質問 1：
Line spectra, a series of bright lines, are shown above for several elements. Scientists find these spectral lines, which are essentially a set of chemical "fingerprints," to be useful for the identification of elements. Each element produces a unique series of spectral lines referred to as an emission spectrum. An unknown sample can be identified by matching spectral lines with those of a known element.

Based on the information and diagram, which element is present in the sample shown on the left?
A. sodium
B. argon
C. helium
D. hydrogen
E. calcium
正解：C

質問 2：
Detergents, which are often kept in low places where their brightly colored containers can attract young children, account for more poisonings in the home than any other product. Part of the problem is that consumers do not recognize the difference between synthetic detergents, which are poisonous, and ordinary soaps, which are not.
The passage above would most likely come from a book that has which of the following titles?
A. Mechanics for the Home Hobbyist
B. Radon: How to Rid Your Home of the Danger
C. Decorating Tips for Your Home
D. Chemistry: The Study of Matter
E. A Guide to Household Pollutants
正解：E

質問 3：
Exhibit:

Based on the information, which statement would explain this fact?
A. Sound travels fastest through a solid material.
B. Sound consists of vibrations in any material.
C. Striking an object will start it vibrating.
D. The vibrations of a solid object will start air molecules vibrating.
E. Rails effectively absorb and deaden the sound.
正解：A

質問 4：
As plants grow, they absorb nutrients from the soil. Plant leaves can be carefully observed to determine the relative healthiness of the plant and whether it is suffering from a nutrient deficiency. The chart below shows the most common nutrient deficiencies and their effects on plant leaves.
A plant has leaves that are yellowing at the tips and margins with dead spots on the leaves.

Which substance should be added to the soil to correct this condition?
A. phosphorus
B. magnesium
C. nitrogen
D. potassium
E. calcium
正解：D

質問 5：
-- Exhibit -
The carbon cycle is illustrated above. Two of the essential processes involved are photosynthesis in green plants and algae and respiration by almost all organisms. Respiration, as well as burning and other natural decomposition (breakdown) processes, contributes to the amount of CO2 in the air and soil. Photosynthesis uses up CO2 and produces O2, which, in turn, is used up in respiration and the burning of fossil fuels such as coal, oil, and gas.

-- Exhibit -
Based on the information and diagram, which process does not release CO2?
A. human respiration
B. photosynthesis
C. auto exhaust
D. animal respiration
E. burning fossil fuels
正解：B

質問 6：
Susan is studying air pressure and makes a simple mercury barometer as shown below. She knows that air exerts pressure. More pressure on the surface of the mercury in the bowl will cause the mercury level to rise. Less pressure will cause the mercury to fall. High barometric pressure is often associated with fair weather, and low barometric pressure is associated with rain.
Susan is enjoying a bright, sunny day when she hears a local weather forecaster predict rain for tomorrow.

When Susan checks her barometer tomorrow, which change is she most likely to note?
A. have risen by about 5%
B. totally fill the tube
C. have risen by more than 10%
D. remain unchanged
E. have fallen
正解：E

質問 7：
Exhibit:

Based on the information and diagram, which slide shows the most positive response of paramecia to a stimulus?
A. slide E
B. slide C
C. slide D
D. slide B
E. slide F
正解：A
