1. Due to his many interests and pursuits, Eratosthenes dabbled in a variety of fields, and he is credited with a theory known as the sieve of Eratosthenes. This is an early algorithm used to determine prime numbers. To which section of the library should Jorgen go to find out more about the current applications of the sieve of Eratosthenes?

• A. 0
• B. 100
• C. 400
• D. 500

Correct answer: D

Rationale: Jorgen should go to the 500 section of the library, which is dedicated to science and mathematics. The sieve of Eratosthenes is a mathematical concept, so current applications and research related to it would be found in this section. Choice A (0) is incorrect as it is for general works. Choice B (100) is for philosophy and psychology, which are unrelated to mathematics. Choice C (400) is for languages, not mathematics.

2. Which of the following is an example of a chemical change?

• A. Dissolving sugar in water
• B. Boiling water
• C. Rusting iron
• D. Crushing ice

Correct answer: C

Rationale: Rusting iron is an example of a chemical change because it involves a chemical reaction where iron reacts with oxygen in the presence of water to form iron oxide (rust). This reaction results in a change in the chemical composition of the iron, unlike dissolving sugar in water, boiling water, or crushing ice, which are physical changes. Dissolving sugar in water is a physical change as sugar molecules remain unchanged but disperse in water. Boiling water is also a physical change as water changes its state from liquid to gas due to heat. Crushing ice is a physical change as the solid ice changes its physical form without altering its chemical composition.

3. Which part of the brain is responsible for controlling involuntary actions like breathing and heart rate?

• A. Cerebellum
• B. Medulla oblongata
• C. Cerebrum
• D. Thalamus

Correct answer: B

Rationale: The correct answer is the Medulla oblongata. This region of the brain is located in the brainstem and is responsible for controlling vital autonomic functions such as breathing, heart rate, and blood pressure. The Cerebellum (Choice A) is primarily involved in coordination and balance. The Cerebrum (Choice C) is responsible for higher brain functions like thinking and voluntary muscle movement. The Thalamus (Choice D) acts as a relay station for sensory information but is not primarily responsible for controlling involuntary actions like breathing and heart rate.

4. 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.

5. Which of the following is a characteristic of a solution with high viscosity?

• A. It flows easily
• B. It has a low resistance to flow
• C. It has a high resistance to flow
• D. It does not mix with other liquids

Correct answer: C

Rationale: The correct answer is C: 'It has a high resistance to flow.' A solution with high viscosity exhibits a high resistance to flow. Viscosity measures the fluid's resistance to deformation or flow, with higher viscosity indicating thicker and slower-flowing fluids. Choice A is incorrect because high viscosity means the solution flows slowly, not easily. Choice B is incorrect as high viscosity implies a high resistance to flow, not a low one. Choice D is irrelevant to viscosity and does not describe a characteristic associated with high viscosity.
