1. A car is accelerating down a hill. Which of the following forces is NOT acting on the car?

• A. Gravitational force
• B. Normal force from the road
• C. Air resistance
• D. The car's engine force

Correct answer: B

Rationale: When a car is accelerating down a hill, the normal force from the road is not acting on the car. The normal force is the force exerted by a surface to support the weight of an object resting on it. As the car moves downhill, the normal force decreases since the road is no longer pushing back against the car's weight due to the downhill motion. Gravitational force pulls the car downhill, air resistance opposes the car's motion, and the car's engine force propels it forward. Therefore, the correct answer is B, as the normal force from the road is not acting on the car while it accelerates downhill.

2. Where can you typically find the thesis statement of an essay?

• A. Conclusion
• B. Introduction
• C. Body paragraph
• D. Bibliography

Correct answer: B

Rationale: The thesis statement of an essay is usually located in the introduction. This is where the author establishes the main idea or argument that will be developed throughout the essay. The conclusion (Choice A) summarizes the main points and restates the thesis but does not introduce it. Body paragraphs (Choice C) provide supporting details and arguments, while the bibliography (Choice D) lists the sources used in the essay, not the thesis statement.

3. The patient was experiencing intraocular pressure. Based on the analysis of word parts, what is the meaning of 'intraocular' as used in the sentence above?

• A. Within the eyes
• B. Between the eyes
• C. Above the eyes
• D. Below the eyes

Correct answer: A

Rationale: The term 'intraocular' is derived from 'intra-' meaning within and 'ocular' referring to the eyes. Therefore, 'intraocular' means within the eyes. Choice A is correct. Choices B, C, and D are incorrect as they do not accurately reflect the meaning of 'intraocular' based on the analysis of word parts.

4. Which type of nutrients require minimal digestion before absorption?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Vitamins

Correct answer: D

Rationale: A) Carbohydrates: Carbohydrates require digestion by enzymes in the mouth, stomach, and small intestine before they can be broken down into simple sugars for absorption. B) Proteins: Proteins need to be broken down into amino acids by stomach acid and digestive enzymes in the stomach and small intestine before they can be absorbed. C) Fats: Fats require bile from the gallbladder to emulsify them into smaller droplets for enzymes to break them down into fatty acids and glycerol for absorption. D) Vitamins: Vitamins are organic compounds that are already in a form that can be readily absorbed by the body without extensive digestion. They are absorbed directly into the bloodstream from the small intestine and do not require significant breakdown before absorption.

5. What is the primary function of the liver related to digestion?

• A. Produces bile
• B. Stores bile
• C. Converts waste ammonia into urea
• D. Filters and detoxifies digestion byproducts

Correct answer: D

Rationale: The primary function of the liver related to digestion is to filter and detoxify byproducts of digestion, including toxins and metabolic waste products. While the liver does produce bile and convert waste ammonia into urea, these functions are not directly related to digestion. Storing bile is mainly done by the gallbladder, not the liver.
