Complete the sentence with the correct form of the verb in brackets: I currently work weekends, but I have made a firm decision about free Saturdays: if I had Saturdays free, I ___ at the animal shelter. (volunteer)
Bonne réponse
would volunteer
Explication
Would volunteer presents the speaker's firm intended result under the unreal condition of having Saturdays free. Could volunteer would express mere possibility and would not match the stated decision.
