Question

1. He asked me, "Why is she crying?"into passive sentences ​

Answer 1

She is crying. The verb cry is both transitive and intrsitive. As "cry" is intransitive or there's no object in the sentence presented, you cannot change the sentence into the passive voice. Look at the following example in which the cry has been used as a transitive verb: The mother cried tears of joy when she found her child.
