Which type of writing assignment would benefit most from the use of outside sources such as scholarly works or reference works

The writing assignment would be an argumentative essay because in this type of essay most often you would support your claim by backing your claim up with various sorts of evidence, for example if you are arguing to what extent does Sea World mistreat animals, you would back your claim up by using scholarly works or reference works of articles that display the mistreatment of animals. Hope this helps you.
