1. Which of the following represents the approximate combined use (in quads) of natural gas and oil in 1997?
A) 58
B) 36
C) 22
D) 28
E) 72
2. A liquid's boiling point is the temperature at which the pressure of its escaping vapor is equal to the atmospheric pressure.
Reduced pressure on the surface of a liquid results in a reduction in the vapor pressure needed for boiling to occur. At higher elevations, thinner air causes a reduction in atmospheric pressure, and liquids boil at lower temperatures.
At lower elevations, the atmospheric pressure is higher, and liquids boil at higher temperatures.
If Diane boiled water for coffee while camping in the mountains, which statement best describes what would happen to the water?
A) boil at the same temperature as it would at a lower elevation
B) not boil at the high elevation in the mountains
C) boil at a lower temperature than it would at a lower elevation
D) boil at a higher temperature than it would at a lower elevation
E) change to steam before it had a chance to boil
3. Based on the information and diagram, which container has the most thermal energy?
A) A
B) C

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 will crash because nothing is holding it up.
B) A major change in one force would not affect the plane's motion or position.
C) The plane is weightless.
D) The plane is in a state of equilibrium.
E) The plane is slowing down.
5. 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) Bacteria become resistant to treatment by certain antibiotics.
E) Time constraints prevent doctors from writing as many prescriptions.
