The period before we have written records is called prehistory. a. true. b. false

That statement is true

History refer to the study of human affairs that happen in the past based on written evidence that we found.
'Pre' in the word prehistory mean 'before'. So it could be concluded that prehistory is a period when before we have written records, (around 3500 B.C)

hope this helps

Militarism is the answer.
