Stimulus

Tony: A new kind of videocassette has just been developed. It lasts for only half as many viewings as the old kind does but costs a third as much. Therefore, video rental stores would find it significantly more economical to purchase kind of videocassette than on the old kind.

Anna: But the videocassette itself only accounts for 5 percent of the price a video rental store pays to buy a copy of a movie on video; most of the price consists of royalties the store pays to the studio that produced the movie. So the price that video rental stores pay percent, and royalties would have to be paid on additional copies.

Answer choices

  1. Unsupported: Excessively Large4% picked this

    The royalties paid to movie studios for movies sold on videotape

    Anna doesn't offer any premises to suggest that the royalty fee is excessively high. She is only saying that royalties are way bigger than the cost of the cassette in order to make her fiscal point that switching to the new tape wouldn't save money.

  2. Too Strong2% picked this

    Video rental stores should always stock the highest-quality videocassettes available, because durability is more

    Too Strong: Always / Highest Out of Scope: More Important / Should Anna isn't speaking to highest-quality available. She's just comparing the cost of the currently-used type of cassette to the cost of these new ones. We don't know if the currently used type is the highest-quality. She's also not saying we should use the old type because "durability is more important than price". She's suggesting we should use the old types because "the price is lower!"

  3. Inference, Not Main Conclusion20% picked this

    The largest part of the fee a customer pays to rent a movie from a video rental store goes toward the royalties the

    We can infer that this is true from Anna's first sentence, but this answer's idea is really just a premise to support her main conclusion, which is, "Tony -- you're wrong. Switching to the new cassette wouldn't save money overall."

  4. Correct71% picked this

    The cost savings to video rental stores that buy movies recorded on the cheaper videocassettes rather than movies recorded on the more durable

    Why this is right

    This is a pretty weak version of what the correct answer could have sounded like, but it's still the best available answer in terms of saying, "Tony, you're wrong --- switching to the new cassette would not save money." She is supporting this rebuttal by explaining that the savings you'd get by switching would be small or nonexistent since most of the cost of a copy of a movie is a royalty paid to the studio, and since the new tapes wear out in half the time, you'd be paying that royalty more frequently.

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

  5. Out of Scope: Rental Fee4% picked this

    If the price a video rental store pays to buy a movie on videocassette does not decrease, the rental fee the store charges

    Neither Anna nor Tony speak about the rental fee changing at all, so it doesn't seem like her conclusion is structured to lead to any claim about the rental fee.
