1. Based on the scenario provided, which of the following inferences can be validly made?

• A. This director consistently produces unsuccessful movies.
• B. Movie reviews have no impact on the success of a film.
• C. The movie reviewers' assessments of the first movie were correct.
• D. The director's next movie will receive positive reviews.

Correct answer: C

Rationale: Choice C is the correct answer because the scenario indicates that the negative reviews of the first movie were accurate, as the subsequent poor performance of the movie aligns with the critics' assessments. Choices A and D are incorrect as the scenario only provides information about the first movie and its repercussions, not about the director's consistent performance or the future reception of their movies. Choice B is incorrect because the scenario clearly demonstrates that negative reviews had a significant impact on the movie's performance, contradicting the idea that movie reviews have no influence.

2. The Black Panther Party (BPP) was another activist group that formed around the same time as and was similar in function to the NAACP. What revision best improves this sentence?

• A. NO CHANGE
• B. was another activist group that
• C. had a lot of members that
• D. was another school that

Correct answer: B

Rationale: Describing the BPP as 'another activist group' provides clarity and relevance. Choice B correctly identifies the Black Panther Party as an activist group, aligning with its historical context and function. Choices C and D introduce irrelevant or inaccurate information, making them incorrect. Choice A, 'NO CHANGE,' leaves the sentence vague and does not provide the necessary clarification about the nature of the Black Panther Party.

3. What is the role of hemoglobin in the human body?

• A. Transport oxygen in red blood cells
• B. Bind oxygen to red blood cells
• C. Carry carbon dioxide from tissues to lungs
• D. Help red blood cells transport oxygen

Correct answer: D

Rationale: The correct answer is D: 'Help red blood cells transport oxygen.' Hemoglobin acts as a carrier molecule in red blood cells, binding to oxygen in the lungs and releasing it in the tissues. It facilitates the transport of oxygen from the lungs to the tissues and aids in returning carbon dioxide from the tissues to the lungs. Choices A, B, and C are incorrect because hemoglobin itself does not transport oxygen independently or bind oxygen to red blood cells nor does it carry carbon dioxide from tissues to lungs; instead, it assists red blood cells in the transportation of oxygen.

4. What is the SI unit of measurement for acceleration?

• A. Meters per second (m/s)
• B. Newton (N)
• C. Meters (m)
• D. Meters per second squared (m/s²)

Correct answer: D

Rationale: The SI unit of measurement for acceleration is meters per second squared (m/s²). Acceleration is defined as the rate of change of velocity over time. It is a vector quantity with dimensions of length per time squared. Meters per second squared (m/s²) represents the change in velocity (meters per second) over a specific time interval (seconds) squared. Choice A, meters per second (m/s), represents velocity, not acceleration. Choice B, Newton (N), is the unit of force. Choice C, Meters (m), represents only distance, not acceleration. Therefore, the correct unit for acceleration is meters per second squared (m/s²).

5. Which concentration unit depends on pressure?

• A. ppm
• B. ppb
• C. molarity
• D. molarity, ppb, and ppm

Correct answer: C

Rationale: The correct answer is 'C: molarity.' Molarity is the concentration unit that depends on pressure. In molarity, the concentration of a solution is expressed as the number of moles of solute per liter of solution. This means that changes in pressure can affect the volume of the solution and consequently the concentration. Choices A and B, ppm (parts per million) and ppb (parts per billion), respectively, are independent of pressure variations as they are based on mass ratios. Therefore, molarity is the only concentration unit listed that is directly influenced by changes in pressure.
