At the turn of the 20th century, Dutch physician Christiaan
Eijkman showed that disease can be caused not only by
microorganisms but by a dietary efficiency of certain substances【M1】______
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.
By the middle of the 20th century scientists believed they
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。
