问题    When a rare disease ALD threatened to kill the four-year-old boy Lorenzo, his parents refused to give up hope. Doctors explained that there was no cure for ALD, and that he would probably die within three years. But Lorenzo’s parents set out to prove the doctor’s wrong.
   The parents devoted themselves to keeping their son alive and searching for a cure. But doctors and the families of other ALD patients often refused to take them seriously. They thought the efforts to find a cure were a waste of time, and drug companies weren’t interested in supporting research into such a rare disease.
   However, the parents still refused to give up and spent every available hour in medical libraries and talking to anyone who would help. Through trial and error (反复试验), they finally created a cure from ingredients (调料) commonly found in the kitchen. The cure, named "Lorenzo’s Oil", saved the boy’s life. Despite the good results, scientists and doctors remained unconvinced. They said there was no real evidence that the oil worked and that the treatment was just a theory. As a result, some families with ALD children were reluctant to try it.
   Finally, the boy’s father organized an international study to test the oil. After ten years of trials, the answer is: the oil keeps ALD children healthy.
Scientists and doctors believed that Lorenzo’s Oil______.
选项 A、was really effective
B、was a success story
C、only worked in theory
D、would save the boy’s life
答案C
解析 由第三段倒数第二句可知，科学家和医生认为没有确切的证据证明Lorenzo’s Oil对这种疾病有疗效，这仅是理论上的治疗方法。由此可推知答案为C)。
