1. Which sentence is an example of passive voice?

• A. The teacher graded the tests.
• B. The tests were graded by the teacher.
• C. The students took the test.
• D. The test was difficult.

Correct answer: B

Rationale: The correct answer is B: 'The tests were graded by the teacher.' This sentence is an example of passive voice, where the subject receives the action. In passive voice construction, the focus is on the receiver of the action rather than the doer. Choices A, C, and D are not in passive voice. Choice A 'The teacher graded the tests' is in active voice where the subject (teacher) performs the action. Choice C 'The students took the test' is also in active voice with the subject (students) carrying out the action. Choice D 'The test was difficult' is in passive voice but does not exemplify the subject receiving an action performed by an agent, which is a defining characteristic of passive voice.

2. In a research study, a researcher collects data on the number of hours spent studying and the grades students received. Which of the following is the dependent variable?

• A. The number of hours spent studying
• B. The grades students received
• C. The subjects students studied
• D. The number of students in the study

Correct answer: B

Rationale: The correct answer is B: 'The grades students received.' In this scenario, the grades students received are the dependent variable because they are influenced by the number of hours spent studying. The grades are the outcome that is being measured based on the manipulation or observation of the independent variable, which in this case is the number of hours spent studying. Choices A, C, and D are incorrect. The number of hours spent studying is the independent variable being manipulated or observed, the subjects students studied is not directly related to the dependent variable, and the number of students in the study is not the variable being measured or influenced by the independent variable.

3. Which example uses correct punctuation?

• A. "I really can't make it," he answered, "you should probably go without me."
• B. "I really can't make it," he answered. "you should probably go without me."
• C. "I really can't make it," he answered. "You should probably go without me."
• D. "I really can't make it," he answered, "you should probably go without me."

Correct answer: A

Rationale: Choice A uses proper dialogue punctuation. The comma appears inside the closing quotation mark after 'make it,' and 'you' remains lowercase because it continues the same sentence. In Choice B, there is a period instead of a comma after 'answered,' breaking the sentence incorrectly. Choice C incorrectly places the comma outside the quotation mark after 'make it.' Choice D, similar to Choice B, uses a period instead of a comma after 'answered,' leading to incorrect punctuation.

4. Which vitamin is crucial for calcium absorption and synthesized in the skin upon sun exposure?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D is essential for calcium absorption as it helps regulate calcium and phosphorus levels in the body. When the skin is exposed to sunlight, UVB rays convert a compound in the skin to vitamin D. This vitamin is vital for maintaining bone health and ensuring the overall calcium balance in the body. Choices A, B, and D are incorrect. Vitamin A is important for vision and immune function, Vitamin C is essential for collagen synthesis and immune function, and Vitamin E is an antioxidant that helps protect cells from damage by free radicals. However, none of these vitamins are primarily responsible for calcium absorption and synthesized in the skin upon sun exposure.

5. Which of the following best summarizes the central theme of Wilde's play?

• A. The absurdity of the British aristocracy and its social conventions.
• B. The importance of being sincere and honest in personal relationships.
• C. The dual nature of social standing and the conflicts it creates.
• D. The challenges of maintaining personal integrity in a hypocritical society.

Correct answer: A

Rationale: The correct answer is A: 'The absurdity of the British aristocracy and its social conventions.' The central theme of Wilde's play, as revealed through satire, is the critique of the absurdities and trivialities of the British aristocracy. Wilde uses clever dialogue, puns, and irony to expose the superficiality and hypocrisy of the upper classes. While sincerity and honesty in personal relationships are explored in the play, they are not the central theme. Choice C, the dual nature of social standing and resulting conflicts, is a partial theme but not the central one. Choice D, the challenges of maintaining personal integrity in a hypocritical society, touches on a theme present in the play, but it is not as central as the critique of the British aristocracy's absurdities and social conventions.
