Logical reasoning PrepTest 150 · Section 2 · Question 9

Incorrect. The conclusion of this argument isn't about whether Jason is being dishonest, but rather whether what he says is true. If Yu were accusing Jason of lying about using pesticide-free food, then Jason's knowledge would be relevant.

Incorrect. A tempting answer since it suggests Jason is buying pesticide-free foods elsewhere. However, the stimulus has still established that Jason shopped at this store that does sell pesticide-grown food, so this answer doesn't undercut the conclusion that at least some of the food was grown with pesticides.

Argument

Valid or Flawed:

Question Type:

Stimulus Summary:
Jason buys his restaurant's produce from a store that sells produce grown with pesticides. So Jason's Restaurant must serve at least some food that contains products grown with pesticides.

Answer Anticipation:
The stimulus here includes a lot of extra information that can be removed when analyzing the argument, and the conclusion should be rephrased to reflect the idea it refers to. Once we strip out the additional words, it's a lot easier to analyze the logic. Here, just because this store has produce that was grown with pesticides doesn't mean Jason is buying it. They could also have an organic section, and Jason shops there.

Answer Explanation:
This answer choice establishes two things. First, Kelly's carries products grown without pesticides. Second, if someone is interested in buying only those products, they'd have a means of doing so. While this doesn't establish that Jason does avoid pesticides, it establishes that he can while still shopping at this store that carries foods grown with pesticides, and it therefore undermines Yu's claims.

Key Takeaway:
When a conclusion refers to an earlier idea, be sure to rephrase it so you understand the substance of what it's saying.

Incorrect. Yu's claim is that Jason uses at least some foods grown with pesticides, not whether he uses pesticides are approved or safe. This answer is out of scope.

Incorrect. Yu's claim is about what Jason actually does, not what he intends to do. As such, this answer about what people know is out of scope.
