Franz and Myra conducted an experiment to determine whether saltwater affected the growth of bean plants. They used five groups of plants. For two weeks, they gave each group the same amount of water; however, they mixed different amounts of salt into each of the five solutions. The graph below indicates the conditions and results of Franz and Myra's experiment.
Geothermal energy is one of the several alternative energy forms that may lessen our dependence on fossil fuels, such as coal and oil. In a geothermal process, hot water and steam from an underground geothermal reservoir are brought up to Earth's surface. The heated water is then used to heat homes directly or to generate electrical power. The used geothermal water is returned to the reservoir to be used again.
Based on the information, which statement provides the best conclusion about geothermal energy?
A. seldom near large bodies of water
B. sources of air pollution
C. potential sources of electrical power
D. usually in mountainous areas
E. instant sources of electrical power
正解：C
質問 2：
A limiting factor is a condition in the environment that may prevent an increase in the size of the population.
Which condition is least likely to be a limiting factor?
A. disease
B. predators
C. wind
D. drought
E. food supply
正解：C
質問 3：
Catalysts are chemical substances that increase the rate of a chemical reaction but are not changed by the reaction. Enzymes are special catalysts produced in body cells and are composed of proteins.
Which statement is true?
A. All enzymes are catalysts.
B. All proteins are catalysts.
C. All catalysts are enzymes.
D. All proteins are enzymes.
E. All catalysts are proteins.
正解：A
質問 4：
Until the mid-nineteenth century, sanitary conditions in hospitals were poor. In 1878, a large percentage of surgical patients developed infections, and many of them died. British physician Joseph Lister devised a method to sterilize the hospital operating room to prevent infection in surgical patients. Lister made sure that all the materials and instruments in the operating room were washed with a strong disinfectant called carbolic acid. As more doctors started to use Lister's procedure, the number of surgical patients who developed infections dropped dramatically.
Based on the information, which statement best explains the effectiveness of Lister's method?
A. Washing the operating rooms with a disinfectant caused more infections to develop.
B. Joseph Lister performed the first surgery in England in 1878.
C. The carbolic acid aided the growth of infectious bacteria.
D. Patients died because doctors operated on the wrong body structure.
E. The disinfectant killed the microbes that were causing the patients' infections.
正解：E
質問 5：
Exhibit:
Based on the information and diagram, which antibiotic would be most effective to use in treating the patient?
A. the antibiotic in section A
B. the antibiotic in section C
C. the antibiotic in section B
D. the antibiotic in section D
E. The antibiotics in sections A and C are equally effective.
正解：A

The pH scale has a range of 0-14. A pH of 7 is the neutral point. The acid range is less than 7. The basic range is greater than 7. Indicators are chemicals that in a solution change color to indicate an approximate pH. The indicator litmus is red in the acid range and blue in the basic range. The diagram below shows the pH scale and the pH values of several common substances.

The figure below illustrates a workman pushing a box up an inclined plane (ramp). The ramp gives the workman a mechanical advantage (MA) and requires less effort. This setup provides an MA, which represents the length of the ramp's slope (4 meters) divided by its height (1 meter).
Exhibit:
How would you increase the MA of the ramp for this worker?
A. Increase the height of the box.
B. Increase the length of the ramp.
C. Increase the length of the cart.
D. Increase the height of the ramp.
E. Pull the box.
