Answer:
d. by acknowledging that some people disagree with his position
Explanation:
Roberto addresses this new information "by acknowledging that some people disagree with his position"
Roberto cannot ignore the new source or call it foolish but can only acknowledge it and then finds better reasons to support his own claims above what the new information says.
Answer:
Either the narrator is having a bad day, or is just clumsy. Just by this short part of the story, we can infer that he/she is a kind person. They use the word, "sorry," and were embarrassed yet polite when they realized that they didn't have enough money. When the generous person behind them gives them money, the narrator is thankful. However, the "generous" person isn't so generous. They just want to leave.
hope this helps
