1. John’s Gym charges its members according to the equation y = 40x, where x is the number of months and y represents the total cost to each customer after x months. Ralph’s Recreation Room charges its members according to the equation y = 45x. What relationship can be determined about the monthly cost to the members of each company?

• A. John’s monthly membership fee is equal to Ralph’s monthly membership fee.
• B. John’s monthly membership fee is more than Ralph’s monthly membership fee.
• C. John’s monthly membership fee is less than Ralph’s monthly membership fee.
• D. No relationship can be determined between the monthly membership fees.

Correct answer: C

Rationale: The equation y = 40x represents John's Gym charging $40 per month, while the equation y = 45x represents Ralph's Recreation Room charging $45 per month. Since $40 is less than $45, it can be concluded that John's Gym offers a lower monthly membership fee compared to Ralph's Recreation Room. Therefore, the correct answer is that John’s monthly membership fee is less than Ralph’s monthly membership fee. Choices A and B are incorrect because John's fee is not equal to or greater than Ralph's fee. Choice D is incorrect as there is a clear relationship indicating that John’s monthly membership fee is less than Ralph’s monthly membership fee.

2. Which of the following is the outermost layer of the skin, providing protection against pathogens and the environment?

• A. Dermis
• B. Epidermis
• C. Hypodermis
• D. Stratum corneum (part of the epidermis)

Correct answer: B

Rationale: The epidermis is the correct answer as it is the outermost layer of the skin, providing protection against pathogens and the environment. It consists of multiple layers, including the stratum corneum, which is the outermost layer of the epidermis. The dermis is located beneath the epidermis, offering structural support and housing blood vessels, nerves, and glands. The hypodermis is the deepest layer of the skin, made up of fat and connective tissue that secures the skin to underlying structures. Choice A, Dermis, is incorrect as it is located beneath the epidermis. Choice C, Hypodermis, is incorrect as it is the deepest layer of the skin, not the outermost. Choice D, Stratum corneum (part of the epidermis), is not the correct answer as it is a specific layer within the epidermis and not the overall outermost layer of the skin.

3. When proofreading your writing, what should be your primary focus?

• A. Changing the wording to enhance originality.
• B. Avoiding minor grammatical errors like typos.
• C. Checking for clarity, consistency, and overall flow.
• D. Avoiding replacing common words with thesaurus alternatives.

Correct answer: C

Rationale: When proofreading your writing, the primary focus should be on checking for clarity, consistency, and overall flow. This involves ensuring that the content is clear, logical, and flows smoothly from one point to the next. While enhancing originality can be important, it is secondary to ensuring that the writing effectively communicates its message. Ignoring minor grammatical errors like typos can detract from the professionalism and impact of the writing. Replacing common words with thesaurus alternatives should be done sparingly and only when it enhances the clarity or impact of the text, rather than as a routine practice during proofreading.

4. A certain exam has 30 questions. A student gets 1 point for each question answered correctly and loses half a point for each question answered incorrectly; no points are gained or lost for questions left blank. If x represents the number of questions a student answers correctly and y represents the number of questions left blank, which of the following expressions represents the student's score on the exam?

• A. x - y/2
• B. x - y
• C. 30 - (x + y)
• D. 30 - x - y/2

Correct answer: A

Rationale: The student's score is calculated by adding the points earned for correct answers (x) and subtracting the points lost for incorrect answers (y/2). Therefore, the expression for the student's score on the exam is x - y/2. Option A is correct because it accurately represents this calculation. Option B (x - y) is incorrect as it does not account for the penalty of losing half a point for each incorrect answer. Option C (30 - (x + y)) is incorrect as it subtracts the total number of questions from the sum of correct and blank answers, which does not represent the scoring system. Option D (30 - x - y/2) is also incorrect as it incorrectly subtracts x from 30 and then deducts y divided by 2, which is not the correct scoring method for the exam.

5. Why does the author say it is important to buy locally grown food?

• A. Buying locally grown food supports people in your community.
• B. Locally grown food travels the least distance to reach you and therefore uses fewer resources.
• C. Locally grown food uses less packaging.
• D. Locally grown food is healthier for you because it has been exposed to fewer pesticides.

Correct answer: B

Rationale: The author stresses the significance of buying locally grown food due to its minimal travel distance, which results in reduced resource utilization. This aligns with the passage's primary environmental theme of conserving resources for the future. Choice A is incorrect because although buying locally grown food can support the community, the main focus in the passage is on resource conservation. Choice C is incorrect as the passage emphasizes the importance of packaging but does not specifically mention that locally grown food uses less packaging. Choice D is incorrect as the health aspect related to fewer pesticides is not discussed in the passage regarding the importance of buying locally grown food.
