Answer:
First question answer is "A. In the passage, Aiden was nervous about attending his new school because it was twice the size of his elementary school, and the classes were much harder. "
Explanation: Because the others do not make any sense because B shows that was excited because his friend was their and he never showed any excitement, C shows he is depressed because he will be separated from his friends, which he was not and is not stated, D shows that he was anxious because he wanted to try out for the swim team which was never stated anywhere.
Answer: For the second question answer is "B. "You are capable of so much more than you think; you do not give yourself enough credit just like I didn't when I was younger."

Hope this helps.
