change into passive

Is the work finished by him in one month? -This is the answer.

About passive voice:

• The given sentence is in active voice in interrogative form. We have to change it into passive voice.
• When a sentence is changed into passive voice, the subject becomes passive/ inactive. So the subject 'he' changes into 'by him'.
• The object and the action done take importance. So the object 'the work' is important in passive form. But as it is a question, the verb should precede the object (the work).
• The verb that should begin the sentence is 'is', because the tense used here is simple present perfect tense (does)
• The tense must be retained. The verb takes its past participle form. Thus the verb 'finish' changes into 'finished'.
• The 'be' verb will precede the past participle according to its tense. So the sentence will begin with 'is'.
• Therefore the answer is: Is the work finished by him in one month?
