Which 2 statements indicate the reliability of a secondary source?

Cites sources and presents information in an unbiased manner.

expresses some positive opinions about a well liked historical personality

presents factual information in a clear and accurate manner

Cites sources and presents information in an unbiased manner.

presents factual information in a clear and accurate manner

Explanation:

If you must use a secondary source (as in, a source that is not directly connected to know), the least you can look for is a source that has a history of being unbiased, factual, transparent and accurate. In that way, at least, you can consider how trusted can the source be. When a source expresses strong opinion about something, most likely it's very biased and has a goal behind presenting information.

The first and the last indicate it's a reliable source.
