Stimulus

Mayor: Periodically an ice cream company will hold a free ice cream day as a promotion. Showing up may not cost you any money, but it sure does cost you time. We learn from this that when something valuable costs no money you get overconsumption and long lines. Currently, those who drive the use of roads during rush hour. Then rush hour congestion will abate.

The question

The claim that when something valuable costs no money you get overconsumption and long lines plays which one of the following roles

Answer choices, explained

  1. Opposite: rejected2% picked this

    It is a hypothesis that is rejected in favor of the hypothesis stated in the

    This claim supports the conclusion, but this answer is saying we reject it en route to our conclusion.

  2. Not Opposing3% picked this

    It is a concession made to those who dispute an analogy drawn

    A concession is the same as granting your opponent a point. It's not in the Support family (premise, illustration, example, subsidiary conclusion, ruling out objection). Also there's no one present disputing the analogy, so we can't match this up with anything.

  3. Wrong Role15% picked this

    It helps establish the importance of the argument’s overall conclusion, but is not offered as

    This isn't a role I've ever seen tested as a correct answer. It seems to describe a piece of background that would set the context for the argument. For example, "Global warming is the most important problem facing humanity. We should switch to a vegetarian diet; after all, eating meat is one of the behavior that adds the most to global warming." At any rate, the claim we're being tested on was definitely offered as evidence for the conclusion that we should charge a toll for driving on the road at rush hour.

  4. Correct73% picked this

    It is a general claim used in support of the argument’s

    Why this is right

    It is indeed a general claim (it's phrased as a broad takeaway from the ice cream example) that serves as a principle underlying the author's suggestion. Since "not being charged for something valuable leads to overcrowding", the author thinks that "charging for rush-hour road use will lessen overcrowding".

    Skill tested: Role · how this choice captures the argument's function is the move to repeat next time.

  5. Wrong Role7% picked this

    It is the overall conclusion of

    The conclusion is the "What is needed is a system for charging to use the road during rush-hour", and the claim we're being asked about is the biggest supporting reason for why the author thinks we need that system.
