1. What is the fundamental unit of the nervous system?

• A. Neuron
• B. Nerve
• C. Ganglion
• D. Neuroglia

Correct answer: A

Rationale: The correct answer is A: Neuron. Neurons are the fundamental building blocks of the nervous system. These specialized cells play a crucial role in transmitting information through electrical and chemical signals. While nerves are comprised of bundles of neurons and ganglia consist of clusters of nerve cell bodies located outside the central nervous system, neuroglia serve as support cells for neurons. Neurons are specifically responsible for processing and transmitting information within the nervous system, making them the essential unit of this complex system. Choices B, C, and D are incorrect as nerves are bundles of neurons, ganglia are clusters of nerve cell bodies outside the central nervous system, and neuroglia are support cells for neurons, not the fundamental units responsible for information processing and transmission.

2. In which chapter should she look for more information on herbal remedies to combat eczema?

• A. Chapter 8
• B. Chapter 10
• C. Chapter 11
• D. Chapter 12

Correct answer: D

Rationale: Eczema is a topical condition, so Chapter 12 (section D) would be the most appropriate place to look for information on herbal remedies to combat it. Chapter 8 focuses on herbs for adult needs, and while it may contain some relevant information, it is not specific to topical conditions like eczema. Chapters 10 and 11 cover respiratory and digestive conditions respectively, which are not relevant to treating eczema. Therefore, Chapter 12 is the best choice for Clothilde to find herbal remedies to combat eczema.

3. A rectangular field has an area of 1452 square feet. If the length is three times the width, what is the width of the field?

• A. 22 feet
• B. 44 feet
• C. 242 feet
• D. 1452 feet

Correct answer: A

Rationale: To find the width of the rectangular field, use the formula for the area of a rectangle: A = length × width. Given that the length is three times the width, you have A = 3w × w. Substituting the given area, 1452 = 3w^2. Solving for w, you get 484 = w^2. Taking the square root gives ±22, but since the width must be positive, the width of the field is 22 feet. Choice B, 44 feet, is incorrect because it represents the length, not the width. Choice C, 242 feet, is incorrect as it is not a factor of the area. Choice D, 1452 feet, is incorrect as it represents the total area of the field, not the width.

4. A couple dining at a restaurant receives a bill for $58.60. They wish to leave a 16% gratuity. Which of the following is the estimated gratuity?

• A. $8.48
• B. $6.40
• C. $9.38
• D. $7.00

Correct answer: C

Rationale: To calculate a 16% gratuity on a bill of $58.60, you multiply $58.60 by 0.16, which equals $9.376. Rounding this to the nearest cent gives $9.38. Therefore, the estimated gratuity is $9.38. Choice A is incorrect as it does not accurately reflect the calculated amount. Choice B is also incorrect as it does not match the correct calculation. Choice D is incorrect as it is not the nearest estimated value to the calculated amount.

5. Which of the following literary devices is present in the excerpt?

• A. Personification
• B. Synecdoche
• C. Metaphor
• D. Colloquialism

Correct answer: D

Rationale: The correct answer is 'D: Colloquialism'. Colloquialism is the use of informal, everyday language in writing or speaking. In the given excerpt, the dialogue is informal and reflects everyday speech, making it an example of colloquialism. Choice A, 'Personification', attributes human qualities to non-human entities, choice B, 'Synecdoche', represents a part of something to refer to the whole, and choice C, 'Metaphor', implies a comparison between two unrelated things. These choices do not accurately describe the literary device present in the excerpt, making them incorrect.
