Which three sources are examples of secondary sources? a newspaper article on edgar allan poe’s poems ronald dahl’s matilda a students research paper on the civil war a journal article analyzing shakespeare’s plays a president autobiography of his life

The newspaper on Edgar Allan Poe's poems,

a student's research paper on the civil war,

and an article analyzing Shakespeare's plays.

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.

usually, a falcon can kill an owl, and horses don't normally eat each other.
