Basically, they’re highly reactive【C4】______of oxygen that are missing an electron.【C5】______for that missing electron, they steal them from normal cells, damaging the healthy cell and its DNA in the【C6】______This damage eventually【C7】______to any number of major health problems, including heart disease, memory loss, and cancer.
Antioxidants, however,【C8】______with this process by giving free radicals one of their own electrons to stabilize them. Or they combine with free radicals to form different, more【C9】______compounds. There are also antioxidant enzymes that help free radicals react with other chemicals to produce safe, instead of toxic, substances. Antioxidants, for instance, help prevent "bad" LDL cholesterol from becoming【C10】______and forming plaque(斑). This is the reason the health establishment is so insistent on people eating more fresh produce: It provides around-the-clock defenses against free-radical damage to your arteries.

选项
答案
B
解析
该空格前为主语This damage,空格后为to any number…,该句缺少谓语,因此填入该空格的词应为动词。根据句意和上下文语义关系可知,所选单词应表示“导致,引发”的意思,选项中只有B符合,contribute意为“起作用,促成”,而且contribute to sth.是固定搭配,表示“造成,导致”的意思。
