The question
16.

Which one of the following, if true, most seriously weakens the company

Answer choices

  1. No Impact32% picked this

    Only 1 percent of the automobiles driven in the local area

    That's fine, but it doesn't change the fact that those old cars are still 30% of the local air pollution. If anything, the fact that these old cars are only 1% mean that it's more feasible for us to buy them all up (which would strengthen).

  2. Irrelevant: cost Opposite3% picked this

    It would cost the company over $3 million to reduce its plants' toxic emissions, while its car-buying campaign will save the company money by

    We don't care about money at all. We're only measuring the impact on air pollution, but this answer should be very un-tempting since it argues in favor of doing the car buying idea.

  3. Correct53% picked this

    Because the company pays only scrap metal prices for used cars, almost none of the cars sold to

    Why this is right

    This answer is saying that the people who seem willing to take part in this program are almost always people with an old car they don't drive (you know that neighbor with an old car in the garage or up on blocks). Buying those cars is irrelevant to air pollution, because those old cars weren't on the road. We WANT to be buying the old cars that people are still driving around, spewing noxious exhaust everywhere. But "almost none" of those people are selling us their cars (presumably because they need those cars as transportation, and company is offering so little money in this buyback program that someone who sold their old car wouldn't get enough money to then buy a newer one)

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

  4. Irrelevant: post-1980 cars11% picked this

    Automobiles made after 1980 account for over 30 percent of local

    Cool fact, choice (D). Unfortunately, this has nothing to do with comparing the two options that are relevant to the conclusion: redesigning plants vs. buying pre-1980 cars.

  5. Irrelevant: complaints1% picked this

    Since the company launched its car-buying campaign, the number of citizen groups filling complaints about pollution from the

    We're only measuring these two options in terms of which one reduces air pollution more. Public perception of how much we've reduced air pollution is irrelevant (sort of like the Famous Flaw Inappropriate Appeal to Opinion).
