Please help in S-V makes sense together

There are a few things wrong with this sentence.

To be grammatical, it would need to read:

"The novel had been written in the baroque period."

This sentence is now in the passive voice, meaning that the subject isn't doing the action. Instead, the action is being done to the subject. You can tell it's in the passive voice because the verb is "had been written" instead of "had written". This sentence is correct.

However, "The novel had written in the baroque period" is wrong for multiple reasons. First, "had written" does imply that the novel wrote something. That doesn't make logical sense. But, also, when you use the word "written", you generally need to clarify what somebody wrote. For example, "I wrote a book" or "He wrote the magazine article." It's possible to use "wrote" in a more general sense, just saying that somebody is or was a writer, but you'd usually need to have an "object" for the verb in order for the sentence to be correct. This sentence doesn't have one, which is another reason that it's wrong.


This sentence is correct and is in the active voice.


This sentence is also correct. In this sentence, 'deflate' just means 'decrease.' It's possible for eagerness to decrease; it doesn't matter if it did it 'by itself'. This sentence is also in the active voice, just like the previous one.


These are both correct for the same reasons as above.
