Which two sources are secondary sources for an essay on world war ii?
a) "a history textbook on the events of world war ii"
b) "a book about the effects of world war i"
c) "the diary of anne frank (the experiences of a jewish family during world war ii)"
d) "the constitution of france"
e) "a letter written by a soldier who fought the germans"
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.
