Answer Anticipation

The stimulus here brings up three things true of poppy seeds - mainly, the effects of various things that can happen to one.
The first effect is when it’s pollinated - a substance is released, which causes wilting. And when it’s not pollinated, that substance isn’t released, and it doesn’t wilt until it runs out of nutrients or a week or more passes.
Finally, we learn that when the flower is cut, it releases the same substance as when it’s pollinated. However, it’s silent as to the flower wilting! Can we draw any inference from this?
We can. We know that the substance released when the poppy is pollinated causes it to wilt. So if that same substance is released when it’s cut, then doing so will also cause it to wilt.
Since this inference fills in the missing piece of the information about the poppy, it’ll likely be the correct answer.

Answer choices

  1. A
    Pollinating insects are not Remaining source text redacted.
    Why choice A is not credited
    Petals attract pollinating insects, but there’s no indication that wilted petals don’t have the same effect.
  2. B
    Even if cut poppies Remaining source text redacted.
    Why choice B matches the stem
    This answer matches our anticipation. Cut poppies release the same chemical that pollinated poppies do. That chemical causes pollinated poppies to wilt within a few days, so the cut poppies should do the same, as this answer states.
  3. C
    Flowers of all plants Remaining source text redacted.
    Why choice C is not credited
    This answer is too broad in talking about “all plants.” The stimulus mentions only one plant - the poppy.
  4. D
    The pollen on pollinated Remaining source text redacted.
    Why choice D is not credited
    This answer is way too specific on how pollinated poppies end up wilting, especially since we know the chemical that the poppy releases when pollinated is responsible for the wilting, not the pollen.
  5. E
    Poppy plants are unable Remaining source text redacted.
    Why choice E is not credited
    The flowers wilt, and we know that nutrients can be related to that wilting, but there's no way to know whether the chemical works by preventing the absorption of nutrients from the soil/water. It could just directly cause the wilting!
