In the text book that I am supposed to use in my lessons I have this explanation on the difference between subject and object questions:
I want you to especially pay attention to this sentence above:
"In subject questions ... we don't normally use an auxiliary verb in the Present or Past simple"
Then, right on the next page I have this exercise:
I this task, as far as I understand, students are asked to come up with two questions for each sentence and one question must be an object question and the other one must be a subject one.
However, when I look at the sentence 3 there:
it looks to me like both suggested questions are object questions:
"What did Eva do yesterday?"
"How many films did Eva watch?"
At least, in both of these questions the auxiliary verb "did" is used, which, according to what is written above ("In subject questions ... we don't normally use an auxiliary verb"), means that none of them is a subject question.
Can anyone, please, explain to me my confusion?
