1. In the sentence 'Singing is my favorite activity,' how does 'Singing' function in terms of parts of speech?

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

Correct answer: B

Rationale: In the sentence provided, 'Singing' is a gerund, which is a verb form ending in -ing that functions as a noun. It represents the action of singing, but in this context, it acts as the subject of the sentence. Therefore, 'Noun' is the correct answer. 'Verb' (choice A) is incorrect because while gerunds are verb forms, in this sentence, 'Singing' is not acting as a verb. 'Adjective' (choice C) is incorrect as it describes a noun, which is not the case here. 'Pronoun' (choice D) is also incorrect as 'Singing' does not replace a noun in this sentence.

2. What is the equivalent of 500 milliliters in liters?

• A. 0.05 liters
• B. 0.5 liters
• C. 5 liters
• D. 50 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 500 milliliters divided by 1000 equals 0.5 liters. Choice A (0.05 liters) is incorrect because it represents 50 milliliters, not 500 milliliters. Choice C (5 liters) and Choice D (50 liters) are both incorrect as they are higher values and do not accurately represent the conversion of 500 milliliters to liters.

3. Where does most of the chemical digestion and absorption of nutrients occur?

• A. Mouth
• B. Stomach
• C. Small intestine
• D. Large intestine

Correct answer: C

Rationale: The small intestine is the primary site for both chemical digestion and absorption of nutrients in the digestive system. The lining of the small intestine is equipped with villi and microvilli, which significantly increase the surface area available for absorption. Enzymes from the pancreas and bile from the liver play crucial roles in further breaking down food into absorbable molecules that can pass through the intestinal wall into the bloodstream. While the stomach assists in mechanical breakdown and initial protein digestion, it is not the main site of nutrient absorption. The large intestine, on the other hand, mainly absorbs water and electrolytes from undigested food particles. The mouth aids in initial mechanical breakdown and some carbohydrate digestion, but the majority of nutrient absorption occurs in the small intestine, making it the correct answer.

4. What is the central idea conveyed in the passage?

• A. David Foster Wallace's Infinite Jest is the holy grail of modern literature.
• B. Infinite Jest is a page-turner.
• C. David Foster Wallace wrote Infinite Jest.
• D. Infinite Jest is a modern classic for good reason and everybody should read it.

Correct answer: D

Rationale: The passage describes Infinite Jest as a modern classic that holds significant value, indicating that it is highly recommended for everyone to read it. Choice A focuses solely on the praise of the book without emphasizing the recommendation to read it. Choice B, mentioning it as a page-turner, does not capture the essence of it being a modern classic that everyone should read. Choice C is a factual statement about the authorship but does not encompass the main point that the book is a modern classic that deserves to be read by all.

5. What happens to the wavelength of a wave when its frequency increases while the speed remains constant?

• A. Wavelength increases
• B. Wavelength decreases
• C. Wavelength remains the same
• D. Wavelength becomes zero

Correct answer: B

Rationale: When the speed of a wave is constant and the frequency increases, the wavelength must decrease to keep the speed constant. The speed of a wave is determined by the product of frequency and wavelength (speed = frequency x wavelength). If the frequency increases while the speed remains constant, the wavelength has to decrease proportionally to maintain the speed unchanged. Therefore, as the frequency increases, the wavelength decreases to ensure that the speed of the wave remains constant. Choice A is incorrect because as frequency increases, wavelength decreases. Choice C is incorrect as the wavelength cannot remain the same when frequency increases while speed is constant. Choice D is incorrect as the wavelength cannot become zero under these conditions.
