Bruno and shmuel are the protagonists because they are mostly mentioned in the story
I think the correct answer is the first one: "The government controls every aspect of life in the community so that citizens are not at all aware of life outside their own society." Since the establishment of Sameness, things that made living difficult had disappeared, such as snow and hills, and now people hardly remember it.
Based on the given scenario above, the answer would be option B. A secondary source. It is a secondary source since it is already seen in the magazines or printed articles and not directly from the person him/herself. Hope this answers your question.
C. A clause is a group of related words, but a phrase is Not.
