質問 1：
In a population cycle, predators eat and reduce the number of prey. If the number of predators is reduced, the number of prey will gradually increase. Eventually, the predator population will increase, and the population cycle will continue.
Which pair best demonstrates a predator-prey relationship?
A. sheep and cattle
B. robins and pigeons
C. snakes and mice
D. honeybees and ants
E. frogs and toads
正解：C
質問 2：
Daily weather patterns are often the result of temperature differences, patterns of air flow, relative humidity, condensation, or evaporation. A warm front forms when a warmer air mass pushes a cold air mass ahead of it. Precipitation over a large area can occur along a warm front.
Based on this information and diagram, what would most likely happen if a mass of hot, humid air encountered a colder air mass in the northern portion of Earth's surface?
A. rain or snow
B. tropical breezes
C. earthquakes
D. surface fires
E. hurricanes
正解：A
質問 3：
A food chain is a way of showing food relationships among a group of organisms that share an environment. The illustration at the left represents a freshwater food chain.
What is most likely to happen if the supply of large fish in a pond is reduced by extensive fishing?
A. The amount of algae will increase.
B. Humans will eat more algae.
C. Small fish will get smaller.
D. Large fish begin to eat algae.
E. The population of small fish will increase.
正解：E
質問 4：
The left side of the brain dominates in verbal skills, reading, writing, and logical thinking. The right side of the brain is adept at space and pattern perception. While the right side does not express speech, the right side dominates in visual imagery and spatial relationships.

A. using depth perception to park a car
B. having a conversation on the telephone
C. looking at a picture in a museum
D. recognizing a person's face
E. recognizing a song on the radio

An airplane that is flying through the air is affected by basically four forces acting on it. They are indicated on the diagram below.
-- Exhibit -
When the airplane is flying at a constant speed, all of the forces acting on the plane are in balance.
If all four forces shown in the diagram are in balance, which statement best describes the situation? (The wind speed or turbulence has no effect on the plane's position or motion.)
A. The plane is slowing down.
B. The plane will crash because nothing is holding it up.
C. A major change in one force would not affect the plane's motion or position.
D. The plane is weightless.
E. The plane is in a state of equilibrium.
正解：E
質問 6：
The widespread use of antibiotics has created a frightening threat to our safety. While antibiotics have offered life-saving treatment for countless diseases, their misuse and overuse have contributed to the evolution of deadly bacteria that are resistant to treatment. Although there is a reluctance to give up the demand for antibiotics, most people accept scientists' warnings of impending catastrophe.
Which choice best explains why doctors now prescribe antibiotics less often than in the past?
A. Antibiotic use causes frequent digestive upsets.
B. Insurance does not cover many antibiotic prescriptions.
C. The newer antibiotics are too expensive for the average consumer.
D. Time constraints prevent doctors from writing as many prescriptions.
E. Bacteria become resistant to treatment by certain antibiotics.

The pH scale is a measure of the acidity of a substance. The numerical range of the scale is from 0.0 to 14.0. A midpoint pH of 7.0 designates a neutral substance (neither acid nor base). A pH lower than 7.0 denotes an acid substance, whereas a pH higher than 7.0 denotes a basic substance.
-- Exhibit -
Which of the following substances is the MOST basic?
A. human blood (pH = 7.4)
B. tomato juice (pH = 4.2)
C. pure water (pH = 7.0)
D. sodium carbonate (pH = 12.5)
E. black coffee (pH = 5.0)
