1. During vigorous exercise, why does the respiratory rate increase?

• A. Meet the increased demand for oxygen in working muscles
• B. Eliminate excess carbon dioxide more slowly
• C. Conserve energy for physical activity
• D. Decrease the amount of oxygen delivered to the body

Correct answer: A

Rationale: During vigorous exercise, the muscles require more oxygen to produce energy for physical activity. The increased respiratory rate helps to deliver more oxygen to the working muscles to meet this demand. This process is essential for sustaining physical activity and preventing fatigue. Choice A is the correct answer as it accurately describes the purpose of the increased respiratory rate during vigorous exercise. Choices B, C, and D are incorrect. Choice B, 'Eliminate excess carbon dioxide more slowly,' is inaccurate as the primary reason for the increased respiratory rate during exercise is to meet the increased demand for oxygen, not to eliminate carbon dioxide. Choice C, 'Conserve energy for physical activity,' is incorrect because increasing the respiratory rate actually expends energy to meet the oxygen demand of the working muscles. Choice D, 'Decrease the amount of oxygen delivered to the body,' is incorrect as the increased respiratory rate is specifically to deliver more oxygen to the body during exercise.

2. What kinds of clauses does the following sentence contain? "Although Ted had an impressive education, he had little experience working with individuals, which made him less effective at relating to them."

• A. Two dependent clauses and one independent clause
• B. One dependent clause and two independent clauses
• C. Two independent clauses and no dependent clauses
• D. One dependent clause and one independent clause

Correct answer: B

Rationale: The sentence consists of one dependent clause, 'Although Ted had an impressive education,' which introduces a condition. It also contains two independent clauses: 'he had little experience working with individuals,' which presents a fact, and 'which made him less effective at relating to them,' which provides additional information. Therefore, the correct answer is B. Choice A is incorrect because it incorrectly identifies the number of independent and dependent clauses. Choice C is incorrect as it wrongly states that there are no dependent clauses in the sentence. Choice D is incorrect as it does not accurately represent the structure of the sentence.

3. A student reads the following sentence: A hundred years ago, automobiles were rare, but now cars are ubiquitous. However, she doesn't know what the word ubiquitous means. Which key context clue is essential to decipher the word's meaning?

• A. Ago
• B. Cars
• C. Now
• D. Rare

Correct answer: C

Rationale: The key context clue essential to decipher the word 'ubiquitous' is the word 'now.' By comparing the rarity of automobiles a hundred years ago to their ubiquity now, the student can infer that 'ubiquitous' means something that is commonplace or found everywhere. Choice A ('Ago') refers to the past and does not provide information about the current state of cars. Choice B ('Cars') only contrasts rare and ubiquitous without indicating the change over time. Choice D ('Rare') simply contrasts with 'ubiquitous' without showing the transition from rarity to ubiquity.

4. Adam is painting the outside of a 4-walled shed. The shed is 5 feet wide, 4 feet deep, and 7 feet high. Which of the following is the amount of paint Adam will need for the four walls?

• A. 80 ft²
• B. 126 ft²
• C. 140 ft²
• D. 560 ft²

Correct answer: B

Rationale: To find the amount of paint needed for the four walls of the shed, calculate the total area of the four walls. The shed has two pairs of identical walls. The area of one pair of walls is 5 feet (width) x 7 feet (height) + 4 feet (depth) x 7 feet (height) = 35 ft² + 28 ft² = 63 ft². Since there are two pairs of walls, the total area for the four walls is 2 x 63 ft² = 126 ft². Therefore, Adam will need 126 ft² of paint for the four walls. Choice A, 80 ft², is incorrect as it does not account for the total surface area of all four walls. Choice C, 140 ft², is incorrect as it overestimates the area required. Choice D, 560 ft², is incorrect as it significantly overestimates the amount of paint needed for the shed.

5. His charismatic personality, organizational abilities, sheer determination, and rhetorical skills enabled him to quickly rise through the chapter’s ranks. Which of the following revisions maintains the correct tense?

• A. NO CHANGE
• B. are enabling him to quickly rise
• C. enabled him to quickly rise
• D. will enable him to quickly rise

Correct answer: C

Rationale: Choice C, 'enabled him to quickly rise,' is the correct answer as it maintains the past tense to match the context of the sentence. The sentence describes actions that have already occurred, so the past tense 'enabled' is appropriate. Choice A is incorrect as it does not provide the correct tense for the sentence. Choice B is incorrect as it uses the present continuous tense, which is not suitable for the context of the sentence. Choice D is incorrect as it uses the future tense, which does not align with the past actions described in the sentence.
