1. The liver plays a vital role in digestion. What is one of the main functions of the liver in the digestive system?

• A. Physical breakdown of food
• B. Production of digestive enzymes
• C. Storage and processing of nutrients
• D. Elimination of waste products

Correct answer: C

Rationale: The correct answer is C: Storage and processing of nutrients. The liver plays a crucial role in processing nutrients absorbed from the small intestine, storing glycogen, vitamins, and minerals, and regulating blood sugar levels by releasing or storing glucose as needed. Choices A, B, and D are incorrect because the physical breakdown of food primarily occurs in the mouth and stomach, the production of digestive enzymes is mainly carried out by the pancreas and small intestine, and the elimination of waste products is primarily managed by the large intestine and kidneys, not the liver.

2. Based on the context of the passage, the reader can infer that this information is likely to appear in which of the following types of works?

• A. a scholarly paper
• B. a mystery
• C. a fictional story
• D. a biography

Correct answer: D

Rationale: The information provided in the passage about the skeleton's structure and divisions, along with specific details like the number of bones and their functions, is characteristic of content found in a biography or a reference work focusing on anatomy. Biographies often include detailed factual information about historical figures, their lives, and aspects related to them, such as physical characteristics. A scholarly paper would delve deeper into analysis and research, rather than presenting basic factual information. The content in the passage is purely informative and factual, ruling out the possibility of it being part of a mystery or fictional story, which require narrative and plot elements rather than straightforward facts.

3. Eric buys 5 1/2 pounds of apples each week for four weeks. How many total pounds does he buy?

• A. 22 pounds
• B. 20 pounds
• C. 18 pounds
• D. 24 pounds

Correct answer: A

Rationale: To find the total pounds of apples Eric buys, you need to multiply the pounds of apples bought each week (5 1/2 pounds) by the number of weeks (4 weeks). When you multiply 5 1/2 by 4, you get 22 pounds. Therefore, the correct answer is A. Choices B, C, and D are incorrect because they do not accurately calculate the total pounds purchased over the four weeks.

4. Which hormone stimulates the release of calcium from bones and increases blood calcium levels?

• A. Parathyroid hormone (PTH)
• B. Calcitonin
• C. Growth hormone
• D. Testosterone

Correct answer: A

Rationale: Parathyroid hormone (PTH) is the correct answer. PTH stimulates the release of calcium from bones, leading to increased blood calcium levels. It acts on the bones to release calcium into the bloodstream, facilitates the kidneys' reabsorption of calcium, and triggers vitamin D activation to boost calcium absorption from the intestines. Choice B, Calcitonin, is incorrect as it works in opposition to PTH by decreasing blood calcium levels through inhibiting calcium release from bones. Choices C and D, Growth hormone and Testosterone, are not directly involved in calcium homeostasis and do not regulate blood calcium levels through bone calcium release mechanisms.

5. 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.
