Answer:
a book written about an event that happened 100 years ago
Explanation:
if the speech from the famous person was at the time of the event and was given by a relatively trustworthy person, then that is a primary source
the journal is considered a primary source because it was written in the time period and by someone who lived in that period
a book wasn't written in the time period, so it isn't completely trustworthy, so it's a secondary source
