1. Which sentence uses parentheses correctly?

• A. The suspect was seen driving a red car (a witness reported).
• B. The movie (released in 2022) received critical acclaim.
• C. The restaurant offers a variety of dishes (including vegetarian options).
• D. All participants (must register by Friday) will receive a free gift.

Correct answer: B

Rationale: The correct use of parentheses is to provide additional non-essential information to the main sentence. In option B, 'released in 2022' is additional detail about the movie but not necessary for the sentence's core meaning. Options A, C, and D could function without parentheses without affecting their essential message, making them incorrect uses of parentheses in this context. Therefore, choice B is the correct answer.

2. DNA has both a 'sense' and 'antisense' strand. What is true about the antisense strand?

• A. It runs 5' to 3'.
• B. It runs 3' to 5'.
• C. It is used in replication.
• D. It is the direction DNA is stored.

Correct answer: B

Rationale: The correct answer is B: 'It runs 3' to 5'. The antisense strand runs in the 3' to 5' direction, complementing the sense strand. Choice A is incorrect as the antisense strand runs in the opposite direction, which is 3' to 5'. Choice C is incorrect because the antisense strand is not directly involved in replication. Choice D is incorrect as the direction DNA is stored is not determined by the antisense strand.

3. When making a dilution, what do you do?

• A. Add more solvent to a concentrated solution
• B. Change the temperature of the solution
• C. Decrease the concentration of a solution
• D. All of the above

Correct answer: C

Rationale: When making a dilution, you decrease the concentration of a solution by adding more solvent to a concentrated solution. This process does not involve changing the temperature of the solution, so option B is incorrect. Option A is also incorrect because you are not adding more solute to the solution during dilution. Therefore, the correct answer is C) Decrease the concentration of a solution. Options A and B are incorrect as dilution involves adding more solvent, not solute, and does not require changing the temperature of the solution.

4. Which property of matter refers to the amount of space occupied by an object and is measured in cubic units?

• A. Mass
• B. Density
• C. Weight
• D. Volume

Correct answer: D

Rationale: Volume is the property of matter that refers to the amount of space occupied by an object. It is measured in cubic units, such as cubic meters or cubic centimeters. Mass, on the other hand, is the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass per unit volume of a substance. In this question, the key concept is the space occupied by an object, which directly relates to volume, making it the correct answer. Choices A, B, and C are incorrect as they do not specifically pertain to the amount of space occupied by an object.

5. Which word correctly completes the sentence: 'He was _____ by the kindness of strangers.'

• A. affected
• B. infected
• C. effected
• D. defected

Correct answer: C

Rationale: The correct answer is 'effected.' In this context, 'effected' means to produce a result or impression, which aligns with the emotional impact of the strangers' kindness. The other choices are incorrect: A) 'affected' might seem plausible, but 'effected' is a better fit as it implies a direct result. B) 'infected' is incorrect as it implies a negative or harmful impact, which is not the intended meaning. D) 'defected' means to abandon allegiance, which is not relevant in the given sentence.
