Original version: have you heard about the movie return of the robots? a movie studio will release this exciting new film tomorrow.
revised version: have you heard about the movie return of the robots? this exciting new film will be released tomorrow.
which best explains why a writer might revise the second sentence to use passive voice?
a. to make it clear that the movie studio is performing the action of the verb
b. to intentionally conceal the name of the film
c. to put more emphasis on the film itself, rather than on the movie studio
d. to the reader better understand how movie studios operate

C. to put more emphasis on the film itself, rather than on the movie studio

Explanation:

The passive voice is a grammatical voice used to put emphasis on the thing or person that receives or experience an action instead of the thing or person that performs the action. Therefore, when the writer chose to use the passive voice in the sentence "This exciting new film will be released tomorrow," they did so to put more emphasis on what's important: the film itself, rather than on the movie studio which it's the thing performing the action of "release."

C. to put more emphasis on the film itself, rather than on the movie studio

yes the first one is correct .

b. failure at least that one seems the most negative out of all of the answers provided pls correct me if i'm wrong. : ))
