Which of the following, if true, would most strengthen the author’s assertion about the cause of the Lyme disease outbreak in the United States?
(A) The deer population was smaller in the late nineteenth century than in the mid-twentieth century.
(B) Interest in outdoor recreation began to grow in the late nineteenth century.
(C) In recent years the suburbs have stopped growing.
(D) Outdoor recreation enthusiasts routinely take measures to protect themselves against Lyme disease.（A）
(E) Scientists have not yet developed a vaccine that can prevent Lyme disease.
正确答案是A, 但我觉得A和B都是对的.
原文说the rise in the prevalence of Lyme disease 有两个原因,一个是an increase in the deer population, 另一个是increased outdoor recreational activities in the deer’s habitat.
B说人们对户外运动的爱好从19世纪末开始grow , 和A 起到的作用难道不是一样的吗?
有那位牛牛可以让我明白它们的区别吗? 谢谢了
