7. Why did Mumbet run away from the Ashleys? A. She found an employer B. She wanted to be a lawyer C. She was hit and got angry D. She had to take care of her sister

7. C 解析：推理题。根据第二段前 3 行 One day, Ashley’ s wife tried to strike Mumbet’s sister with a spade. Mumbet protected her sister and took the blow instead. Furious, she left the house and refused to come back.可知 Ashley 的妻子要打她的妹妹，Mumbet 为了保护妹妹而被 Ashley 的妻子打了，之后她就离开了 Ashley 的家。由句意知她离开是因为她被打了，她非 常生气，所以才离开。故 C 正确。
