1. What is the primary function of the small intestine?

• A. To absorb water
• B. To absorb nutrients
• C. To store waste
• D. To produce enzymes

Correct answer: B

Rationale: The correct answer is B: "To absorb nutrients." The small intestine's primary function is to absorb nutrients from digested food. It plays a crucial role in the digestion and absorption of nutrients such as proteins, carbohydrates, fats, vitamins, and minerals, which are essential for the body's functions and energy production. Choice A, "To absorb water," is incorrect because the absorption of water primarily occurs in the large intestine. Choice C, "To store waste," is incorrect as waste is stored in the large intestine before elimination. Choice D, "To produce enzymes," is incorrect because while the small intestine does receive enzymes from other organs to aid in digestion, its primary role is not enzyme production.

2. What is a prime number?

• A. A number divisible by only 1 and itself
• B. A number divisible by 2 and 3
• C. A number divisible by any number
• D. A number with exactly three factors

Correct answer: A

Rationale: The correct answer is A: 'A number divisible by only 1 and itself.' A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. This definition aligns with choice A. Choice B is incorrect because not all prime numbers are divisible by 2 and 3. Choice C is incorrect as prime numbers are not divisible by any number other than 1 and themselves. Choice D is incorrect because a prime number has exactly two factors, 1 and itself, not three factors.

3. Why is the lining of the stomach covered with rugae?

• A. Rugae increase the output of gastric juices.
• B. Rugae increase the surface area of the stomach.
• C. Rugae increase the permeability of the stomach walls.
• D. Rugae increase the types of nutrients that can diffuse.

Correct answer: B

Rationale: Rugae are folds in the stomach lining that increase its surface area. This increased surface area allows for more efficient digestion and absorption of nutrients in the stomach. Choice A is incorrect because rugae do not directly affect the output of gastric juices. Choice C is incorrect because rugae do not impact the permeability of the stomach walls. Choice D is incorrect because rugae do not influence the types of nutrients that can diffuse.

4. What is the underlined portion of the sentence an example of? New students should report to the student center.

• A. Dependent clause
• B. Adverbial phrase
• C. Adjective clause
• D. Noun phrase

Correct answer: D

Rationale: The correct answer is D, 'Noun phrase.' In the sentence 'New students should report to the student center,' the underlined portion 'new students' is a noun phrase functioning as the subject of the sentence. A dependent clause is a group of words with a subject and verb that does not express a complete thought, which is not the case here. An adverbial phrase modifies a verb, adjective, or adverb and typically answers questions like 'how,' 'when,' 'where,' or 'why,' which is not applicable in this context. An adjective clause is a group of words that describe a noun, but 'new students' in the sentence is not serving as a descriptive element of another noun; instead, it is the main subject.

5. Identify the adjective in the following sentence: The colorful sunset painted the sky with vibrant hues.

• A. sunset
• B. with
• C. colorful
• D. painted

Correct answer: C

Rationale: The correct answer is 'C - colorful.' Adjectives are words that describe or modify nouns or pronouns. In this sentence, 'colorful' describes the noun 'sunset,' making it the adjective in the sentence. Choice A, 'sunset,' is a noun, not an adjective. Choice B, 'with,' is a preposition. Choice D, 'painted,' is a verb, not an adjective. Therefore, the correct answer is 'C - colorful.'
