Question

we wrote clearly on the wall that we want freedom . (change the voice)

Answer 1

In a sentence with an active voice, the subject performs the action which is denoted by the verb. In other words, the subject is the doer of the verb's action. Whereas in a passive voice, the subject is not active but by the verb is acted upon.

The above sentence "we wrote clearly on the wall that we want freedom." is in active voice and in a passive voice it would be written as:

We want freedom was clearly written by us on the wall.

Answer 2

On the wall, we clearly wrote that we want freedom.

When the sentence is changed into any kind of voice then the meaning of the sentence would not be changed.

In fact, the sentence is highly recognizable into many number of aspects that could be clearly seen into various activities but the meaning of the sentence could not be changed.
