虚拟语气与情态动词 — 英语阅读题

Read the passage and answer the question. Last month, a campus volunteer club planned a weekend service trip to a nursing home. The organizer, Kevin, wrote in the group notice: "If we had booked the bus a week earlier, we would have got a group discount." Later, the club advisor reviewed the plan and said, "I suggest that every volunteer bring a first-aid kit, and I insist that the trip leader carry a backup list of all participants' phone numbers." At the meeting, one member complained, "I wish I knew how to communicate with elderly people better; if I had attended last term's training session, I would feel more confident now." The advisor added that the weather report suggested that the weekend would be sunny, so outdoor activities would remain as planned. Question: Which statement best reflects the use of the subjunctive mood in the passage?
