PrepTest 154

Incorrect. Rhett states that Otto expects Otto to pay, and Barbara doesn't speak to the specific situation between Rhett and Otto at all, so this answer is out of scope.

Correct. Argument or Facts:
Argument/Argument

Valid or Flawed:
Flawed/Valid

Question Type:
Point at Issue

Stimulus Summary:
R: Picking me up doesn't cost Otto anything, so I shouldn't have to pay him for gas.

B: By that logic, you're entitled to unused hot air in my house if you can get it without costing me anything.

Answer Anticipation:
Barbara's response to Rhett is a classic method of reasoning—a reductio ad absurdum, or using his logic to reach an absurd conclusion, highlighting that this argument isn't a good one. By rebutting the "flawed logic" of Rhett's argument and showing that his conclusion is absurd, Barbara commits to believing that Rhett's conclusion is wrong and he should pay Otto for gas. Which is good news, because, otherwise, they don't have any overlap in the actual content of their arguments!

Answer Explanation:
Rhett's conclusion is that he shouldn't have to help pay for Otto's gas. Barbara, in rebutting his argument by pointing out how flawed it is, is committed to believing that he should. This is the point at issue between them.

Key Takeaway:
Pointing out an analogous situation that leads to an absurd conclusion—rebutting an argument with a reductio ad absurdum—doesn't create a lot of overlap between the initial argument and the rebuttal. In a Point at Issue question, that pretty much leaves you with the conclusion of the initial argument as the only potential correct answer.

Incorrect. Rhett disagrees with this, but Barbara doesn't speak about the situation between Rhett and Otto, so this answer is out of scope.

Incorrect. Rhett doesn't speak to the situation Barbara describes. While Barbara believes that Rhett's logic commits him to that conclusion, it doesn't mean that Rhett himself would agree.

Incorrect. Rhett doesn't speak to the situation raised by Barbara, and Barbara raises that as a thought experiment, not something that could be turned into reality.
