1. What property of matter determines its resistance to changes in shape or size?

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

Correct answer: A

Rationale: The correct answer is 'Solid.' Solids have a definite shape and volume, providing them with a strong resistance to changes in shape or size. Liquids and gases do not have a definite shape, making them prone to changing shape or size easily. Plasmas, on the other hand, are ionized gases with high energy levels and lack a definite shape or volume, which does not contribute to resistance against changes in shape or size. Therefore, the properties of solids make them best suited for resisting changes in shape or size compared to liquids, gases, and plasmas.

2. Which of the following sentences best represents style and clarity of expression?

• A. Without adequate preparation, the test was likely to be a failure for Zara.
• B. The test was likely to be a failure for Zara without adequate preparation.
• C. Without adequate preparation, Zara expected to fail the test.
• D. Zara expected to fail the test without adequate preparation.

Correct answer: C

Rationale: Choice C, 'Without adequate preparation, Zara expected to fail the test,' is the best option as it maintains clarity and conciseness. The subject 'Zara' is directly linked to the action 'expected to fail the test' with the cause 'Without adequate preparation' clearly stated at the beginning. This structure enhances the flow of the sentence and makes it easier to understand. Choices A, B, and D are less clear as they place the cause and effect in less optimal positions, resulting in a less effective and concise expression of the idea.

3. What is the domain for the function y = 1/x?

• A. All real numbers except 0
• B. x > 0
• C. x = 0
• D. x = 1

Correct answer: A

Rationale: The domain of a function consists of all possible input values that produce a valid output. In the case of y = 1/x, the function is undefined when x = 0 because division by zero is not defined in mathematics. Therefore, the correct domain for y = 1/x is all real numbers except 0 (Choice A). Choice B, x > 0, is incorrect because it excludes the value x = 0. Choice C, x = 0, is also incorrect as x = 0 is not a valid part of the domain due to the function being undefined at this point. Choice D, x = 1, is unrelated to the domain of the function and does not represent the set of valid input values for y = 1/x.

4. After an unexpected rearrangement of their schedules, Thomas and his sister realize that they will have to squeeze in the film after 10 p.m. Given this new information, which cinema is the best option?

• A. Twin Theatres
• B. Reveler Cinema
• C. Big Screen 14
• D. Best Seat in The House

Correct answer: B

Rationale: Since Thomas and his sister have to squeeze in the film after 10 p.m., they need to watch the film later in the evening. Among the options, Reveler Cinema offers showtimes after 10 p.m. with a showing at 7:15 p.m., making it the best choice. Twin Theatres, Big Screen 14, and Best Seat in The House do not have showtimes after 10 p.m., making Reveler Cinema the most suitable option for the siblings to catch a film at that time.

5. A patient requires a 20% decrease in medication dosage. Their current dosage is 400 mg. What will their dosage be after the decrease?

• A. 60 mg
• B. 80 mg
• C. 120 mg
• D. 320 mg

Correct answer: B

Rationale: To calculate a 20% decrease of 400 mg, you multiply 400 mg by 0.20 to get 80 mg. Subtracting 80 mg from the current dosage of 400 mg results in a new dosage of 320 mg. Choice A is incorrect because it miscalculates the decrease. Choice C is incorrect as it represents a 20% increase instead of a decrease. Choice D is incorrect as it represents the initial dosage, not the reduced dosage.
