Passage Summary: If you get information from a trustworthy source, it's okay to believe it; furthermore, some of these trustworthy beliefs aren't obvious on their own and aren't based on things you can see for yourself.

Reasoning: Beliefs from reliable sources are reasonable to maintain, and some of these beliefs are not self-evident or based on observable evidence.

Analysis: This stimulus provides a conditional rule and an existential fact. We are told that a reliable source is a sufficient condition for a belief to be reasonable. We are then told that there exists a subset of these reliable-source beliefs that lack self-evidence and observable evidence. By combining these, we can conclude that there are indeed reasonable beliefs that are neither self-evident nor based on observable evidence. Look for an answer choice that simply synthesizes these two premises into a single statement.
