Which of the following is a secondary source? Question 2 options:

a speech from a famous person

a journal from a person who lived during the time period

a book written in 2015 about an event that happened 100 years ago

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
