For pollinating certain crops such as cranberries, bumblebees are far more efficient than honeybees.

Information

Comparison (far more efficient)

Bumblebees are more efficient than Honeybees, when it comes to pollinating cranberries and certain other crops.

Causal Difference-Maker: this is because

Comparison (broader area / wider variety of species)

Honeybees visit a broader area and visit a wider variety of species

Goal

Since there was Causal Difference-Maker language like "This is because", we would assume that the correct answer is going to reinforce the connection between the two things we know about bumblebees and honeybees. It's the ol' One Difference Explains the Other Difference.

Said from the point of view of bumblebees: visiting only a few species over a limited area makes you a more efficient pollinator for certain crops (such as cranberries)

Said from the point of view of honeybees: visiting a wider variety of species over a broader area makes you a less efficient pollinator for certain crops (such as cranberries)

20.

Which one of the following is most strongly supported by the information above?

  1. If a honeybee visits a

    Too Strong

    Too Strong: any one of those species The pollinating advantage we were told about for bumblebees is only for certain crops. So we can't support this overly strong blanket statement that for some unknown variety of crop, the honeybee will be worse at pollinating each one of those crops.

  2. Correct

    The number of plant species

    Why this is right

    This reinforces the causal difference-maker: when it came to cranberries, we knew that honeybees were far less efficient pollinators than bumblebees, because honeybees visit a wider variety of species (over a broader area). So it's fair to say that "visiting a wider variety of species affects how efficient you are as a pollinator". Another way of saying that the honeybee visits a wider variety of species than the bumblebee does is to say, "the honeybee visits a higher number of plant species other than cranberries than the bumble bee does". If anyone was disliking this answer because it only reinforces the number of species visited, not the broadness of area flown over, I agree it's not perfect. But this is Most Supported. And the answer is just saying "affects", which is super weak.

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

    Too Strong

    Too Strong: the more x, the less y Unknown/Opposite Relationship This seems counterintuitive. The more area a bee flies over, the smaller number of species they can visit? Expanding the area you fly over could only ever add to the number of species that you are able to visit. Beyond the fact that this seems internally contradictory, the paragraph doesn't give us any support for this super-strongly worded relationship between broadness of territory and number of species one can possibly visit.

  4. Cranberries are typically found concentrated

    Too Strong: typically

    This is trying to rope together a lot of familiar wording from the paragraph, but we don't have any support for the idea that at least 51% of the time, cranberries are found in limited areas that are more likely to be visited by bumblebees than by honeybees. This paragraph is compatible with the notion that honeybees visit cranberries way more often than bumblebees ever do. All it's telling us is that B's are more efficient pollinators of cranberries, not that they are more frequent visitors.

  5. The greater the likelihood of

    Too Strong

    Too Strong: the more x, the more y Unknown Relationship The causal difference-maker, if put into this "the more x, the more y" format, would sound like this: The fewer species and smaller range of territory visited by a given bee species, the more efficient that bee species will be at pollinating cranberries. This answer makes it seem like we talked about "how likely" it is for a bumblebees or an honeybees to visit a cranberry crop, which we did not.
