1. What is the main component of blood plasma?

• A. Proteins
• B. Water
• C. Red Blood Cells
• D. Platelets

Correct answer: B

Rationale: The correct answer is B: Water. Blood plasma is composed mostly of water, which acts as a solvent for various nutrients and substances. Choices A, C, and D are incorrect. Proteins are indeed present in blood plasma but are not the main component. Red blood cells and platelets are cellular components of blood, not the main component of blood plasma.

2. Which word is not used correctly in the context of the following sentence? Does your grimace infer that you loathed the performance?

• A. grimace
• B. infer
• C. loathed
• D. performance

Correct answer: B

Rationale: The word 'infer' is used incorrectly in the sentence. 'Infer' means to deduce or conclude something based on evidence and reasoning, while in the sentence, the speaker is actually asking if the grimace suggests that the person hated the performance. The correct word that should be used in this context is 'imply' or 'suggest.' 'Grimace' (choice A), 'loathed' (choice C), and 'performance' (choice D) are all used appropriately in the sentence.

4. Which vitamin is essential for bone health?

• A. Vitamin A
• B. Vitamin D
• C. Vitamin C
• D. Vitamin K

Correct answer: B

Rationale: Vitamin D is the correct answer. It is essential for bone health as it helps in the absorption of calcium, a crucial mineral for maintaining strong and healthy bones. Adequate levels of Vitamin D are necessary to prevent conditions like osteoporosis and ensure optimal bone development and strength. Choice A, Vitamin A, is important for vision and immune function, but it is not directly related to bone health. Choice C, Vitamin C, is essential for collagen synthesis and immune function, but it is not primarily responsible for bone health. Choice D, Vitamin K, plays a role in blood clotting and bone metabolism, but Vitamin D has a more direct impact on bone health through its role in calcium absorption.

5. What is the meaning of the word duration as used in the last paragraph?

• A. Basis
• B. Extent
• C. Cure
• D. Solidity

Correct answer: B

Rationale: The word "duration" in the context of sleep refers to the length of time that children should sleep. It suggests a focus on the amount of sleep necessary for healthy development, making option B the correct choice as it aligns with the emphasis on recommended sleep hours for children.
