问题 Recent scientific studies have proven that ulcers are caused, at least in part, by the heliobacter bacterium. Dr. Redding has hypothesized that a natural way to prevent and cure ulcers is to eat large amounts of raw broccoli, which contains potent organic compounds that are beneficial to gastric health.    All of the following statements support Dr. Redding’s hypothesis, EXCEPT:
选项 A、It has been shown that people who consume raw broccoli on a regular basis have a 65 percent lower chance of developing ulcers than do the general population.
B、One of the organic compounds found in broccoli has been shown to have an antibiotic effect on the heliobacter bacterium.
C、Dr. Redding conducted a study in which groups of patients suffering from ulcers either ate large quantities of broccoli or ate a diet that included no vegetables; several of the patients who ate the large quantities of broccoli showed marked improvement i
D、Broccoli is one of the most potent dietary sources of antioxidants, the organic compounds shown to combat the free radicals that are thought to cause cancer.
E、Test animals with chemically induced ulcers showed some signs of improvement when raw broccoli was incorporated into their diets.
答案D
解析 The answer provides no link between broccoli and a cure for ulcers; while anticancer properties are certainly a powerful argument for eating broccoli, they are not mentioned as part of Dr. Redding’s hypothesis.
