1. What is the correct plural of chair?

• A. Chair
• B. Chairs
• C. Chaires
• D. Chairies

Correct answer: B

Rationale: The correct plural form of 'chair' is 'chairs,' following the regular pluralization rule by adding 's.' Choices C and D, 'Chaires' and 'Chairies,' are incorrect because they do not follow the standard English pluralization rule. Choice A, 'Chair,' is the singular form and not the plural form of the word.

2. Which of the following structures in the skin is responsible for producing sweat?

• A. Sebaceous gland
• B. Sudoriferous gland
• C. Hair follicle
• D. Melanocyte

Correct answer: B

Rationale: The correct answer is B: Sudoriferous gland. Sudoriferous glands, also known as sweat glands, are responsible for producing sweat to regulate body temperature. Sebaceous glands produce sebum (oil) to lubricate the skin and hair. Hair follicles are associated with hair growth, not sweat production. Melanocytes are responsible for producing melanin for skin pigmentation, not sweat.

3. Based on the language in the passage, which one of the following scenarios is correct?

• A. The writer is a professional in a business environment.
• B. The writer is a researcher writing for a scientific journal.
• C. The writer is a student writing a first draft of a paper.
• D. The writer is an author of literature.

Correct answer: D

Rationale: The correct answer is D. The passage's descriptive and narrative style, focusing on character and setting details, suggests that the writer is an author of literature. Choice A is incorrect because there is no indication of a business environment or professional context in the passage. Choice B is incorrect as the passage does not align with the technical or formal language typical of scientific journals. Choice C is incorrect as the passage does not reflect the style or content common in student papers, which are usually more structured and formal.

4. A circular swimming pool has a circumference of 49 feet. What is the diameter of the pool?

• A. 15.6 feet
• B. 17.8 feet
• C. 49 feet
• D. 153.9 feet

Correct answer: A

Rationale: The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter. Given C = 49 feet, we can rearrange the formula to solve for d: 49 feet = πd. To find the diameter, we divide both sides by π, giving us d = 49 feet / π ≈ 15.6 feet. Therefore, the diameter of the swimming pool is approximately 15.6 feet. Choices B, C, and D are incorrect because they do not align with the calculation based on the formula for the circumference of a circle.

5. Simplify the following expression: 5 x 3 ÷ 9 x 4

• A. 5/12
• B. 8/13
• C. 20/27
• D. 47/36

Correct answer: A

Rationale: To simplify the expression 5 x 3 ÷ 9 x 4, first perform the multiplications and divisions from left to right: 5 x 3 = 15 and 9 x 4 = 36. So, the expression becomes 15 ÷ 36. When dividing fractions, multiply the first fraction by the reciprocal of the second fraction. Hence, 15 ÷ 36 = 15/36. To simplify the fraction further, find the greatest common divisor, which is 3. Divide both the numerator and denominator by 3 to get the final result: 15/36 = 5/12. Therefore, the correct answer is A. Choices B, C, and D are incorrect because they do not represent the correct simplification of the given expression.
