PrepTest 86, Section 2, Question 15
Commentator: The reported epidemic of childhood obesity in our country is a myth. Over the last 8 years, there was only a 1 pound (0.45 kilogram) increase in children's average weight. This is not a substantial increase, so the proportion of children who are obese cannot have increased substantially.

Which one of the following contains flawed reasoning most similar to the flawed reasoning contained in the argument above?
The average summer temperature over the past five years must have increased, since most people believe that summers are getting hotter.
The proportion of employees who earn very high salaries must not have increased more than slightly over the last year, since the average salary has increased only slightly over that time.
The proportion of apartment buildings in the downtown area must have increased substantially in recent years, since a substantial number of office buildings have been converted to apartment buildings during that time.
The average weight of adults must have increased in the last few years, since restaurants have increased the proportion of high-calorie dishes on their menus in recent years.
The average price of a house must be increasing, since the proportion of household income spent on housing has increased over the last eight years.
