1. Which type of waves travel by causing particles in the medium to vibrate parallel to the direction of wave travel?

• A. Transverse waves
• B. Longitudinal waves
• C. Surface waves
• D. Electromagnetic waves

Correct answer: B

Rationale: Longitudinal waves are waves in which particles of the medium vibrate parallel to the direction of wave travel. These waves are characterized by compressions and rarefactions in the medium, where particles move back and forth in the same direction as the wave. Transverse waves, on the other hand, cause particles to vibrate perpendicular to the direction of wave travel. Surface waves combine both longitudinal and transverse motion, making them different from pure longitudinal waves. Electromagnetic waves, unlike longitudinal and transverse waves, do not require a medium and can travel through a vacuum.

2. When it gets warm in the spring, _______ and _______ like to go fishing at Cobbs Creek. Which of the following word pairs should be used in the blanks above?

• A. me, him
• B. he, I
• C. him, I
• D. he, me

Correct answer: C

Rationale: The correct word pair to use in this context is 'him, I.' This is because 'him' and 'I' are the correct pronouns to refer to two individuals in the third person (him) and first person (I). The sentence should indicate that when it gets warm in the spring, 'him' and 'I' like to go fishing at Cobbs Creek. Choice A, 'me, him,' is incorrect as 'me' should be replaced with 'I' to maintain proper subject-object agreement. Choice B, 'he, I,' is incorrect as 'he' should be replaced with 'him' to properly refer to the other person involved. Choice D, 'he, me,' is incorrect as 'me' should be replaced with 'I' to maintain the correct pronoun usage.

3. What is the main point of dispute between the politicians?

• A. Spending on social welfare programs increases the national debt.
• B. Certain classes of people rely on social welfare programs to meet their basic needs.
• C. Certain classes of people would be irreparably harmed if the country failed to provide a social welfare program.
• D. All of the country's leaders have bootstrapped their way to the top.

Correct answer: B

Rationale: The main point of dispute between the conservative and liberal politicians is about whether certain classes of people rely on social welfare programs to meet their basic needs. The conservative politician believes that no citizens truly need government assistance and that it only makes things easier, while the liberal politician argues that various groups, such as immigrants, single mothers, and the elderly, require a safety net for basic necessities. Choice A is incorrect as it refers to the impact on national debt, which is not the primary point of dispute. Choice C is incorrect as it discusses the consequences of failing to provide social welfare programs, not the main point of disagreement. Choice D is irrelevant as it talks about the backgrounds of the country's leaders, which is not the focus of the dispute between the politicians.

4. Where is oxygen exchanged between blood and tissues?

• A. capillaries
• B. veins
• C. ventricles
• D. arteries

Correct answer: A

Rationale: Oxygen is exchanged between blood and tissues primarily at the capillaries. Capillaries are the smallest blood vessels where the exchange of oxygen, nutrients, and waste products occurs between the blood and the tissues. This exchange process is crucial for delivering oxygen to the body's cells and eliminating carbon dioxide waste. Veins carry blood back to the heart, arteries carry blood away from the heart, and ventricles are the lower chambers of the heart responsible for pumping blood. Therefore, capillaries are the correct answer for where oxygen is exchanged between blood and tissues.

5. A recipe calls for 5.5 teaspoons of vanilla. 1 teaspoon equals approximately 4.93 mL. Which of the following is the correct amount of vanilla in mL?

• A. 10.2 mL
• B. 12 mL
• C. 7.43 mL
• D. 27 mL

Correct answer: D

Rationale: To convert the amount of vanilla from teaspoons to milliliters, we multiply the number of teaspoons by the conversion factor of 4.93 mL/teaspoon. 5.5 teaspoons * 4.93 mL/teaspoon = 27.115 mL, which rounds to 27 mL. Therefore, the correct amount of vanilla in mL is 27 mL. Choice A (10.2 mL), Choice B (12 mL), and Choice C (7.43 mL) are incorrect as they do not correctly convert the given amount of teaspoons to milliliters based on the provided conversion factor.
