Answer:
An author's<em> </em><u><em>point of view</em></u> describes the author's perspective or relationship to the material.
An author's <em><u>purpose</u></em> tells why he or she created the source.
Identifying an author's point of view and purpose can help a historian determine whether a source is <em><u>credible</u></em>.
Explanation:
An author's point of view refers to the perspective that an author has on the world or on the subject that he is discussing. This is usually influenced by the author's background and his experiences in life. On the other hand, the author's purpose refers to the reason or motivation why the author writes a particular text. When historians analyze a text in order to use it as a source, they look at both the point of view and the purpose of the author. These two elements can help the historian ascertain whether the source is to be trusted or not.
