1. Which word in the passage shows that the plunger is depressed and air is pushed out at the same time?

• A. Out
• B. Continued
• C. As
• D. Causes

Correct answer: C

Rationale: The correct answer is 'C: As.' In the provided extract, the word 'As' is used to indicate the simultaneous action of depressing the plunger and pushing out the air. It establishes a connection between the two actions, showing that they occur together. Choice A, 'Out,' refers to the result of pushing the air out, not the action happening simultaneously. Choice B, 'Continued,' suggests a subsequent action rather than a simultaneous one. Choice D, 'Causes,' indicates a cause-and-effect relationship, not the action happening simultaneously like the word 'As' does.

2. What is the scientific term for scar tissue?

• A. Epithelial tissue
• B. Fibrous connective tissue
• C. Cartilage
• D. Adipose tissue

Correct answer: B

Rationale: The correct scientific term for scar tissue is fibrous connective tissue. Scar tissue is primarily composed of fibrous connective tissue, which forms as part of the body's natural healing process in response to injury or trauma. Epithelial tissue, cartilage, and adipose tissue are not typically involved in scar formation. Therefore, the correct answer is fibrous connective tissue, as it is the specific type of tissue that makes up scar tissue.

3. Where does gas exchange occur in the human body?

• A. Alveoli
• B. Bronchi
• C. Larynx
• D. Pharynx

Correct answer: A

Rationale: The correct answer is A: Alveoli. Gas exchange occurs in the alveoli, which are tiny air sacs in the lungs. Oxygen from the air we breathe diffuses into the blood vessels surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. The bronchi, larynx, and pharynx are all part of the respiratory system but are not directly involved in gas exchange. The bronchi are airways that lead to the lungs, the larynx is the voice box, and the pharynx is the throat. These structures are important for breathing and vocalization but do not participate in the exchange of gases between the respiratory system and the circulatory system.

4. Melissa is ordering fencing to enclose a square area of 5625 square feet. How many feet of fencing does she need?

• A. 75 feet
• B. 150 feet
• C. 300 feet
• D. 5,625 feet

Correct answer: C

Rationale: To find the side length of the square, we take the square root of the area: √5625 ft² = 75 ft. The perimeter of a square is 4 times its side length, so the fencing needed is 4 × 75 ft = 300 ft. Therefore, Melissa needs 300 feet of fencing to enclose the square area of 5625 square feet. Option A (75 feet) is the side length of the square, not the fencing needed. Option B (150 feet) is half of the correct answer and does not account for all sides of the square. Option D (5,625 feet) is the total area, not the length of fencing required.

5. Every morning we would wake up, eat breakfast, and break camp. Which of the following is the correct revision for the sentence?

• A. NO CHANGE
• B. we would wake up, eat breakfast, and break camp.
• C. would we wake up, eat breakfast, and break camp?
• D. we are waking up, eating breakfast, and breaking camp.

Correct answer: B

Rationale: The correct answer is B: 'we would wake up, eat breakfast, and break camp.' The original sentence is a list of actions in the past, so the verb 'break' should also be in the past tense to maintain consistency. Choice A is incorrect because 'broke' is incorrect in this context. Choice C is a question format and does not fit the original sentence structure. Choice D changes the tense to present progressive, which does not match the past tense context of the sentence.
