A) because he is the murderer
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.

I think the reason why the summary need to be revised is : C. the summary lacks transitions that connect ideas
For example, we need to add transition between -enkai wanted to save his cattle- and -He grew a tree that bridged the sky and the earth-
