In the United States, people who contract pneumonia are ill for six

OFFICIAL EXPLANATION

This is a weaken the argument question.

Identify the argument. We can find the argument in the last line of this example. If a newlywed couple from New York were to have a family in Nevada, their children would be ill from pneumonia for less time than if they lived in New York.

Anticipate the answer, if possible. We will need to find an answer that will show New Yorkers who move to Nevada will not necessarily be ill from pneumonia for less time than if they had remained in New York.

Eliminate the answer choices that do not weaken the argument. Which of these choices will show that New Yorkers who move to Nevada will not necessarily be ill from pneumonia for less time than if they had remained in New York? B, C and E have nothing to do with pneumonia in Nevada. Choice A simply states what insurance companies believe, but does not disprove the argument. Only choice D weakens the argument by stating that genetically-determined factors found in Nevadans, but not New Yorkers, result in the shorter duration of pneumonia.
