1. The word 'massive' in line 4 is closest in meaning to?

• A. Dense
• B. Impressive
• C. Huge
• D. Unavoidable

Correct answer: C

Rationale: In the context of the passage, 'massive' is used to describe the size of the collision that formed the Moon, indicating something very large or huge. While 'dense' means closely compacted, 'impressive' means evoking admiration, 'huge' is the closest synonym to 'massive' in this context. 'Unavoidable' does not convey the same meaning as 'massive' in this sentence, making it incorrect.

2. What is matter that has a definite shape and volume?

• A. Liquid
• B. Solid
• C. Gas
• D. Plasma

Correct answer: B

Rationale: Matter that has a definite shape and volume is referred to as a solid. Solids maintain their shape and volume under normal conditions, unlike liquids that have a definite volume but take the shape of their container, gases that have neither a definite shape nor volume, and plasma which is a state of matter with no definite shape or volume and consists of charged particles.

3. What is the kinetic energy of a 500-kg wagon moving at 10 m/s?

• A. 50 J
• B. 250 J
• C. 2.5 × 10^4 J
• D. 5.0 × 10^5 J

Correct answer: C

Rationale: The formula for calculating kinetic energy is KE = 0.5 × mass × velocity². Given the mass of the wagon is 500 kg and the velocity is 10 m/s, we can substitute these values into the formula: KE = 0.5 × 500 kg × (10 m/s)² = 0.5 × 500 kg × 100 m²/s² = 25,000 J or 2.5 × 10⁴ J. Therefore, the kinetic energy of the 500-kg wagon moving at 10 m/s is 2.5 × 10⁴ J. Choice A (50 J) is incorrect because it is too low; Choice B (250 J) is incorrect as it does not match the correct calculation; Choice D (5.0 × 10^5 J) is incorrect as it is too high. The correct answer is C (2.5 × 10^4 J).

4. Choose the meaning of the word vent in the following sentence: 'A tube is used to vent the gases to the outside.'

• A. Block
• B. Trade
• C. Emit
• D. Inhale

Correct answer: C

Rationale: In this sentence, the word 'vent' means to allow the gases to escape or be emitted to the outside. 'Block' is incorrect because it means to obstruct or close off. 'Trade' is incorrect as it refers to the exchange of goods or services. 'Inhale' is incorrect as it means to breathe in, which is the opposite of venting gases out.

5. Which of the following words fits best in the following sentence? ___________ the emergency room was not busy last night, the head nurse still did not let anyone end her shift early.

• A. Because
• B. Provided that
• C. As if
• D. Although

Correct answer: D

Rationale: The word 'although' is the best fit in the sentence because it indicates a contrast between the fact that the emergency room was not busy last night and the head nurse's decision not to let anyone end her shift early. 'Although' sets up a contrast by acknowledging the first part of the sentence while introducing the surprising or unexpected information that follows. Choices A, B, and C do not provide the appropriate contrast needed in this context. 'Because' implies causation, 'Provided that' implies a condition for something to happen, and 'As if' implies a comparison rather than a contrast.
