-------------------------------
Which one is the passive sentence of each active sentence?
Can we use both passive forms? Does each passive voice sentence is different or the same?

Answer 1

First set ...

Since the verb in the active sentence is in the present perfect tense, the verb in the passive sentence should be, too.

~~ He has written this novel in easy English. (active)
~~ This novel has been written by him in easy English.
(Since "He" is the subject in the active sentence, some form of that pronoun needs to be in the passive sentence, too.)

Now ... how will you correct the other two sets of sentences?
