Logical reasoning PrepTest 146 · Section 1 · Question 1

Correct. Argument or Facts:
Argument/Argument

Valid or Flawed:
Flawed/Flawed

Question Type:
Strengthen (Principle)

Stimulus Summary:
G: We need age info, so we should ask it.

H: We just need age ranges, so we should ask that.

Answer Anticipation:
Hidalgo responds to Grecia's argument by limiting the data that the survey is going to collect—he says that they don't need specific ages, just age ranges. Anything that would justify collecting less data—just enough for what the study requires—will justify his stance.

Answer Explanation:
This answer justifies Hidalgo's stance that the survey should collect age ranges—which is sufficient for the group's purposes—instead of specific ages, so this is the correct answer.

Key Takeaway:
When facing a Strengthen (Principle) question that has two speakers, it can be useful at times to read both to see what the difference is. Here, knowing that Hidalgo wanted to limit the information that was being collected in a way that Grecia didn't would have led directly to the correct answer.

Incorrect. There's no indication that the respondents would lie about their age.

Incorrect. First, there's no indication that age is sensitive. Second, there's no indication that this group can't store their survey information securely.

Incorrect. This answer justifies collecting as much information as might be necessary, not the minimum required. It's almost the opposite of the principle Hidalgo's argument relies on.

Incorrect. There's no indication that Hidalgo doesn't want to inform respondents of how the information will be used, so setting that up as a necessary condition to collecting information doesn't justify his argument.
