1. What property of a wave represents the distance between two successive identical points on a wave?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Period

Correct answer: A

Rationale: The wavelength of a wave represents the distance between two successive identical points on a wave, such as two crests or two troughs. It is typically measured in meters and is a fundamental characteristic of a wave, influencing its properties and behavior. Wavelength is crucial in wave physics, affecting phenomena like interference, diffraction, and the wave's speed in a medium. Amplitude refers to the maximum displacement of a wave from its rest position, frequency is the number of complete oscillations a wave makes in a given time, and period is the time it takes for a wave to complete one full cycle. These properties are different from wavelength and serve distinct purposes in describing waves.

2. In the following sentence, which part of speech does the word 'capacity' function as?

• A. Verb
• B. Noun
• C. Adverb
• D. Pronoun

Correct answer: B

Rationale: In the sentence, 'capacity' is used to refer to the maximum amount that something can contain or produce, making it a noun. It is not functioning as a verb (choice A), as it is not describing an action. It is not an adverb (choice C) because it is not modifying a verb, adjective, or another adverb. Additionally, it is not a pronoun (choice D) because it is not replacing a noun or noun phrase. Therefore, the correct answer is 'B: Noun.'

3. Why is it not recommended to edit while writing your first draft?

• A. It is considered prewriting.
• B. It wastes effort.
• C. It clouds judgment.
• D. It changes the organization.

Correct answer: B

Rationale: The correct answer is B: 'It wastes effort.' Editing while writing the first draft can be counterproductive as it interrupts the flow of ideas and slows down the writing process. Instead of focusing on perfecting each sentence or paragraph, it is more beneficial to get all ideas down first during the initial drafting phase. Choice A is incorrect as editing is not part of the prewriting stage. Choice C is incorrect because editing may affect the quality of judgment but is not the primary reason to avoid it during the first draft. Choice D is incorrect because changes in organization can be made during the revision stage, not necessarily while writing the initial draft.

4. What is the main function of dietary fiber in the digestive system?

• A. To provide energy
• B. To break down fats
• C. To promote gut bacteria growth
• D. To aid in absorption of nutrients

Correct answer: C

Rationale: Dietary fiber refers to the indigestible portion of plant foods that passes relatively intact through the digestive system. While fiber does not directly provide energy to the body, it plays a crucial role in promoting the growth of beneficial gut bacteria. These bacteria help in the fermentation of fiber, producing short-chain fatty acids that can be used as an energy source by the body. Additionally, fiber aids in regulating bowel movements, maintaining gut health, and supporting overall digestive function. The functions described in the incorrect choices do not align with the primary role of dietary fiber in the digestive system. Choice A is incorrect because fiber itself is not a direct energy source. Choice B is incorrect as fiber does not break down fats. Choice D is incorrect because while fiber affects nutrient absorption indirectly by supporting gut health, its primary role is not to aid in the absorption of nutrients.

5. Out of 9 trips, a person chooses the longest route for 3 of them. What percentage of their trips is the longest route?

• A. 0.25
• B. 0.33
• C. 0.5
• D. 0.75

Correct answer: B

Rationale: To find the percentage of trips where the person chose the longest route, divide the number of longest route trips (3) by the total number of trips (9) and multiply by 100. This gives (3/9) * 100 = 33.33%, which can be rounded to 33%. Therefore, the correct answer is B. Choice A (0.25), C (0.5), and D (0.75) are incorrect because they do not accurately represent the percentage of trips where the longest route was chosen based on the given information.
