F: Morning, Mr. Johnson. Do you need some more medication? ,M: No, my leg is feeling fine actually. But this bed is really uncomfortable. ,F: You told me that you'd like to be able to move and control it yourself. ,M: That's true. But I don't know how to use it. This controller is huge and there are too many buttons. ,F: Yeah, it can be pretty confusing. See these buttons at the top here. They control the part of the bed near your back. So you can either sit up or lie down.
(A) M: Really? You mean you don't think it's can be pretty confusing? And you mean I should press the buttons in the middle to sit up straight? (B) M: So, there buttons at the bottom here control the part of the bed near my back? But I should press the buttons at the top to sit up straight? (C) M: Yeah, this is small but there are too many buttons. And you mean I should press the buttons at the bottom to sit up straight, right? (D) M: I’m sorry, I don’t understand. Could you say it again?
