She _________ definitely drive to work if she had a car.
- would 2) should 3) might 4) shall
An English quiz I took recently included the above question. I thought both "would" and "should" could fit into the blank, and chose "would" anyway, but the answer was "should".
Is there anything wrong with "She would definitely drive to work if she had a car."? Or is there any reason that "should" better fits in the sentence although "would" is also okay?
