Answer:
The newspaper on Edgar Allan Poe's poems,
a student's research paper on the civil war,
and an article analyzing Shakespeare's plays.
Step-by-step explanation:
Those 3 are secondary sources.
Ronald Dahl's 'Matilda' was a movie of his own. A journal is from someone personally. A president's autobiography was written about themselves, so they'd know everything about themselves. The other 3 are someone else writing about something that never happened to them personally.
