description

You should most likely do cause and effect because he wants to understand the reason why world war 1 happened so he would look for the cause

I think it would be a Cause and Effect essay because if George wants to understand the reasons why World War I started, a cause and effect essay will give you the events that took place (effects) and why they happened (causes) which will explain the reasons.
