Answer:
The correct answer is "It includes factual information supported by other sources"
Step-by-step explanation:

For instance, a scientific article or a book has its own references as well; while reliable webpages such as the ones that are administrated by the government (.gov) have their sources of information that come from institutions or other articles.
