1. What property of a substance refers to its ability to be drawn into thin wires?

• A. Conductivity
• B. Ductility
• C. Viscosity
• D. Malleability

Correct answer: B

Rationale: Ductility is the property of a substance that allows it to be drawn into thin wires without breaking. Conductivity refers to the ability of a substance to conduct electricity or heat, not to be drawn into wires. Viscosity is the measure of a fluid's resistance to flow, not related to the ability to be drawn into wires. Malleability is the property of a substance that allows it to be hammered or rolled into thin sheets, not specifically related to being drawn into wires. Therefore, the correct property for the ability to be drawn into thin wires is ductility.

2. Which of the following most accurately describes how the argument proceeds?

• A. The argument proceeds by stating a conclusion, then providing supporting evidence.
• B. The argument proceeds by stating several facts and drawing a conclusion.
• C. The argument proceeds by offering a premise, then refuting it.
• D. The argument proceeds by making a comparison between two subjects.

Correct answer: A

Rationale: The correct answer is A. The argument in the text proceeds by stating a conclusion ('Dwight is the best employee') and then providing supporting evidence ('The top salesman is always the best employee'). This aligns with choice A, where the argument is structured by stating a conclusion first and then offering supporting evidence. Choices B, C, and D are incorrect because the argument in the text does not simply present facts and draw a conclusion, offer a premise and then refute it, or make a comparison between two subjects.

3. As a car accelerates from rest, what happens to its kinetic energy and the work done on it?

• A. Both kinetic energy and work done increase.
• B. Kinetic energy increases, but work done remains constant.
• C. Work done increases, but kinetic energy remains constant.
• D. Both kinetic energy and work done remain constant.

Correct answer: A

Rationale: When a car accelerates from rest, its speed and kinetic energy increase. The work done on the car is what increases its kinetic energy, so both kinetic energy and work done increase simultaneously. Option A is correct because acceleration results in an increase in both kinetic energy and the work done on the car. Option B is incorrect because work done is required to increase kinetic energy during acceleration. Option C is incorrect as work done is directly related to the change in kinetic energy. Option D is incorrect as both kinetic energy and work done increase when the car accelerates.

4. Which of the following is the correct tense used in the bold part in this sentence? My grandpa WILL BE WRITING a memoir...

• A. Future progressive
• B. Past perfect
• C. Future simple
• D. Present perfective

Correct answer: A

Rationale: The correct answer is A, Future progressive. 'Will be writing' indicates an ongoing action that will occur in the future, which is the future progressive tense. Choice B, Past perfect, is incorrect as it refers to an action completed before a specified time in the past. Choice C, Future simple, is incorrect as it refers to a simple future action without indicating ongoing progress. Choice D, Present perfective, is incorrect as it does not match the tense used in the sentence.

5. Which type of wave requires a medium to travel through?

• A. Electromagnetic waves
• B. Mechanical waves
• C. Sound waves
• D. Both A and C

Correct answer: B

Rationale: Mechanical waves, unlike electromagnetic waves, require a medium (such as air, water, or solids) to propagate. Sound waves are a specific type of mechanical wave that necessitates a medium, like air or water, for transmission. Electromagnetic waves, on the other hand, can travel through a vacuum as they do not rely on a medium for propagation. Choice A (Electromagnetic waves) is incorrect since they do not require a medium to travel. Choice C (Sound waves) is partially correct in that it is a type of mechanical wave that needs a medium but is not the only type. Choice D (Both A and C) is incorrect because electromagnetic waves do not require a medium, only mechanical waves like sound waves do.
