Stimulus

Advertisement: The Country Classic is the only kind of car in its class that offers an antilock braking system that includes TrackAid. An antilock braking system keeps your wheels from locking up during hard braking, and TrackAid keeps your rear wheels from spinning on slippery surfaces. So if you are a safety-conscious class, the Country Classic is the only car for you.

The advertisement is misleading if which one of the following

Answer choices

  1. Weak Impact10% picked this

    All of the cars that are in the same class as the Country Classic offer some kind

    The first sentence already suggests that other cars in its class have antilock braking systems; the first sentence is saying that what makes Country Classic special is that its antilock system includes TrackAid.

  2. Weak Impact3% picked this

    Most kinds of cars that are in the same class as the Country Classic are manufactured by the same company

    If most cars in the same class as Country Classic are made by the same parent manufacturer, it makes that class of cars sound less diversified, and possibly suggests that there aren't that many cars in that class to begin with. The fewer cars there are in the Country Classic's class, the less impressive it is to boast that it's the leader of the class or the only car in its class with X. (I used to tell people how I graduated at the top of my class, for Philosophy. I'd let them be impressed and then tell them, "there were only 8 of us", to then comically diminish the accomplishment)

  3. No Impact4% picked this

    Without an antilock braking system, the wheels of the Country Classic and other cars in its class are more likely to lock up during

    This is a fact that makes antilock braking systems sound valuable, which was the intended effect of the commercial, so this doesn't point to anything misleading. The commercial was trying to make TrackAid seem special/important, and TrackAid dealt with preventing wheels from spinning on slippery surfaces. This answer makes that threat seem like the smaller of two threats, so we might think diminishing the threat of spinning on slippery surfaces diminishes the importance of TrackAid. But as long as spinning on slippery surfaces is a threat, the commercial can still say we get some safety benefit out of having TrackAid, in addition to what standard anti-lock brakes do.

  4. Correct82% picked this

    Other cars in the same class as the Country Classic offer an antilock braking system that uses a method other than TrackAid to prevent

    Why this is right

    The commercial was trying to make the Country Classic sound like it was special / safer, because it was the only car in its class with TrackAid, which prevents rear slipping. But this answer would allow us to object, "Sure, the Country Classic might be the only car in its class with TrackAid, but it's not the only car in its class that prevents rear wheels from spinning on slippery surfaces. We don't use TrackAid, but we have SlipNot, which does the same thing."

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

  5. Irrelevant: expensive1% picked this

    The Country Classic is more expensive than any other car in

    The fact that the Country Classic is the most expensive car in its class might be an idea that would weaken a conclusion saying, "You should buy the Country Classic". But we weren't asked to weaken the conclusion. We were asked for something that would make the advertisement seem misleading (i.e. what is says is technically true, but it sends the wrong message). The argument never talked about anything relating to cost, so it couldn't have misled when it comes to how expensive the Country Classic is.
