Question 1
Air travel is becoming increasingly more dangerous. In the last year there have been seven major collisions resulting in over 700 deaths, more deaths than in any previous year.
Which statement, if true, would most weaken the argument above?
A. Since the volume of air traffic has been increasing all the time, an increase in the number of deaths due to collisions does not necessarily mean greater danger.
B. The increase in collisions can be explained by hijackings, and unusual weather.
C. Mortality per passenger mile is lower than for air travel than for any kind of surface transportation.
D. The increase in deaths due to collision in air travel has proceeded at a rate identical to that for deaths in all other major forms of transportation.
E. Last year the average number of passengers per flown plane was significantly lower than that of previous years.
Question 2
A public health official reported that 60 percent if the children at summer school have never had the measles or chicken pox, and that of this 60 percent not one child has ever been observed to eat the cheese served in the school lunches. From this he concluded that children who abstain from cheese products protect themselves from most childhood disease.
Each of the following, if true, would strengthen the official’s argument EXCEPT:
A. Medically speaking, whatever serves to inhibit measles and chicken pox will generally inhibit the entire spectrum of childhood diseases.
B. The observations the official carried out were extremely accurate, and all those observed to abstain from cheese at school did, in fact, abstain.
C. The children’s eating habits are the same at school as anywhere else, and those who abstain from cheese products at school do so in general.
D. Recent research has pointed to a deficiency in cheese products as one of the major causes of measles and chicken pox infections.
E. Most cheeses and cheese products harbour bacteria that are known to be causative agents for many childhood diseases, such as measles and chicken pox.
Question 3
U.S. officials complain that the country’s trade deficit with Japan is due to the fact that Japan’s markets are not open enough to imports and investment. Japanese officials reply that the United States should concentrate on improving its school systems and investing more money in scientific research and worker training.
It can be inferred from the statements above that the Japanese officials most probably hold which of the following opinions?
A. The United States should open its own markets to more imports and investment.
B. The trade deficit between the United States and Japan is more the result of poor American industrial performance than Japan’s import restrictions.
C. The trade deficit between the United States and Japan is a result of Japan’s closed markets.
D. U.S. schools systems foster a mistrust of Japan that prevents U.S. businesspeople from negotiating intelligently.
E. Better education and worker training can help shrink the trade imbalance, but should not be counted on to close the gap entirely.
Question 4
Doubling the cost of public transportation to compensate for money lost by declining ridership would be disastrous. The greater expense would only further discourage commuters who are already dissatisfied with the poor condition of buses and trains. If the fares are increased, many commuters will choose to drive their cars instead, causing pollution and traffic congestion. As a result, the city will lose money and become even more noisy and smog-filled than it is now.
Which of the following is an assumption made in advancing the argument above?
A. Commuters who decide to drive instead of using public transportation will not share rides with one another.
B. Commuters will not park their cars in garages and thereby spend more money than they would by using buses or trains.
C. The condition of public transportation will not improve as a result of the fare increase.
D. Commuters who use their own cars currently outnumber those who use buses and trains.
E. A significant number of people who now use public transportation have cars or can easily obtain them.
Question 5
The cause of the peculiar columnar growth pattern displayed by junipers growing near burning underground veins of lignite coal has never been convincingly explained. Until recently, the accepted theory posited that the abundance of carbon monoxide in the local atmosphere caused the columnar growth. However, a new theory holds that the cause is the persistent heat present near these underground fires that, while not intense enough to inflame the trees, can nonetheless change their normal growth pattern.
The existence of which of the following would provide the strongest support for the new theory?
A. A columnar juniper growing in an atmosphere of intense heat and an absence of carbon monoxide.
B. A normal juniper growing in an atmosphere of intense heat and an absence of carbon monoxide.
C. A columnar juniper growing in an atmosphere of normal heat and a high concentration of carbon monoxide.
D. A normal juniper growing in an atmosphere of intense heat and a high concentration of carbon monoxide.
E. A columnar juniper growing in an atmosphere of intense heat and a high concentration of carbon monoxide.
