Multiple choice
Multiple choice questions have 2 parts. The first part is called the stem, which is a problem to be solved or a sentence needing completion. The question is usually straightforward (only a few options) and it needs review to get the right answer. The second part, the options, have 2 variations, or differences. The first is called the key, and is the correct answer. The other answers are called distractors. They are usually very close to the actual answer so they can confuse people. Multiple choice questions are used on standardized tests, and they aren't always questions. They may be math equations, incomplete sentences, or other things.
