Multiple-choice questions are designed to test a wide range of reading skills. The questions may require you to skim in order to have an overall understanding of the main idea of a passage, or they may ask you to have a detailed understanding of particular points about which you will need to scan for specific details.
There are two types of multiple-choice questions. The first type is standard multiple choice, which is the most typical form with one question and four possible answers. Specifically speaking, you have to choose one correct answer from the four alternatives given in the question. Another form is known as modified multiple-choice, which requires you to choose more than one out of several options given for a question.
