Evaluate
The first sentence was conditional. Whenever we get a Conditional on Must Be True or Most Supported we ask ourselves two questions:
1. Are there any other conditionals that we can chain this up with? 2. Are there any facts that trigger the conditional (or the contrapositive)?
In this case, there isn't any other conditional besides the first sentence. So #1 is not applicable. For #2, we're asking if there were any facts about a "belief based on info from a reliable source" or about "a belief it would be unreasonable to maintain" (because that would trigger the contrapositive).
The last sentence is talking about some beliefs that are based on info from a reliable source, so we automatically know that those beliefs are "reasonable to maintain". Thus, it is likely that they're testing our ability to pair up "reasonable to maintain" with one of the other two traits described in the last sentence.
