1. Which of the following best describes a group of cells working together?

• A. Organelle
• B. Tissue
• C. Organ
• D. Organ system

Correct answer: B

Rationale: The correct answer is B: Tissue. Tissue is a group of cells that work together to perform a specific function. Organelle refers to specialized structures within a cell, organ is a structure made up of different types of tissues working together, and organ system is a group of organs working together to perform complex functions. Therefore, tissue is the most appropriate term to describe a group of cells working together.

2. Which of the following bones is not associated with the leg?

• A. femur
• B. tibia
• C. patella
• D. radius

Correct answer: D

Rationale: The correct answer is D, radius. According to the passage, the radius is a bone in the lower arm, not in the leg. The femur, tibia, and patella are bones associated with the leg. The femur is the thigh bone, the tibia is the shin bone, and the patella is the kneecap. Therefore, the radius is the only bone among the options that is not associated with the leg.

3. Which hormone, produced by the thyroid gland, plays a key role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys?

• A. Calcitonin
• B. Parathyroid hormone (PTH)
• C. Thyroxine
• D. Insulin

Correct answer: A

Rationale: Calcitonin, produced by the thyroid gland, is responsible for regulating calcium levels in the blood. It works by decreasing blood calcium levels through two main mechanisms: promoting calcium uptake by bones and decreasing calcium reabsorption in the kidneys. Parathyroid hormone (PTH), on the other hand, increases blood calcium levels by promoting calcium release from bones and increasing calcium absorption in the intestines. Thyroxine, another thyroid hormone, primarily regulates metabolism and has no direct influence on calcium levels. Insulin, produced by the pancreas, is involved in regulating blood sugar levels and is not related to calcium homeostasis.

4. Which of the following pairs of words includes a suffix that changes the meaning of the second word from the first?

• A. fort; fortification
• B. mount; dismount
• C. flee; fleeing
• D. fame; famous

Correct answer: D

Rationale: The correct answer is D. Adding the suffix '-ous' to 'fame' changes it to an adjective, 'famous,' altering the meaning of the word. Choice A is incorrect because 'fortification' is derived from 'fort' but does not change its meaning significantly. Choice B is incorrect as 'dismount' is related to 'mount' but signifies the opposite action rather than a change in meaning. Choice C is incorrect as 'fleeing' is simply the present participle form of 'flee' and does not alter its fundamental meaning.

5. In which of the following materials would the author be most likely to include this passage?

• A. A history textbook
• B. An obituary
• C. A fictional story
• D. A newspaper editorial

Correct answer: A

Rationale: A history textbook is the most appropriate place for the passage about George Washington because it provides historical context, factual information, and analysis of significant events related to his life and contributions. The passage discusses Washington's role in the American Revolution, his leadership during the Revolutionary War, his decision to step down after the war, his farewell address, and his views on governance and foreign affairs. This type of detailed historical content is commonly found in history textbooks. Choices B, C, and D are incorrect because an obituary focuses on a person's death and life achievements in a brief manner, a fictional story is based on imagination and creativity, and a newspaper editorial typically presents opinions on current events or issues rather than historical accounts.
