1. Which of the following best describes the author’s purpose?

• A. The author wants to tell customers about the cars available at Carl’s Car Depot.
• B. The author wants to encourage other car dealerships to lower their prices.
• C. The author wants to provide new and used cars at affordable prices.
• D. The author wants to attract customers to Carl’s Car Depot.

Correct answer: D

Rationale: The author's purpose is to attract customers to Carl's Car Depot. The text from the extract clearly emphasizes the one-day-only summer sale event at Carl’s Car Depot, highlighting the wide range of cars available at discounted prices with special financing options. The author aims to draw in potential customers by presenting compelling offers and creating a sense of urgency. Choices A, B, and C are incorrect because the primary focus is on attracting customers to Carl’s Car Depot by showcasing the available cars and the limited-time sale, not solely informing customers about the cars, urging other dealerships to lower prices, or generally providing affordable cars.

2. Which structure protects the lungs?

• A. Femur
• B. Ribcage
• C. Scapula
• D. Skull

Correct answer: B

Rationale: The ribcage is the correct answer. It protects the lungs by providing structural support and shielding them from injury. The femur is a bone in the thigh and does not protect the lungs. The scapula is a shoulder blade bone, and the skull protects the brain, not the lungs.

3. Which of the following best defines the term amphoteric?

• A. A substance that conducts electricity due to ionization when dissolved in a solvent
• B. A substance that can act as an acid or a base depending on the properties of the solute
• C. A substance that, according to the Brønsted-Lowry Acid-Base Theory, is a proton-donor
• D. A substance that donates its proton and forms its conjugate base in a neutralization reaction

Correct answer: B

Rationale: An amphoteric substance can act as both an acid or a base depending on the environment. It can donate a proton (act as an acid) or accept a proton (act as a base), showing versatility in its behavior. Choice A is incorrect as it describes an electrolyte rather than an amphoteric substance. Choice C is incorrect as it defines an acid based on the Brønsted-Lowry Acid-Base Theory. Choice D is incorrect as it specifically refers to a substance donating a proton in a neutralization reaction, not capturing the dual behavior of an amphoteric substance.

4. In the sentence, “We will depart as a class, but when we arrive we will split up into small groups,” which part(s) is/are prepositional phrase(s)?

• A. “as a class”
• B. “when we arrive”
• C. “into small groups”
• D. (a) and (c) but not (b)

Correct answer: D

Rationale: The prepositional phrases in the sentence are 'as a class' and 'into small groups,' making choices (a) and (c) correct. The phrase 'when we arrive' is not a prepositional phrase but rather a subordinate clause indicating a time. Prepositional phrases typically begin with a preposition (as, into) and end with a noun, pronoun, gerund, or clause. Therefore, the correct answer is option D, as it correctly identifies the prepositional phrases in the sentence.

5. According to Newton's third law of motion, if you push against a wall with a certain force, the wall will push back with:

• A. A smaller force
• B. An equal force
• C. A greater force
• D. No force at all

Correct answer: B

Rationale: According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When you push against a wall with a certain force, the wall will push back on you with an equal force in the opposite direction. Choice A is incorrect because the wall exerts an equal force back. Choice C is incorrect as it suggests a greater force, which goes against Newton's third law. Choice D is incorrect as the wall does exert a force back in response to your push.
