Answer 2

The given sentence cannot be able to change into passive voice.

Explanation:  

• In English there are two types of voice- the active voice and passive voice. Changing of voice is possible only when there is a supporting verb.  

• The voice is changed by making the correct participle tense of the supporting.

• However if the supporting verb is absent there cannot be any different subject and object, as is the case in this statement.  

• Here only the subject exists which is 'They' but no object. Hence change of voice is not possible.
