I have a question about how to make a certain type of question.
There is the statement here:
The airplane has twice as many engines as it requires.
I want to make a question the answer to which is:
twice as many engines as it requires
which specifically emphasizes twice as many. Not a yes/no question, but a wh/h question.
I asked some native speakers of English and they provided me with sentences like:
How many engines does the airplane have?
How many more engines does the airplane have?
But I think the answers to those questions, for example for a plane with 8 engines, are "eight engines", and "four more engines", not "twice as many engines as it requires".
I made the following question but I wonder if it's grammatically correct:
How many times as many engines as required does the airplane have?
Does anyone have a better suggestion?
