Open questions leave room for a description or opinion, and are more useful in eliciting information
Open questions are often called Wh.. questions:-
There are eight wh-questions – what, when, where, which, who, whom, whose and why and to this list we usually add how as they are all used to elicit particular kinds of information.
You use what when you are asking for information about something.
You use when to ask about the time that something happened or will happen.
You use where to ask questions about place or position.
You use which when you are asking for information about one of a limited number of things.
You use who or whom when you are asking about someone’s identity.
You use whose to ask about possession.
You use why to ask for a reason.
You use how to ask about the way in which something is done.
|What||is||your name?||My name is Lynne.|
|When||is||the party?||The party is on Tuesday.|
|Where||are||you from?||I’m from England.|
|Which||is||your car?||The red car is mine.|
|Whose||is||this web site?||It’s mine.|
|Why||is||this web site here?||Because it is!|
|How||are||you?||I’m fine thanks.|
What, which and whose can be used with or without a noun as a question word.
What time is it? = What is the time?
Which car is yours? = Which is your car?
Whose web site is this? = Whose is this web site?
Whom can only be used to elicit information about the object of the sentence. Although using whom would be grammatically correct, we normally use who instead because it doesn’t sound so formal.
“Whom did you see?” would normally be expressed as “Who did you see?”
Who, what, which and whose can all be used to elicit information about the subject or object of the sentence.
If the answer is “I ate the banana.” the object question would be “What did you eat?” and the subject question would be “Who ate the banana?”
Object questions ask about the object of a sentence. The word order of the question must be changed and the question requires the use of the auxiliary verb ‘to do’.
If the answer is “I caught the train to London.” the question would be “Which train did you catch?”
If the answer is “I saw a film yesterday.” the question would be “What did you do yesterday?”
There are also subject questions. These are questions that we ask to find out about the subject. When what, which, who or whose refers to the subject, the question word comes before the verb without the use of the auxiliary verb.
If the answer is “The train to London was late.” the question would be “Which train was late?”
If the answer is “I won the race.” the question would be “Who won the race?”
