Free response, usually referred to as essay, is a type of question used in tests in education, workplace, and government. Most free response questions ask or require the test-taker to state a belief, opinion, or write a short essay and support it with facts, examples, or other evidence. However, few tests solely rely on these types of problems, and tend to work in conjunction with other types, such as multiple choice. Free response questions generally test more than straight knowledge and ask for a "big picture" type of response (see example). Also, they usually allow the taker to choose an area in which they are familiar.
