Question

Who can cross the river?
change to passive voice​

Answer 1

By whom can the road be crossed? is a passive voice.

Active and Passive voice in English grammar:

• Active voice is a voice that refers to the condition in which the subject is performing its action.
• In passive voice, the subject receives the action and is replaced by the object and vice versa.
• However, to make a passive voice third form of the verb is used.

Answer 2

By whom can the river be crossed?

Here, we have changed the voice of a sentence from active voice to passive voice. However, while making these changes, a few points are to be kept in mind. They are as follows-

• There is an addition of the word 'by'. Usually, it is done at the end. However in interrogative sentences like this, 'by' is added towards the beginning.
• The question mark (?) should not be missed out.
• In this case, the subject has been mentioned towards the beginning.
• The intended meaning of the sentence should not be changed in any way.
