input with options: Answer the following question given this paragraph: Plants have specialized organs that help them survive and reproduce in a great diversity of habitats. Major organs of most plants include roots, stems, and leaves. Leaves are the keys not only to plant life but to all terrestrial life. The primary role of leaves is to collect sunlight and make food by photosynthesis . Despite the fundamental importance of the work they do, there is great diversity in the leaves of plants. However, given the diversity of habitats in which plants live, it's not surprising that there is no single best way to collect solar energy for photosynthesis. Q: The primary role of leaves is to collect what? A:
OPTIONS:
- pollen
- insects
- precipitation
- sunlight
output:
sunlight
