Surveys in Lynzia indicate that while more than half of all Lynzians over thirty read a newspaper regularly, only 10 percent of Lynzians in their twenties do. Since the mean age of Lynzia’s population is quite low, with people in their twenties constituting a large proportion of the population, it is safe to predict that the percentage of Lynzians who regularly read a newspaper will be much lower ten years from now than it is today.Conclusion:
it is safe to predict that the percentage of Lynzians who regularly read a newspaper will be much lower ten years from now than it is today We see that the reasoning of the argument is basically that, since younger people don't read a newspaper, when they become the over-thirty people, newspaper readership will be lower than it is now.
Which of the following, if true, casts most doubt on the prediction?The correct answer to this Weaken question will show that, even though the evidence is true, the conclusion may not be.
A. The number of Lynzians in their twenties is less than the number of Lynzians over thirty.This information on absolute numbers doesn't indicate anything about the percentage of people who will read newspapers.
Eliminate.
B. The surveys counted someone as reading a newspaper regularly if that person read a newspaper more than four times a month.This is just a detail on how the survey worked. It doesn't indicate anything about the percentage of people who will fit this criterion in the future.
Eliminate.
C. The proportion of Lynzians who regularly read a newspaper was higher 20 years ago than it is today.If anything, this strengthens the case for the conclusion by indicating that there may be an ongoing decline in newspaper readership.
Eliminate.
D. The proportion of Lynzians in their twenties who regularly read a newspaper has always been low.This choice is interesting.
If this is true, then what's going on is nothing new. People in their twenties don't read newspapers as much as older people, but when the people in their twenties get older, they start reading newspapers.
Thus, the evidence presented may not support the conclusion that there will be a decline in readership.
Keep.
E. The number of newspapers published in Lynzia has been gradually diminishing over the last several decades.If anything, this information supports the conclusion that the number of people reading newspapers will decrease.
Eliminate.
Correct answer: D
