do not answer, if you do not know. i will not tolerate "i don't know".

Correct two answers which are secondary sources:

The other items listed are all primary sources.

Primary sources are things that come from persons directly involved in the events or lives being studied.  So, any diary entries or letters (like the diary of Anne Frank or a letter by a soldier) would count as primary sources.  So would any official proclamations or letters or government documents -- such as the Constitution of France.

Secondary sources are written by historians or others after their study of primary sources.
