1. What property best describes the characteristic that nuclear forces are much stronger than electromagnetic forces at the nuclear level?

• A. Short-range interaction
• B. Long-range interaction
• C. Repulsive force
• D. Dependent on charge only

Correct answer: A

Rationale: The correct answer is A: Short-range interaction. Nuclear forces are much stronger than electromagnetic forces at the nuclear level because they are short-range interactions that act over distances on the order of the size of an atomic nucleus. This short-range nature of nuclear forces allows them to be much stronger than the long-range electromagnetic forces, which weaken with distance according to the inverse square law. Choice B, long-range interaction, is incorrect because nuclear forces are short-range. Choice C, repulsive force, is incorrect as nuclear forces include both attractive and repulsive components. Choice D, dependent on charge only, is incorrect because nuclear forces are not solely determined by charge but also involve other factors like spin and isospin.

2. Which of the following best describes the theme of the passage?

• A. Patronizing
• B. Skeptical
• C. Objective
• D. Nostalgic

Correct answer: C

Rationale: The correct answer is C: 'Objective.' The passage presents a factual account of Clara Barton's life events without showing bias or personal feelings. The text outlines significant milestones in Barton's life chronologically, from her birth to her contributions during and after the Civil War, culminating in her advocacy for the establishment of an American branch of the International Red Cross Organization. The passage does not exhibit a patronizing tone (choice A), as it does not talk down to Barton or belittle her achievements. It is also not skeptical (choice B), as it does not express doubt or disbelief in the information presented. Furthermore, the passage is not nostalgic (choice D), as it does not dwell on sentimental feelings or memories of the past. Therefore, 'Objective' is the most suitable description of the passage's theme.

3. Passive transport does not require energy input from the cell. Which of the following is an example of passive transport?

• A. Active transport of ions across a membrane
• B. Diffusion of small molecules across a concentration gradient
• C. Movement of large molecules using vesicles
• D. Endocytosis of particles into the cell

Correct answer: B

Rationale: Passive transport refers to the movement of molecules across a cell membrane without the input of energy. Diffusion of small molecules across a concentration gradient is a classic example of passive transport, as it occurs spontaneously from an area of high concentration to an area of low concentration. Active transport (option A) requires energy input in the form of ATP to move substances against their concentration gradient. Movement of large molecules using vesicles (option C) involves processes like endocytosis and exocytosis that require energy in the form of ATP. Endocytosis of particles into the cell (option D) is an active process that requires energy expenditure by the cell to engulf and internalize extracellular substances.

4. What happens to the acceleration of an object when the force acting on it is increased, assuming the mass remains constant?

• A. Acceleration increases
• B. Acceleration decreases
• C. Acceleration remains constant
• D. Acceleration becomes zero

Correct answer: A

Rationale: According to Newton's second law of motion, acceleration is directly proportional to the force acting on an object when the mass is constant. Therefore, if the force acting on an object is increased while the mass remains constant, the acceleration of the object will also increase. This relationship is described by the formula F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration. When force increases, acceleration increases, and vice versa, as long as the mass stays the same. Choice B (Acceleration decreases) is incorrect because acceleration and force have a direct relationship. Choice C (Acceleration remains constant) is incorrect because acceleration changes in response to changes in force. Choice D (Acceleration becomes zero) is incorrect because increasing force does not make acceleration zero; it actually increases it.

5. Which organizational style is used in the following passage?

• A. Cause and effect order
• B. Compare and contrast order
• C. Spatial order
• D. Time order

Correct answer: A

Rationale: The passage uses a cause and effect order to explain the reasons for the cafe's lack of success. It presents causes (higher prices and early closure) first, followed by their effects (students unable to afford food and beverages, students going elsewhere). This structure helps readers understand the relationship between the causes and their resulting effects. Choice B, 'Compare and contrast order,' is incorrect as the passage does not focus on comparing different aspects or contrasting ideas. Choice C, 'Spatial order,' is incorrect as it does not describe physical locations or arrangements. Choice D, 'Time order,' is incorrect as the passage does not primarily follow a chronological sequence of events.
