Passage Summary: Lemurs in two different forests both become more active at night during the winter, but the ones in the forest where trees lose their leaves show a much larger shift to nighttime activity.

Reasoning: No conclusion (Fact Set).

Analysis: The paradox here is the difference in magnitude: why do the deciduous forest lemurs go 'more nocturnal' than the rain forest lemurs? The stimulus provides a huge hint by mentioning that deciduous trees lose their leaves in winter while rain forest canopies stay consistent. To resolve this, we need a reason why losing leaves would make daytime activity less desirable or nighttime activity more necessary. Look for an answer that links the lack of leaf cover to a factor like predator visibility or temperature regulation.
