Use the short answer question type to create a fill-in-the-blank question. You can add fill-in-the-blank questions to a publisher-supplied quiz, such as the summative quizzes that you'll often find at the the end of chapters, or to quizzes that you create from scratch.
If you're creating a quiz from scratch, start from your home page and go through the usual steps to add a new quiz. Enter any information you'd like into the Basic Information and/or Settings tabs. When you're ready, proceed to the Questions tab.
If you're adding a question to a publisher-supplied quiz, open the quiz from your home page and select Questions from the Edit drop-down menu.
