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.
Even though all of the mentioned options represent secondary sources, as they do not belong to President's Reagan's comments about his presidency, the most accurate or reliable source would be the reporter who covered Ronald Reagan's presidency, as his sole purpose was to follow the President throughout all of his affairs while in office. This reporter will certainly have information with a much greater level of detail in comparison to the other sources, which do not focus solely on President Reagan.
The Proclamation of 1763 was issued by King George II after Britain's victory over France in the French and Indian War and restricted settlers from settling beyond the Appellation Mountains. <span />
