1. What is the function of ribosomes?

• A. Packaging and transporting proteins
• B. Storing genetic material
• C. Controlling cell division
• D. Synthesizing proteins

Correct answer: D

Rationale: The correct answer is D: Synthesizing proteins. Ribosomes are cellular organelles responsible for protein synthesis. They read the messenger RNA (mRNA) and utilize the information to assemble amino acids into proteins through a process known as translation. Choice A, packaging and transporting proteins, is incorrect as this function is typically performed by the Golgi apparatus and vesicles. Choice B, storing genetic material, is incorrect as genetic material is usually stored in the nucleus in the form of DNA. Choice C, controlling cell division, is incorrect as this function is primarily regulated by the cell cycle checkpoints and specific proteins involved in cell cycle regulation.

2. Which of the following is the largest organ in the human body?

• A. Liver
• B. Brain
• C. Heart
• D. Skin

Correct answer: D

Rationale: The skin is the largest organ in the human body. It covers the entire body, serving as a protective barrier against pathogens, UV radiation, and physical damage. Additionally, the skin plays a crucial role in regulating body temperature and synthesizing vitamin D when exposed to sunlight. Choices A, B, and C are incorrect. The liver is the largest internal organ, the brain is the control center of the body, and the heart is a vital organ responsible for pumping blood throughout the body. However, none of these organs are the largest in terms of surface area or overall size.

3. Which sentence correctly answers the question: What were you doing when the thunderstorm started?

• A. I mowed the lawn.
• B. I am mowing the lawn.
• C. I was mowing the lawn.
• D. I have mowed the lawn.

Correct answer: C

Rationale: The correct answer is 'C: I was mowing the lawn.' This sentence correctly uses the past continuous tense to indicate an action that was in progress at a specific time in the past when the thunderstorm started. Choice A 'I mowed the lawn' is in simple past tense, not past continuous, and does not convey the ongoing nature of the action. Choice B 'I am mowing the lawn' is in present continuous tense, not past continuous, and does not match the past timeframe. Choice D 'I have mowed the lawn' is in present perfect tense, not past continuous, and does not convey the ongoing action at a specific past time.

4. How does the mass of an object affect its inertia?

• A. Mass has no impact on inertia
• B. Higher mass increases inertia
• C. Higher mass decreases inertia
• D. Mass influences gravitational force, not inertia

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This concept aligns with Newton's first law of motion, which states that an object at rest will remain at rest, and an object in motion will continue in motion with the same speed and direction unless acted upon by an external force. Therefore, higher mass increases inertia, making it more difficult to alter the object's state of motion. Choice A is incorrect as mass does impact inertia. Choice C is incorrect as higher mass actually increases inertia, not decreases it. Choice D is incorrect as while mass does affect gravitational force, it also directly impacts inertia.

5. What is the author’s conclusion about the house on Pine Street?

• A. The house did not have enough bedrooms.
• B. The house did not have a big enough yard.
• C. The house was not in the right neighborhood.
• D. The house was too expensive.

Correct answer: D

Rationale: The author's conclusion about the house on Pine Street is that it was too expensive. This can be inferred from the description provided in the text, where it is mentioned that although the house had enough space inside, it didn't have a big enough yard for their dogs, and the cost of the house was well above their price range. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not align with the evidence from the text, which clearly points to the cost being the main issue with the house on Pine Street.
