1. If y = 4 and x = 3, solve y x³

• A. -108
• B. 108
• C. 27
• D. 4

Correct answer: B

Rationale: With y = 4 and x = 3, the expression is y × x³. Substituting the values, we get 4 × 3³ = 4 × 27 = 108. Therefore, the correct answer is 108. Option A (-108) is incorrect because the negative sign is not part of the result. Option C (27) is incorrect as it only represents x³ without considering the value of y. Option D (4) is incorrect as it represents the initial value of y, not the result of y × x³.

2. Select the phrase or clause that is misplaced in the following sentence. With torn pages, I returned the book I’d just bought to the store.

• A. With torn pages
• B. I returned the book
• C. I’d just bought
• D. to the store

Correct answer: A

Rationale: The phrase 'With torn pages' is misplaced in the sentence because it disrupts the flow of the sentence. Placing it at the beginning creates an awkward structure. It would be clearer to present the main action first before adding the detail about the torn pages. In this case, rearranging the sentence to 'I returned the book I’d just bought to the store with torn pages' would improve the sentence's coherence and readability. Choices B, C, and D are not misplaced in the sentence as they follow a logical order of action and description.

3. The voice box may be called the ______

• A. Pharynx
• B. Larynx
• C. Trachea
• D. Esophagus

Correct answer: B

Rationale: The correct term for the voice box is the larynx. The pharynx is part of the throat involved in swallowing and breathing but not the voice production. The trachea is the windpipe responsible for air passage, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, in this context, the larynx is the most appropriate term.

4. What time is 6:30 A.M. in military time?

• A. 0630
• B. 6030
• C. 1503
• D. 1530

Correct answer: A

Rationale: Military time uses a 24-hour clock format where the hours range from 00 to 23. In this format, 6:30 A.M. is expressed as 0630. Choice B (6030) and Choice C (1503) are incorrect as they do not follow the 24-hour clock format. Choice D (1530) represents 3:30 P.M., not 6:30 A.M.

5. Ocean waves may tear sponges into pieces, each of which may grow into a new sponge. What is this form of reproduction called?

• A. Budding
• B. Vegetative propagation
• C. Binary fission
• D. Fragmentation

Correct answer: D

Rationale: Fragmentation is the form of asexual reproduction where an organism breaks into fragments, and each fragment can grow into a new individual. In the case of sponges being torn into pieces by ocean waves, each piece has the potential to develop into a new sponge, making fragmentation the correct answer in this scenario. Budding is a form of asexual reproduction where a new organism develops as an outgrowth from the parent organism. Vegetative propagation involves the growth of new individuals from plant parts like stems or roots. Binary fission is a method of reproduction seen in some single-celled organisms where one cell divides into two identical cells.
