CR 1 In 2006, there were 4,736 fatalities caused by road accidents in California. That year, there were 4,810 deaths caused by motorcycle accidents nationwide. Officials in the Department of Transportation hypothesized that in 2006, it was not much safer to be a driver or a pedestrian in California than it was to be a motorcyclist anywhere in the USA.
Which of the following investigations is most likely to expose a logical flaw in the above hypothesis?
(A) Comparing the number of fatalities separately for drivers and for pedestrians
(B) Comparing the number of casualties in each group per 1,000 people, instead of the total number of casualties
(C) Comparing the number of fatalities in Californian motorcycle accidents to the number of fatalities in motorcycle accidents nationwide
(D) Calculating the ratio between the fatality totals in both groups
(E) Comparing the 2006 statistics with statistics of previous years

CR 2 The average giraffe is six and a half to seven foot tall at the age of six months. Therefore, if a six-month-old giraffe is over seven feet tall, it grew by more inches each month than the average giraffe does.
Which of the following indicates a flaw in the reasoning above?
(A) The giraffe's weight is not taken into consideration.
(B) Overall faster growth and faster growth per month are not the same.
(C) Some six-month-old giraffes are almost eight feet tall.
(D) Height is only one measure of normal development in giraffes.
(E) The average height at six months for giraffes in general is not the same as the average growth rate of a single giraffe.
