1. 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.

2. Which of the following is an end product of cellular respiration?

• A. Oxygen
• B. ATP energy
• C. Carbon dioxide
• D. Water

Correct answer: B

Rationale: The correct answer is B: ATP energy. During cellular respiration, glucose is broken down to produce ATP, which is the primary energy currency of cells. While oxygen is required for cellular respiration to occur, it is not an end product but rather a reactant. Carbon dioxide and water are byproducts of cellular respiration, alongside ATP. Therefore, options A, C, and D are incorrect as they are not end products of cellular respiration.

3. Which of the following vessels is responsible for transporting blood from the heart to the lungs?

• A. Pulmonary vein
• B. Pulmonary artery
• C. Aorta
• D. Superior vena cava

Correct answer: B

Rationale: The correct answer is B, Pulmonary artery. The pulmonary artery carries deoxygenated blood from the heart's right ventricle to the lungs for oxygenation. This blood then undergoes the gas exchange process in the lungs, where carbon dioxide is removed, and oxygen is absorbed. The pulmonary vein, identified in choice A, carries oxygenated blood from the lungs back to the heart, which is the opposite direction of the blood flow specified in the question. Choice C, Aorta, is responsible for carrying oxygen-rich blood from the heart's left ventricle to the rest of the body, not to the lungs. Choice D, Superior vena cava, returns deoxygenated blood from the upper body to the heart's right atrium, but it does not transport blood specifically to the lungs as requested in the question.

4. The shimmering image of water seen on a hot road is a well-known example of:

• A. Reflection
• B. Refraction
• C. Interference
• D. Polarization

Correct answer: B

Rationale: The shimmering image of water seen on a hot road is a result of refraction, not reflection. Refraction is the bending of light as it passes from one medium to another of different optical density. In this case, the hot air just above the road has a different density than the cooler air above it, causing light to bend and create the illusion of water on the road. Refraction is the most suitable explanation for this phenomenon, as it involves the bending of light rays due to the change in the medium's optical density, producing the visual effect observed on the hot road. Reflection, interference, and polarization do not involve the bending of light due to changes in optical density and are not applicable to the scenario described on the hot road.

5. The area known as the Bermuda Triangle has become such a part of popular culture that it can be difficult to separate fact from fiction. Which of the following describes this type of writing?

• A. Narrative
• B. Persuasive
• C. Expository
• D. Technical

Correct answer: C

Rationale: Expository writing is used to explain or inform, as seen in the factual account of the Bermuda Triangle. The passage provides information to explain the phenomenon of the Bermuda Triangle, presenting facts and details without attempting to persuade or tell a story (narrative) or focusing on technical details. While the Bermuda Triangle has inspired many stories and theories, the passage aims to inform rather than persuade or delve into technical aspects.
