Object Questions
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'.
For example:-
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?"
Subject Questions
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.
For example:-
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?"
