input question: W: Hi, Dr. Frank. I am not feeling very well. That is why I made an appointment with you. M: I am sorry to hear that. What seems to be the trouble? W: My head has been hurting a lot lately. I never used to feel like this. M: When does it hurt the most? W: Usually, I feel fine. It only hurts when I am in class. My head starts hurting when I try to copy notes from the board. I tried sitting near the back of the room, but it doesn't help. In fact, it gets worse! M: Well, it sounds like you might need glasses. You should get your eyes checked. It should not take too long. W: Thank you, doctor. I appreciate your help. What was said before this conversation????

input question: Alex: By saving water. Interviewer: Well, how can we do that? Alex: By not using too much water when we wash dishes, take a bath, and when we do other things, like watering the plants outside. Interviewer: Oh, I think I can do that. What else? Alex: When drinking or eating something outside, you should keep the garbage until you find a trashcan to put it in because littering makes our planet dirty. Do you like seeing trash all over the ground? Interviewer: No, I don't. Do you have any final suggestions? Alex: Yes. We shouldn't waste paper because trees are being cut down to make the paper. By recycling paper, we save the forests where animals live. Interviewer: So, how can children recycle paper, I mean, everyday? Alex: Well, for example, when I was in kindergarten, I used to save the newspapers so that I could make things make out of them, like paper trees, instead of just throwing them away. Now, the children in our neighborhood collect newspapers once a month to take them to a recycling center. Interviewer: That's great. Well thanks Alex for your ideas.
