Q10 - Before their larvae hatch

[tommywallach]

The stimulus tells us two seemingly contradictory facts about a certain kind of beetle:

1) Both parents help to feed the larvae.
2) If one parent is removed before hatching, the larvae end up larger and heavier.

(A) would only make things more confusing, as it provides another benefit of having two parent beetles.
(B) CORRECT. If the parent beetles eat a whole lot of the available food themselves, there might be less available for the larvae.
(C) also makes things more confusing, as there would be no time for rest for the single-parent beetle, implying that it would struggle to keep the larvae fed.
(D) is out of scope. We don’t care when the larvae stop needing the parents.
(E) makes things more confusing again, by providing another benefit to having two parent beetles.
