A、She was being troubled with her heart. B、She was being troubled with her skin. C、She was being troubled with serious headache.

Mrs. Black was having a lot of trouble with her skin, so she went to her doctor about it. He could not find any thing wrong with her and at last gave her a list of the things that he thought she should not eat, as any of them might be the cause of her skin trouble. Mrs. Black carefully put the list beside the telephone while she went out to a ladies’ meeting. When she got back home two hours later, she found her husband was waiting for her. He had a big basket full of packages beside him, and when he saw her, he said, "Hello, dear, I have done all your shopping for you."
    "Done all my shopping?" she asked in surprise, "But how did you know what I wanted? ""Well, when I got home, I found your shopping list beside the telephone", answered her husband, "So I went to the shops and bought everything you had written down."
    Of course, Mrs. Black had to tell him that he had bought all the things the doctor didn’t allow her to eat.
