Tom: Sandy. It seems that only half of the students passed the final exam.
Sandy: Really? The exam     have been very difficult this time.
Tom: Well, I’m really (surprise) too. There are many students who definitely didn’t fail. According to Jack, there are eight boys in his class who failed,   (include) himself and Scott.
Sandy: Oh! Scott is  of the top students in the college. What about his sister, Kate? Did she pass?
Tom: Oh, yes. It seems she     (get) good marks.
Sandy: That’s    (absolute) unbelievable. ! Scott was    much better student than his sister, and has been working so hard for the last few months.
Tom: It seems   (fair), doesn’t it? But, from    I’ve heard, perhaps he worked too hard. He was ill during the week of the exam.
Sandy: Oh, I see. These things happen, sometimes. I suppose the teacher will take his illness into account and give him a pass.
Tom: Well, there is a rumor going around  the head of the Department is leaving.
Sandy: Because of the bad result, you mean?
Tom: Well, I suppose so. I’m not sure. Maybe Mr. Smith is going to be the new Department Head.
