using no-till farming often require high-tech agricultural machinery to effectively manage crop residue, which is not removed by tilling
This statement talks about the crop residue and not the health of the soil in general. Eliminate.

(D) The studies assessing soil health on farms using no-till practices were funded by manufacturers promoting high-tech farming equipment, potentially biasing the results
This statement calls into question the soils used for the study. If the soil was taken from farms which are funded by manufacturers promoting high-tech farming equipment then we cannot be sure that high-tech farming equipment was not used to improve the soil health. This is our answer.

(E) The metrics used to assess soil health in the studies are typically those that favor soils which have been recently tilled and chemically treated
This strengthens the statement as the metrics favor soils that have been recently tilled and chemically treated and even then the soil which was not tilled showed great results. Eliminate.

The correct answer is D

(A) Many agricultural scientists continue to recommend traditional plowing techniques alongside modern machinery to prevent soil compaction and maintain fertility. - This supports the argument - Out

(B) Farms that combine no-till practices with traditional tilling methods report the highest levels of soil fertility and overall health. - This supports the argument - Out

(C) Farms using no-till farming often require high-tech agricultural machinery to effectively manage crop residue, which is not removed by tilling. - It talks about using high-tech agricultural machinery to manage crop residue effectively and does not talk about soil health - Out

(D) The studies assessing soil health on farms using no-till practices were funded by manufacturers promoting high-tech farming equipment, potentially biasing the results. - This seriously weakens the argument. If studies assessing soil health give biased results, then the evidence cannot be relied upon - Keep

(E) The metrics used to assess soil health in the studies are typically those that favor soils which have been recently tilled and chemically treated. - Out of context - Out

Question type:

Weaken

Here we have to weaken the force of evidence (i.e. the study) used in proving the conclusion, this is different than actual weakening question where we targeted the assumption.

Answer choice analysis:

A. Many agricultural scientists continue to recommend traditional plowing techniques alongside modern machinery to prevent soil compaction and maintain fertility.

Incorrect, While this may weaken the conclusion for a moment this in no way counters the evidence used to establish the conclusion.

B. Farms that combine no-till practices with traditional tilling methods report the highest levels of soil fertility and overall health.

Incorrect, We are concerned only about farms that used no till practices while this may be a BETTER PLAN, it does not make an impact on our argument.

C. Farms using no-till farming often require high-tech agricultural machinery to effectively manage crop residue, which is not removed by tilling.

Incorrect, There is no way we can establish a relationship between crop residue and soil health.


D. The studies assessing soil health on farms using no-till practices were funded by manufacturers promoting high-tech farming equipment, potentially biasing the results.

Correct. If this is true we have less belief on the studies and hence less belief on the evidence used by the argument, which definitely weakens the argument.

E. The metrics used to assess soil health in the studies are typically those that favor soils which have been recently tilled and chemically treated.

Incorrect. This choice goes complete 180 with the evidence If even on applying these metrics the no till practices give better soil health it actually increases our belief in the conclusion that no till practices are sufficient.

D is the answer

To find the weakener for the evidence, let's eliminate one by one -

(A) Many agricultural scientists continue to recommend traditional plowing techniques alongside modern machinery to prevent soil compaction and maintain fertility - Agricultural scientists continuing to promote something doesn't weaken the evidence i.e. the studies - ELIMINATE

(B) Farms that combine no-till practices with traditional tilling methods report the highest levels of soil fertility and overall health - this doesn't weaken the evidence as well as it is a generic thing & not wrt the studies - ELIMINATE

(C) Farms using no-till farming often require high-tech agricultural machinery to effectively manage crop residue, which is not removed by tilling - Same as A & B - ELIMINATE

(D) The studies assessing soil health on farms using no-till practices were funded by manufacturers promoting high-tech farming equipment, potentially biasing the results - This tells us that the studies used for support for the evidence were biased. Hence, weakening the argument - CORRECT

(E) The metrics used to assess soil health in the studies are typically those that favor soils which have been recently tilled and chemically treated - if this was the case then, the tilling practice would be shown as beneficial & not the other way around - ELIMINATE

IMO D

The argument says that: high-tech machinery is good for soil health BUT studies show better soil health on no-till farms => no-till farming is also good

The sought-after weakener would have to somehow detract from how good no-till farms are from soil health perspective.

A. There’s a recommendation to not drop high-tech machinery altogether – this weakens the conclusion, but not the evidence.
Eliminate.

B. No-till is best combined with tilling – but we never heard that no-till is supposed to be ‘best’, it’s just supposed to also be effective.
Eliminate.

C. Even the cited effective no-till farms still need high-tech machinery. This seems to weaken the evidence as it partially invalidates its findings.

D. This would be a strengthener, as high-tech companies would be expected to downplay no-till farming rather than admit its effectiveness.
Eliminate.

E. Potentially, no-till farms reported to be better could be so simply due to previous tilling and chemical treatment, hence it weakens the evidence.

Between C and E, I’m more inclined to choose E as it’s specifically dealing with the study results and soil health. C, however, only weakens the evidence insofar as crop residue management impacts soil health (which seems logical but we don’t actually have confirmed).

Therefore, the answer is E.

  • From the given passage, I concluded it emphasises that using hi-tech machinery is not essential and no-till faming can be used as a substitute to the machines.
  • Option C directly nullifies this conclusion by saying that no-till farming itself requires hi-tech machinery and hence no-till cannot act as a substitute.

Hence, I choose option C.

(A) This presents an alternative approach to maintaining soil health but does not directly refute the evidence that no-till farming improves soil health.

(B) This introduces a combined method (no-till with traditional tilling) but does not contradict the claim that no-till farming alone is sufficient for soil health.

(C) This indicates that high-tech machinery might still be required for no-till farming, but it does not challenge the evidence supporting the effectiveness of no-till practices in improving soil health.

(D) This questions the reliability of the studies by pointing to potential bias in their funding. If manufacturers of high-tech equipment funded the research, the results might not accurately reflect the effectiveness of no-till farming, thereby weakening the evidence.

(E) This raises the possibility that the metrics used to assess soil health may favor recently tilled soils, but it does not directly undermine the evidence supporting the benefits of no-till practices; it merely questions the criteria for assessing soil health.

Opt. D most seriously weakens the force of the evidence cited. SO, D is ans.

Ask : Weaken the evidence that adopting no till farming report better soil health

Options :

A - Scientists recommend both - this doesn't weaken the evidence
B - Farms which use both report best soil health - Doesn't weaken the evidence
C - Farms with no-till need high-tech machinery - which is against the evidence of not using high tech machinery
D - High-tech equipments funding the studies despite the bias for traditional methods(high-tech machinery) shows no-till is better
E - Metrics used in studies were not appropriate for no-till soil and it favours the recently tilled and treated land, meaning even with infavourable metrics no-till land was proven better

OPTION C

A. The discuss is around Modern Machinery and No-Till practices while the point talks about traditional plowing which are not related.
B. The study suggested to use only No-till practice but the point talks about no-till and traditional tilling in combination.
C. This does weaken the evidence cited as it directly talks about the requirement of using high tech machinery along with dependency on high-tech agricultural machinery.
D. The paragraph indicate that no-till is sufficient for the health of soil and we do not require the use of machinery. This does not go well with the point mentioned in the option.

In this question we need an answer that pokes holes on the reliability of no-till practices
From the answers provided only choice C does that by revealing the usage of high machinery with no-till practices which means the overall benefit of no-till practices could actually be as a result of using high tech machinery to manage crop residue

Evidence: Simply adopting no-till farming, which minimizes the disturbance of soil, is sufficient for maintaining soil health on large farms

(A) Many agricultural scientists continue to recommend traditional plowing techniques alongside modern machinery to prevent soil compaction and maintain fertility.
It simply provides an alternative recommendation, but it does not weaken the force of the evidence that no-till farming is sufficient for soil health. INCORRECT

(B) Farms that combine no-till practices with traditional tilling methods report the highest levels of soil fertility and overall health.
This weakens the evidence by indicating that no-till farming alone may not be as effective as combining it with traditional tilling. CORRECT

(C) Farms using no-till farming often require high-tech agricultural machinery to effectively manage crop residue, which is not removed by tilling.
It does not directly challenge the effectiveness of no-till farming for maintaining soil health. It just points out that machinery might still be used. INCORRECT

(D) The studies assessing soil health on farms using no-till practices were funded by manufacturers promoting high-tech farming equipment, potentially biasing the results.
It does not weaken the evidence beacuse, if these studies were funded by manufacturers promoting high-tech farming equipment, the possible bias would be in favor of high-tech farming, and these studies support no-till farming. INCORRECT

(E) The metrics used to assess soil health in the studies are typically those that favor soils which have been recently tilled and chemically treated.
The same as in (D). The possible bias would be in favor of high-tech farming, and these studies support no-till farming. INCORRECT

(A) This option introduces an alternative recommendation, suggesting that traditional plowing might still be necessary to prevent soil compaction. However, it doesn't directly contradict the studies showing that no-till farming improves soil health.

(B) CORRECT
This directly weakens the argument by suggesting that no-till farming alone may not be sufficient and that combining techniques might be better.


(C) This option indicates that no-till farming may still require high-tech machinery for managing crop residue, but it does not challenge the core idea that no-till farming improves soil health.

(D) This option suggests that the studies may be biased due to their funding sources. If the studies were funded by those who have a vested interest in promoting high-tech machinery, the results might be skewed in favor of using machinery. But the studies indicates that farms using no-till practices consistently report better soil health.

(E) If the metrics favor recently tilled or chemically treated soils, they might not be the best indicators for evaluating no-till farming. But despite that, the studies indicate that farms using no-till practices consistently report better soil health.

(C) Farms using no-till farming often require high-tech agricultural machinery to effectively manage crop residue, which is not removed by tilling.

(A) Many agricultural scientists continue to recommend traditional plowing techniques alongside modern machinery to prevent soil compaction and maintain fertility.
This does not address the studies cited or the argument’s claim about the sufficiency of no-till farming. It simply provides another perspective

(B) Farms that combine no-till practices with traditional tilling methods report the highest levels of soil fertility and overall health.
This suggests a better alternative but does not weaken the claim that no-till farming alone is sufficient to maintain soil health

(C) Farms using no-till farming often require high-tech agricultural machinery to effectively manage crop residue, which is not removed by tilling.
This is stronger because it directly attacks the argument’s claim of sufficiency by showing that no-till farming cannot work independently without high-tech machinery. This weakens the core conclusion

(D) The studies assessing soil health on farms using no-till practices were funded by manufacturers promoting high-tech farming equipment, potentially biasing the results.
This statement introduces doubt about the evidence but doesn’t definitively weaken the conclusion itself. We know that biased studies could possibly yield correct conclusions

(E) The metrics used to assess soil health in the studies are typically those that favor soils which have been recently tilled and chemically treated.
The studies still support the argument for no-till farming being sufficient to maintain soil health.
Now, if the evaluation metrics are biased toward tilled soils, and no-till soils still perform better, that strengthens confidence in the conclusion rather than weakening it

It is commonly believed that the extensive use of high-tech agricultural machinery is essential for maintaining soil health on large farms. However, evidence suggests that simply adopting no-till farming, which minimizes the disturbance of soil, is sufficient. This conclusion is supported by studies indicating that farms using no-till practices consistently report better soil health.

Which of the following, if true, most seriously weakens the force of the evidence cited?

(A) Many agricultural scientists continue to recommend traditional plowing techniques alongside modern machinery to prevent soil compaction and maintain fertility.

(B) Farms that combine no-till practices with traditional tilling methods report the highest levels of soil fertility and overall health.

(C) Farms using no-till farming often require high-tech agricultural machinery to effectively manage crop residue, which is not removed by tilling.

(D) The studies assessing soil health on farms using no-till practices were funded by manufacturers promoting high-tech farming equipment, potentially biasing the results.

(E) The metrics used to assess soil health in the studies are typically those that favor soils which have been recently tilled and chemically treated.

Background: It’s commonly believed that the extensive use of high-tech agri machinery is essential for maintaining soil health on large farms.
Premise: However, studies indicate that farms using no-till practices, which minimize the disturbance of soil, consistently report better soil health.
Conclusion: Adopting no-till farming alone is sufficient to maintain good soil health in large farms.

We’re looking to weaken the argument.

A. This is irrelevant. It offers another perspective, but it doesn’t address any assumptions.
B. This is irrelevant, because the conclusion is about good soil health, not the best soil health. No-till farming could still be adequate to maintain good soil health.
C. This weakens the conclusion because if the no-till farms still have to use high-tech machinery, then adopting no-till farming alone would not be sufficient to maintain good solid health.
D. If anything, this strengthens the argument, because the bias it’s vulnerable to would be in favor of high-tech agri equipment, not no-till farming.
E. This has an unclear effect on the argument, but also leans towards strengthening, since the findings still suggested that no-till soil is healthier, despite the studies being designed to favor tilled and chemically treated soil.

Best answer is C.
