Answer:
The correct answer is concerned.
Step-by-step explanation:
Once Upon a Time is a short story written by South African writer Nadine Gordimer and it talks about a frame story about a married couple that lives in a suburb that keeps color people out; the couple is afraid of the riots in the city nearby the suburb.
Before the excerpt, the woman told the man that she was very afraid of the things that were happening; to calm her down, the husband fitted the electronically controlled gates. He is very concerned about his wife, so it is the correct answer.
