While researching a thesis paper on ronald reagan’s presidency you discover multiple resources that support your argument. which resource would be the most valid and reliable

The correct answer is:

a. A newspaper reporter who covered the Reagan presidency.

I believe a newspaper would be the most reliable source of information, because newspaper reporters tend to be subjected to higher standard of journalism. Even though it's true that bias would still exist depending on the journalist who wrote the coverages, they are the most trusted sources compared to other people in the options above.

Common Sense by Thomas Paine.

Explanation:

Thomas Paine was a very prominent figure during this time, he encouraged many people to stand up against Great Britain and want independence because of his literary works, primarily Common Sense.

Before Paine became a writer, he failed at almost everything he tried. He dropped out of school and lost many jobs, then he met Benjamin Franklin who encouraged Paine and gave him hope. He eventually moved to the colonies and became a magazine editor, but after the Battle of Lexington, he became very passionate about the colonies declaring their independence from Great Britain.

Common Sense was very long, but was easily worded and revolved around "facts and common sense", that made many people care to read it. It talked about how the colonies need to wake up and have their independence, as they were not being treated fairly by Great Britain. Common Sense sold a ton of copies and many people credit it for inspiring the colonists for supporting their own independence.
