At the turn of the 20th century, Dutch physician Christiaan
Eijkman showed that disease can be caused not only by

now called vitamins. In 1909 German bacteriologist Paul Ehrlich

deadliest viral diseases. Smallpox, once a worldwide killer, was
completely eradicated by the late 1970s, and in the United States a【M5】______
number of polio cases dropped from 38,000 in the 1950s to less
than 10 a year by the 21st century.

were well on the way to treating, preventing, or eradicating many

答案
the一去掉the
解析
语法错误。此处考查的是冠词的用法。the是定冠词,表示特指,而此处表示“传染性疾病”,并没有特指哪种或哪几种传染性疾病,且diseases是复数,前面也不能用表示单数的不定冠词an,所以此处要将the删掉。
