The elaboration of the oo7 conversation style was carried out thanks to the help of it, which caused a revolution in our lives.
Explanation:
A sentence that has a passive voice is one where the subject undergoes the action presented by the verb and does not perform the action presented by the verb. As you may already know, the verb is the word that promotes an action or a state, while the subject is the term that allows the action of the verb to happen, promoting it in some way. In this case, in the sentence shown in the question above, we can see that the verb is the word "help" and the subject is the word "it" in the first sentence. "It" is promoting the action represented by the verb "help," which makes this sentence a active voice sentence. To transform it into the passive voice, we must rewrite this sentence, making "it" start to suffer the action of this verb. This can be done as follows:
