Answer choices

  1. No Impact4% picked this

    Few people depend exclusively on apricots and carrots to supply vitamin C

    Whether few people depend exclusively on apricots and carrots for vitamin C doesn't directly address whether apricots and carrots are legitimate examples of good nutrition (or at least good sources of vitamin C). In order for us to be impressed by comparing soup to these foods, we would want to know that these foods are high in nutrients. We don't care about the number of people who consume them.

  2. Too Weak18% picked this

    A liquid can lose vitamins if it stands in contact with the air for a

    A soup is a liquid, and so this is saying that soup can lose vitamins if it's in contact with air for a long time. But who says soup would ever be in contact with air for a long time? Maybe the intent is that you open up its airtight can, warm it up, and eat it. Also, this has nothing to do with the evidence about apricots and carrots or bragging about the soup's superior vitamin C content.

  3. Opposite Impact1% picked this

    Tomato soup contains important nutrients other than

    This answer helps someone argue that soup is nutritious, which is the opposite of our goal. We want to be able to say, "Sure, this soup beats apricots and carrots in terms of vitamin C, but that doesn't mean this soup is nutritious. After all, [answer choice]."

  4. Weaker Impact3% picked this

    The amount of vitamin C provided by a serving of the advertised soup is less than the amount furnished by

    Saying that this soup's vitamin C content loses to that of strawberries is kind of a way to argue that the soup isn't nutritious. This answer is decent, but has less impact than the correct answer (and less relevance to the task of showing how the original evidence was misleading).

  5. Correct74% picked this

    Apricots and fresh carrots are widely known to be nutritious, but their contribution consists primarily in providing a large amount of vitamin A, not

    Why this is right

    The advertisement emphasizes vitamin C content, but if apricots and carrots are known for their vitamin A contribution, it suggests that comparing vitamin C content alone is misleading. This highlights the advertisement's selective focus, taking foods such as apricots and carrots (which are probably thought to be nutritious, since they're fruits and vegetables), but makes the soup seem superior by focusing on a vitamin that isn't a strong suit of apricots or carrots. It'd be like trying to prove that Dave is smart by saying he has won more court cases than Doctor X and Doctor Y. Sure Doctor X and Doctor Y are probably considered smart, but not because of how many court cases they've won (they're not lawyers!). So bragging that Dave has won more court cases than these medical doctors is a pretty hollow brag, just like bragging that soup has more vitamin C content than two foods that don't have much vitamin C is a misleading brag.

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