If you are writing an analytical/compare and contrast paper, or an argumentative persuasive essay, then you will require research evidence to support your argument.
How much research you will need to do will depend on:
Your existing knowledge;
Your knowledge gaps; and
Any specific requirements outlined by the assignment (e.g. sometimes instructors will require a minimum number or type of sources to be used.)
Research as inquiry
Here are some questions to think about (or ask yourself) when trying to figure out the scope of your research inquiry. Creating a concept map, or brainstorming what you already know about a topic, can help you to identify areas you may want to explore further.
