In a paragraph, explain why the data presented is different, and evaluate the reliability of each source. which should be used in a school research project, and why?

In this question, there is no data or sources presented. Because of this, we cannot successfully evaluate the differences or the reliability of these items. However, we can still talk about the subject of reliability in general terms.

A source that is reliable is one that can be trusted. In order for a source to be trusted, it needs to have earned some reputation as an expert. This can refer to an author, but it can also refer to a group of people, such as a governmental organization. Moreover, a reliable source is one that provides evidence for all the claims it makes. Finally, a reliable source should take into account counterarguments and other types of opposition to the argument the source makes.
