    how is “The man who is sitting in the chair is my father.” different from “The man who is walking is my friend.” that in first case we should use present perfect and in second present continuous?

    if it is two women who are sitting there are my teacher? still put the “i” after “women”?
    why the verb is it “ast”, not “hast”? the subject is people
    thank you.
