Stimulus Summary

H: Honeybees use scent to tell other bees how to get to food, so they don’t need to use dancing and there must be some other explanation for it. W: Most animals have more than one way to do something, like some bees that use both the Sun and landmarks to navigate, so the honeybees could use both dance and smell to leave trails to food.

Answer Anticipation

For this question, we’re dealing with what Winifred has to say. And we’re looking to describe the role of the statement about the species that navigate using either the Sun or landmarks. This statement comes right after the claim that most animals have multiple ways of doing critical tasks. How do the two statements intersect? Well, the statement in question is a species that has multiple ways to navigate - which certainly counts as a critical task. So the statement in question is an example that backs up a general claim. We’re not done, though - how does that general claim work in the argument? It’s a part of the rebuttal, serving as a general proposition that is then used to argue that the honeybees might have multiple ways to communicate how to get to food. Let’s find an answer reflecting this argument structure!

Answer choices

  1. A
    It addresses an ambiguity Remaining source text redacted.
    Why choice A is not credited
    There’s no ambiguity - it means telling other bees how to get to food. If there is an ambiguity, it’s in how they do it, not what the goal is.
  2. B
    It provides evidence in Remaining source text redacted.
    Why choice B matches the stem
    The bees that use both the Sun and landmarks to navigate is an example that supports the general claim that most animals have more than one way to do important things, making this the correct answer.
  3. C
    It calls into question Remaining source text redacted.
    Why choice C is not credited
    The evidence cited by Henry is that the honeybees leave a scent trail from the food source back to the hive. Winifred says that scent trails are a supplementary means of communicating, implicitly accepting Henry’s premise. So she doesn’t question the accuracy of his evidence!
  4. D
    It points out that Remaining source text redacted.
    Why choice D is not credited
    Henry’s conclusion is that honeybees use dancing for something other than communicating the location of food sources. None of his premises contradict that, and Winifred doesn’t claim that they do.
  5. E
    It proposes an alternative Remaining source text redacted.
    Why choice E is not credited
    Winifred only mentions the dance as a potential way to communicate where food is. That’s the only explanation that Henry offers (even if he doesn’t think it’s the correct one), so this answer is also incorrect.
