Bunuel
The argument claims that no-till farming is sufficient for maintaining soil health, as evidenced by studies showing farms using no-till farming report better soil health. To weaken this, we need to identify something that undermines no-till farming as sufficient or points to a dependency that was overlooked.
Answer Choices:
(A)
This discusses the continued recommendation of traditional plowing methods, but it does not challenge the idea that no-till farming improves soil health. It merely highlights a contrasting view without addressing the evidence for no-till farming.
Does not directly weaken the argument.
(B)
This highlights that combining no-till practices with traditional tilling produces even better results. However, this does not disprove that no-till farming alone improves soil health, which is the crux of the argument.
Only partially weakens the argument.
(C)
This states that no-till farming often requires high-tech agricultural machinery to manage crop residue. This directly challenges the sufficiency of no-till farming alone because it suggests that no-till farming cannot be implemented effectively without high-tech machinery. If high-tech machinery is still necessary, then the claim that no-till farming alone is sufficient is undermined.
Strongly weakens the argument.
(D)
While funding bias could undermine the credibility of the studies, it does not directly challenge the effectiveness of no-till farming or address whether it is sufficient for maintaining soil health.
Weaker than (C).
(E)
This would point to a flaw in studies favoring tilled and chemically treated soils, but the question is about no-till farming. This is irrelevant to the sufficiency of no-till practices.
Does not weaken the argument.
Correct Answer:
(C) Farms using no-till farming often require high-tech agricultural machinery to effectively manage crop residue, which is not removed by tilling.
This directly weakens the claim that no-till farming alone is sufficient.
