124. 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.

The passage says:

Lyme disease, which is caused by bacteria that are transmitted by deer ticks. It occurred only sporadically during the late nineteenth century but has recently become prevalent in parts of the United States, largely due to an increase in the deer population that occurred simultaneously with the growth of the suburbs and increased outdoor recreational activities in the deer’s habitat.

og says:

The best answer is A. The author asserts that the recent high incidence of Lyme disease can be attributed to an increase in the deer population. The author’s assertion would be supported if it were to be shown that the deer population was lower in the late nineteenth century, when the incidence of Lyme disease was sporadic. Choice B is incorrect because it does not provide information clearly supporting the author’s assertion that Lyme disease increased as a result of an increase of the deer population and an increase in outdoor recreational activities in the deer’s habitat.

I am so confused. Low deer population is paradoxical with the increased deer population. In addtion, B offers a way that the proliferation of human activity in the deer’s habitat, suggesting that contact between humans and deer ticks has increased significantly since the late nineteenth century. Why og chose A rather than B?

OH,I got it. A means increase. B mention nothing about 20th century.
