Passage Summary: Not every bug dies immediately after having offspring; some live quite a while longer. Some of these survivors, like bees, do work that helps the environment.

Reasoning: Some insects live for years after their first reproduction, and some of those long-lived insects, such as bees, provide benefits to the ecosystem.

Analysis: In a 'Must be True' scenario, we are looking for a safe, provable overlap between the categories mentioned. We are told that 'some' insects live past reproduction and 'some' of those survivors benefit the ecosystem. Therefore, we can conclude with certainty that there is at least a subset of insects that both benefit the ecosystem and live beyond their initial reproductive stage. Avoid any answer choices that use overly broad language like 'most' or 'all,' as the stimulus only provides enough evidence for a 'some' statement.
