Answer 2

The trees have been cut.

The trees have been cut.The trees have been cut by them.

In the provided question, we have been asked to change the voice of the sentence from active to passive.

While doing so certain points should be considered. They are as follows -

• The easiest way to recognize or distinguish a sentence in active voice from one in passive voice is the usage of the word 'by'.
• The subject is generally placed at the end, right after 'by'.
• There is also an alteration in the tense of the verb. For example- Here, 'cut' has been changed to 'have been cut'. Therefore, the verb that was in the simple past tense, is now in the past perfect tense.
