Transforming questions in passive voice-

• A statement in passive voice has to be in the form of object+verb+subject.
• But as this is a question asked in active voice and we are expected to change it into passive voice, the question will start with the particle 'by'.
• The subject will change to the third person('who' gets converted to 'whom'), and the tense of the verb will transform to the past tense( 'was making' changes to 'was made').
