But if I were to use one of these ones, would it matter which one I use?
So what's the difference between these two?
1. What do they do if there were an emergency? (Imaginary? )
2. What do they do if there is an emergency? (Future?)
For my question at the top, Is 'use' correct? Or is it supposed to be 'used' ?
3. Would it matter which one I use?
4. Would it matter which one I used? (I think it sounds odd with 'used', how come not all conditonals can use all past tense?)
Thanks.
