Question

He knew nothing of the modern rigour change the voice

Answer 1

Here is the correct answer:

Nothing of the modern rigour was known to him.

Explanation

The verb in the sentence was Simple Past in the active form (knew). When we convert the active voice of Simple Past into passive voice, we use passive form equivalent to the active form. The active form in Simple past is 'V2' or Simple Past form of the verb. The object is made the subject and vice versa; 'by' is added. The passive form in Simple Past is was/were +V3.  

The verb ‘know’ takes the preposition ‘to’.

Answer 2

Nothing of the modern rigour was known (to him)

Explanation:

• Active voice implies that the sentence has a subject which acts upon the verb. Passive voice implies that the subject is the recipient of the verb’s action
• The passive voice is used when the action is the focus, not the subject. It is not important/ not known who does the action for example, Somebody has eaten the last piece of cake (active). The last piece of cake has been eaten (by somebody) (passive).  As a rule, the doer is only mentioned in the passive sentence if it is essential/important new information that cannot be omitted, for example JRR Tolikien wrote the Lord of the Rings (active). The Lord of the Rings was written by JRR Tolkien (passive).
