The amount of carbon dioxide in the atmosphere is increasing, therefore contributing to the phenomenon called the greenhouse effect. The end result is an increase in average temperatures worldwide.
A decrease in global warming could result if we reduced the consumption of materials that give off carbon dioxide when burned.

To reduce global warming, what should be used LESS?
A. electricity
B. fossil fuels
C. nuclear energy
D. solar energy
E. geothermal energy
正解:B
質問 2:
Burning paper requires the chemical combination of oxygen in the air with the material composing the paper. Which would cause the paper to burn faster?
A. using a thicker piece of paper
B. increasing the oxygen around the paper
C. putting the burning paper in a closed container
D. wetting the paper before burning
E. using only pastel shades of paper
正解:B
質問 3:
For an organism to survive, it needs food, water, oxygen, living space, and the ability to maintain a relatively constant body temperature. Warm-blooded animals have ways to adjust their body temperature to compensate for fluctuations in environmental temperature. The body temperatures of cold-blooded animals, such as fish, vary directly with the temperature of their environments.
Power plants and factories can release heated water into nearby rivers and steam into the air.
Which animals downstream of a power plant would be the most affected by thermal pollution discharges from the power plant?
A. people fishing in the river
B. birds sitting on the riverbank
C. moose standing in the shallow river water
D. fish swimming in the river
E. elk grazing near the river
正解:D
質問 4:
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.
正解:E
質問 5:
A scientist published his work in a scientific journal, and it generated much excitement in the scientific community. However, when other scientists across the world did the same experiment to try and repeat the results, it proved to be impossible.
When this type of event occurs, which statement describes the most important factor about a scientific finding's acceptance by the scientific community?
A. reproducible by other scientists
B. of considerable practical value
C. presented by a team of scientists
D. based on an important concept
E. published in a scientific journal
正解:A
質問 6:
Science is a systemized body of knowledge based on observation and experimentation. Technology involves applied science and the practical applications of scientific knowledge. The making of lenses for eyeglasses is a technology that is based on the scientific principles of optics explaining how light rays are bent by finely ground lenses.
Which example would be considered science rather than technology?
A. can opener
B. microscope
C. seesaw
D. structure of the atom
E. fishing rod
正解:D
質問 7:
Advances in rocketry are tied closely to the application of Newton's Laws of Motion. These laws help us understand how things move. Movement occurs when forces are unbalanced; if opposing forces counterbalance each other, then no movement occurs.
In the diagram below, the amount of thrust (force) produced by air is determined by the air escaping from the balloon.

Based on the information and diagram, which statement best describes what happens
when air begins to escape from the balloon?
A. moves in the same direction as the released air
B. moves in the opposite direction to the released air
C. moves straight downward
D. stays in the same spot
E. breaks and doesn't move
正解:B
