QUESTION: 221

Which of the following best completes the passage below?
Monarch butterflies, whose average life span is nine months, migrate from the Midwestern United States to selected forests outside Mexico City. It takes at least three generations of monarchs to make the journey, so the great-great-grandchildren who finally arrive in the Mexican forests have never been there before. Yet they return to the same trees their forebears left. Scientists theorize that monarchs, like homing pigeons, map their routes according to the earth’s electromagnetic fields. As a first step in testing this theory, lepidopterists plan to install a low-voltage transmitter inside one grove of “butterfly trees” in the Mexican forests. If the butterflies are either especially attracted to the grove with the transmitter or especially repelled by it, lepidopterists will have evidence that

monarch butterflies have brains, however minuscule
monarch butterflies are sensitive to electricity
low-voltage electricity can affect butterflies, whether positively or adversely
monarchs map their routes according to the earth’s electromagnetic fields
monarchs communicate in intergeneration allyvia electromagnetic fields

QUESTION: 222

In general, a professional athlete is offered a million-dollar contract only if he or she has just completed an unusually successful season. However, a study shows that an athlete signing such a contract usually suffers a decline in performance the following season. This study supports the theory that a million-dollar contract tends to weaken an athlete’s desire to excel by diminishing his or her economic incentive.

Which of the following, if true, would most strengthen the conclusion drawn above?

On the average, athletes whose contracts call for relatively small salaries with possible bonuses for outstanding achievement perform better than other athletes.
Athletes are generally offered million-dollar contracts mainly because of the increased ticket sales and other revenues they generate.
Many professional athletes have careers marked by year-to-year fluctuations in their overall levels of performance.
On the average, higher-salaried athletes tend to have longer and more successful professional careers than do lower-salaried athletes.
Six of the ten leading batters in the National League this season signed million-dollar contracts during the off-season.

Dr. A: The new influenza vaccine is useless at best and possibly dangerous. I would never use it on a patient. Dr. B: But three studies published in the Journal of Medical Associates have rated that vaccine as unusually effective.
Dr. A: The studies must have been faulty because the vaccine is worthless. In which of the following is the reasoning most similar to that of Dr. A?

Three of my patients have been harmed by that vaccine during the past three weeks, so the vaccine is unsafe.
Jerrold Jersey recommends this milk, and I don’t trust Jerrold Jersey, so I won’t buy this milk.
Wingzz tennis balls perform best because they are far more effective than any other tennis balls.
I’m buying Vim Vitamins. Doctors recommend them more often than they recommend any other vitamins, so Vim Vitamins must be good.

QUESTION: 224

Bill: Smoke-detecting fire alarms can save lives. I believe that every apartment in this city should be required by law to be equipped with a smoke detector.
Joe: I disagree with your proposal. Smoke detectors are just as important for safety in private houses as they are in apartment.

From this exchange, it can be inferred that Joe has interpreted Bill’s statement to mean that

the city should be responsible for providing smoke detectors for apartments
residences outside the city should not be equipped with smoke detectors
only apartments should be equipped with smoke detectors
the risk of fire is not as great in private houses as it is in apartments
the rate of death by fire is unusually high in the city in question
