1. Which mineral is crucial for bone strength and is stored in bones and teeth?

• A. Calcium
• B. Iron
• C. Magnesium
• D. Potassium

Correct answer: A

Rationale: Calcium is crucial for bone strength as it is a major mineral stored in bones and teeth. It plays a vital role in maintaining bone density and strength, making it essential for overall bone health. Calcium is essential for various physiological functions, including muscle contraction, nerve transmission, and blood clotting. Inadequate calcium intake can lead to conditions like osteoporosis, where bones become weak and brittle. Iron (Choice B) is important for transporting oxygen in the blood, but it is not stored in bones and does not play a significant role in bone strength. Magnesium (Choice C) is essential for bone health, but it is not primarily stored in bones and teeth. Potassium (Choice D) is crucial for various physiological functions, such as fluid balance and muscle function, but it is not a major mineral stored in bones and teeth for bone strength.

2. Which of the following best describes the relationship in this set of data?

• A. High positive correlation
• B. Low positive correlation
• C. Low negative correlation
• D. No correlation

Correct answer: B

Rationale: The correct answer is 'B: Low positive correlation.' In a low positive correlation, the variables tend to increase together, but the relationship is not strong. This description fits the data set provided. Choice A, 'High positive correlation,' is incorrect because the correlation is not strong. Choice C, 'Low negative correlation,' is incorrect as the variables are not decreasing together. Choice D, 'No correlation,' is incorrect because there is a relationship between the variables, albeit weak.

3. The beautiful flowers brightened the room. Which word is the adverb form of the adjective 'beautiful'?

• A. beautiful
• B. beautifully
• C. beautification
• D. beautify

Correct answer: B

Rationale: In the sentence, 'beautiful' is used as an adjective to describe the flowers. To transform the adjective 'beautiful' into an adverb, you add '-ly,' resulting in 'beautifully.' Adverbs modify verbs, adjectives, or other adverbs, offering more details on how an action is performed. Choice A ('beautiful') is the original adjective form and not the adverb form. Choice C ('beautification') is a noun, not an adverb. Choice D ('beautify') is a verb, not an adverb.

4. Which of the following describes the type of writing used in the passage?

• A. narrative
• B. persuasive
• C. expository
• D. technical

Correct answer: C

Rationale: The type of writing used in the passage is expository. Expository writing aims to provide information, explain concepts or ideas, and present factual details without trying to persuade or tell a story. In the passage, the text focuses on providing factual information about 'The Five,' their backgrounds, and their influence on classical music without any persuasive elements or narrative storytelling. The passage educates and informs the reader about the topic, which aligns with the characteristics of expository writing. Therefore, 'expository' is the correct description. Choice A (narrative) is incorrect as the passage does not tell a story but rather presents factual information. Choice B (persuasive) is incorrect because there is no attempt to persuade the reader in the passage. Choice D (technical) is also incorrect as the passage does not involve technical instructions or specialized technical details, but rather general information about the subject matter.

5. What is the function of the Golgi apparatus?

• A. Breaking down and recycling cellular waste
• B. Packaging and transporting proteins and lipids
• C. Generating energy through cellular respiration
• D. Translating DNA into proteins

Correct answer: B

Rationale: The Golgi apparatus plays a crucial role in the cell by packaging and modifying proteins and lipids synthesized by the endoplasmic reticulum. These proteins and lipids are then transported to their final destinations within the cell or outside of it. The Golgi apparatus does not break down and recycle cellular waste, generate energy through cellular respiration, or translate DNA into proteins. Its primary function is related to processing and sorting molecules for cellular use.
