change to active voice : a new manager had been hired before john left the company

Answer 1

Answer:

The committee had hired a new manager before John left the company

Answer 2

Answer:

'Before John left the company, the new manager had been hired.' It is the correct answer.

Explanation:

In the active voice, the 'subject' will be at the 'beginning of the sentence' and the 'object' will be 'at the end'. The tense will change accordingly.  

When it comes to 'passive voice', the 'object' will be at the 'beginning of the sentence' and the 'subject' will 'be at the end'. The 'tense of the verb' will 'change accordingly'.
