Question Type:
Flaw
Stimulus Breakdown:
Conclusion: My pesticides are NOT running off into my neighbor's farm.
Evidence: I only use organic pesticides, which are not harmful. And I'm careful to avoid spraying on my neighbor's land.
Answer Anticipation:
Has the author convinced us that her pesticides aren't spreading to her neighbor's farm via runoff water? Not even close, since she never even discussed runoff water. Whether the pesticides are organic or not, harmful or not, has nothing to do with whether or not the pesticides are spreading in runoff water. And spraying pesticides is also beside the point. We're talking about runoff water: as the water rolls down to the lowest point, it runs off somewhere. Does that somewhere include the neighbor's farm? Our main complaint is simply that the author never once addresses runoff water.
Correct Answer:
C
Answer Choice Analysis:
(A) No. This is a famous flaw: Unproven vs. Untrue. The author DOES mention a lack of evidence that OP's are harmful, but the author never concludes (or needs to conclude) that OP's are thus harmless.
(B) No. The author doesn't need to make a quantitatively precise assumption like "usually". The author is definitely thinking that in HER case, being careful to avoid spraying on her neighbor's land is resulting in successfully avoiding her neighbor's land. But additionally, the issue of whether the author's spraying is/isn't getting on the neighbor's farm is immaterial. The issue the conclusion takes on is whether runoff water is/isn't spreading pesticides.
(C) Yes. The author never once addresses the claim about runoff water.
(D) No. Who's to say that there ARE pesticides on the neighbor's land? Why would we demand that our author explain something that we don't even know factually exists?
(E) Would this weaken? No. The issue being debated is not whether pesticides have harmful effects, it's whether pesticides are spreading via runoff water.
Takeaway/Pattern: We don't categorize this flaw as one of the Famous Flaws, but you could definitely find many examples in the history of Flaw questions where it really just comes down to, "What the heck does your evidence have to do with what you're trying to prove?"
