136. To cut costs, a local town stopped adding fluoride to its water supply. After the change, local dentists noticed a 25% rise in their number of patients. Clearly, removing fluoride had negative effects on dental health in the town.

The argument depends on assuming which of the following?
  1. At least some of the dentist visits were due to a decrease in fluoride intake.
  2. Most of the people in the town always drank from the water supply.
  3. Cutting the fluoride supply was an effective way to reduce costs.
  4. A 25% rise is an abnormally high change in the number of dental patients.
  5. Local dentists always keep meticulous records on their numbers of patients.

137. A recent study of 5,000 auto accident victims showed that the driver of the car had only a 50% chance of injury in accidents, but passengers in the car were injured 75% of the time. This shows that riding as a passenger is more dangerous than driving because collisions are more likely to impact other parts of the car than the driver’s seat.

Which of the following, if true, most seriously weakens the argument?
  1. Small cars are much more dangerous to ride in than large cars, and are more common.
  2. Rear end accidents are much more common than head on collisions.
  3. Most cars are equipped with airbags for both the driver and front passenger.
  4. Drivers are likely to be more distracted with passengers in the car.
  5. Drivers are much more likely to wear a seatbelt than are their passengers.

138. In a review of popular music, researchers found that the common themes of love and betrayal accounted for the subject matter in roughly 80% of songs. Despite the common themes, many people still continue to spend money on new popular music.

Each of the following, if true, would contribute to an explanation of the apparent discrepancy above EXCEPT
  1. Even if the subject is the same, there are so many emotions related to love and betrayal it is possible to sing of them in many different ways.
  2. Many people like to listen to music expressing what they themselves find hard to express, which are often feelings of emotions such as love or loss.
  3. While love songs are always popular, the biggest hits of the past few years have all been songs with a political message.
  4. Although most songs are about love or betrayal, artists find new ways to engage the material, as many are now singing about love between people of the same gender or different races.
  5. People find comfort in listening to songs about love or betrayal after suffering a break-up, even if they have heard the subject matter many times before.

139. Crocodiles have evolved to become large and powerful enough to eat even large animals, while also staying small enough to move quickly to avoid predators. Fossil evidence suggests that crocodiles were once up to 40 feet long, but began reaching smaller adult sizes as time passed. It follows that the very smallest crocodiles were most likely to live to adulthood because they could move quickly.

Which of the following describes a flaw in the reasoning of the passage?
  1. It overlooks the possibility that crocodiles evolved slowly over millions of years.
  2. It overlooks the possibility that intermediate sized crocodiles may have been most successful in living to adulthood.
  3. It overlooks the fact that size varies between male and female crocodiles.
  4. It presumes, without providing justification, that crocodiles are both predator and prey.
  5. The argument assumes that crocodiles are aware of how powerful and large they become.

140. Historian: “When the computer was first invented, most people involved never imagined that computers could become as small as they are today, and certainly never imagined that each person would own one or more computers. They were intended mainly as a tool for universities and governments and were incredibly expensive. Given the rapid progress in computer technology in recent decades, it is likely that it is hard to predict even today how computer technology will develop and what new uses we will find for computers.”

Which of the following is most strongly supported by the historians statements?
  1. Computers will develop in a way that we find impossible to predict today.
  2. When computers were first developed, they were not intended as personal devices.
  3. Computers are more appropriate for universities and governments than individual users.
  4. Looking at the history of computers makes it clear that it’s hard to predict the future development of the field.
  5. Early developers of computers were naïve in assuming that computers would not advance as much as they have.
