Answer:
"Last year, he was the freshman class vice president"
Explanation: This statement proves that he is capable of being a leader.
"Longing" is another word for: (C) NOSTALGIA
When you are nostalgic about something, you long for something or someone in the past. For example, a person who migrates to another country might become nostalgic for the foods and culture of his own country as he tries to settle in.
The subject of a talk, a piece of writing, a person's thoughts, or an exhibition
In this context, "redundancy" refers to a sentence in the paragraph that isn't useful or not needed.
With that being said, I would chose answer choice C. There is no extra detail given about the "past history."
