Would you please answer to this question:
Which choice best fills the blank?
A: Could you water the trees in the garden?
B: If it ....... so cold, I ....... water them.
1) is not/will 2) is not/would 3) wasn't/will 4) weren't/would
Would you give a reason for the right choice.
4- because it's cold and I am not going to water them- straight second conditional.
