Passage Summary: Usually, having two parents to feed you is better than one. However, with these beetles, if you remove one parent, the babies actually grow up to be larger and heavier than if both parents stayed.

Reasoning: No reasoning (Fact Set).

Analysis: The paradox here is that 'more help' (two parents) leads to 'less growth' (smaller larvae). To resolve this, we need a piece of information that explains why the presence of a second parent is actually a net negative for the larvae. Perhaps the parents compete with the larvae for the food source, or maybe the presence of two adults leads to more energy spent on social interaction rather than feeding. Look for an answer that introduces a hidden cost of having both parents present that outweighs the benefit of the extra labor.
