Ok, see these examples:
How many days on earth equal a day in heaven?
How many calories equal a pound of weight loss?
We have no problem so far, right?
Now suppose I want to emphasize a day in heaven and a pound of weight loss, so I put them into the beginning like this:
A day in heaven equals how many days on earth?
A pound of weight loss equals how many calories?
Do those two questions still sound right when we put How many in the middle of the sentence?
If not, then how can we emphasize a day in heaven and a pound of weight loss"in question sentences?
