The sentence

H. Subject-questions: ‘Who?’, ‘What?’, ‘Which?’, ‘Whose?’
Subject of object?
1. A subject-question asks for the identity of the subject.
There is no inversion and the question has the same word order as a statement:
subject verb object subject-answer
statement: Someone paid the waiter.
subject-question: Who paid the waiter? John (did).
Compare a Who(m)-question which asks for the object of a statement:
subject verb object object-answer
statement: John paid the waiter
Who(m)-question: Who(m) did John pay? The waiter.
2. Answers to subject-questions often echo the auxiliary verb used in the question:
Who can play the piano? – I can./I can’t.
When no auxiliary verb is present in the question, we use do, does or did in the answer:
Who wants a lift? – I do. Who won? – We did.
3. What, Which, Whose and How much/How many can combine with other subject-words:
What number is …? Which boy like …? Whose car is …? How many students are …?
I. Questions about alternatives, Emphatic questions with ‘ever’
Questions about alternatives (1): ‘Did you laugh, or cry?;
We can abbreviate questions after or.
Instead of: Did you laugh, or did you cry when you heard the news?
We can say: Did you laugh or cry when you heard the news?
Questions about alternatives (2): ‘Did you take it, or didn’t you?’
We can ask two questions, one affirmative and one negative, about the same thing without
repeating the verb in full.
Instead of: Did you take it, or didn’t you take it?
We can say: Did you take it, or didn’t you?
or: Did you or didn’t you take it? Did you, or didn’t you?
or: Did you task it, or not? (Not *or no*)
Emphatic questions with ‘ever’, etc.
1. We ask emphatic questions with ever to expression admiration, anger, concern, etc.
We write ever as a separate word from question-words. Compare:
Where ever did you buy that tie? Wherever you go, take your passport.
How ever did you manage it? However, I managed to persuade him.
What ever does she see in him? Whatever she sees in him, she’ll marry him.
