The correct answer would be the first option. A collective subject is a noun (functioning as the subject) that describes a group made of many parts. For example, the words "team" which means a group of people playing. Another one is "pack" used in a pack of wolves, which means a group of wolves.
It would be it is a primary subject in the story that helps understand the hidden motives of the main character.
The answer is actually B. I'm taking the test and got the answer.
Torah is the five books of Moses. Torah is law that god revealed to those 5 Moses and it is actually recorded on those first 5 books.
