Question Type:
Weaken
Stimulus Breakdown:
Premise: During the last year the price of produce has spiked.
Premise: During the last year the two largest retail seed companies saw a 19% increase in sales.
Conclusion: Increases in the price of produce have caused an increase in the planting of personal gardens.
Answer Anticipation:
This argument presents a Correlation vs. Causation flaw. If produce prices and seed companies’ sales both increase at the same time, it does not prove that one caused the other. We’ll keep an eye open for answers that suggest an alternate cause, or an answer that indicates the causality is reversed.
Also notice that the increased planting of personal gardens is a new idea in the conclusion. It wasn’t mentioned in the premises. We don’t know that the increase in seed company sales actually resulted from the planting of personal gardens.
Correct answer:
(E)
Answer choice analysis:
(A) Doesn’t address conclusion: This answer only explains why produce prices have increased. It doesn’t address the relationship between produce prices and personal gardens.
(B) Out of scope/Opposite function: This answer does involve produce prices and personal gardens, but the size of the gardens isn’t clearly relevant. If gardens are smaller now, that might help explain why an increase in produce prices would cause an increase in the planting of gardens. But this would strengthen the argument, not weaken!
(C) Doesn’t address conclusion: If there are waiting lists to rent garden plots, it might mean that the gardens are full, which could explain why seed company sales have increased. However, this doesn’t weaken the idea that produce prices are what led to an increase in planting of gardens.
(D) Out of Scope: The argument doesn’t discuss an economic downturn, and there isn’t a clear connection between a downturn and our argument.
(E) Correct: This challenges the idea that our evidence, the increase in seed company sales, was caused by an increase of the planting of personal gardens. If a large seed company went out of business then people could be buying the same amount of seeds, but with fewer companies selling them. The remaining companies would see an increase in sales without any more gardens being planted. There might not have been an increase in gardens being planted, much less one caused by an increase in produce prices.
Takeaway/Pattern:
We don’t have to accept any part of an argument’s conclusion as true. The premises are supposed to convince us that the conclusion is true. When an argument leaves several gaps between the premises and the conclusion, the answer to a Weaken question might attack any of those gaps.
