Task: Question Answering
Input (English): I knew he was sick because he told me so. It didn't help that he was coughing and sneezing. He hadn't been able to get out of bed for days. It looked like he had a fever. He had gone to the doctor a few days ago. He had a prescription from them, but he wasn't able to take the medicine himself. He needed it. I went to the cupboard we kept it in and took out the medicine. It was in a small bottle. The medicine was liquid, so it was easy to administer. I opened the bottle. Then I measured out a single dose into its cap. I set the cap of medicine down on the counter before grabbing a small glass of water. With both the medicine and the water in my hand, I went back to his room. He opened his mouth for me. I pressed the cap to his mouth, making sure he drank all of it. Then he had some water. 
Question: Who told them to take the medicine?
Output (English): the doctor
