### HideShow timer Statistics

Since 1975 there has been in the United States a dra-

matic decline in the incidence of traditional childhood

diseases such as measles. This decline has been accom-

panied by an increased incidence of Peterson's disease,

a hitherto rare viral infection, among children. Few

adults, however, have been affected by the disease.

Which of the following, if true, would best help to

explain the increased incidence of Peterson's disease

among children?

(A) Hereditary factors determine in part the degree

to which a person is susceptible to the virus

that causes Peterson's disease.

(B) The decrease in traditional childhood diseases

and the accompanying increase in Peterson's

disease have not been found in any other

country.

(C) Children who contract measles develop an

immunity to the virus that causes Peterson's

disease.

(D) Persons who did not contract measles in child-

hood might contract measles in adulthood, in

which case the consequences of the disease

would generally be more severe.

(E) Those who have contracted Peterson's disease

are at increased risk of contracting chicken pox.

I got the correct ans (c) by process of elimination.but could someone shed some light on the explanation?

C is correct.

Author is saying that cases of Measles have decreased, at the same time cases of Peterson's disease has increased, which until now was a rare disease. Logically this means there is a direct relationship between "decrease of Measles" and "increase of Peterson".

Option C provides this relationship, by saying, children who contract measles develop an
immunity against Peterson's disease.

I would agree with bigoyal's explanation.
