Closed Questions
Closed questions invite a short, focused answer. Answers to closed questions can 
often (but not always) be either right or wrong. Closed questions are usually easy 
to answer, because the choice of answer is limited. They can therefore be used 
effectively early in conversations to encourage participation and are useful in fact-
finding scenarios such as research.
Closed questions are used to force a brief, often one-word answer.
Closed questions can simply require a “Yes” or “No” answer, for example: 
“Do you smoke?”, “Did you feed the cat?”, or “Would you like a cup of tea?”
Closed questions can also require that a choice is made from a list of possible 
options, for example: “Would you like beef, chicken or the vegetarian option?”, or 
“Did you travel by train or car today?” Closed questions can be asked to identify 
a certain piece of information, again with a limited set of answers, for example: 
“What is your name?”, “What time does the supermarket open?”, “Where did you 
go to university?”
