1. Which nutrients are important for bone health?

• A. Vitamin D
• B. Calcium and phosphorus
• C. Iron and zinc
• D. Magnesium and sodium

Correct answer: B

Rationale: Calcium and phosphorus are crucial nutrients for bone health as they are essential minerals required for bone strength, density, and various body functions. Adequate intake of calcium and phosphorus through the diet is important for maintaining healthy bones and preventing conditions like osteoporosis. Vitamin D helps with calcium absorption, but it is not the main nutrient responsible for bone health. Iron and zinc are important for other bodily functions, not specifically bone health. Magnesium and sodium, while important for overall health, are not as directly linked to bone health as calcium and phosphorus.

2. What is the value of x in the ratio and proportion 0.1:10=x:400?

• A. 5
• B. 4
• C. 50
• D. 25

Correct answer: B

Rationale: To solve the proportion 0.1:10=x:400, first, simplify the left side to 1:100. Then, set up the proportion as 1:100=x:400. Cross multiply to get x = 4. Therefore, the correct answer is B. Choice A (5) is incorrect because it does not match the calculated value of x. Choice C (50) is incorrect as it is not the result of solving the proportion provided. Choice D (25) is incorrect as it does not align with the correct calculation of x.

3. Multiply: 4/9 × 1 4/5 × 2/5.

• A. 8/25
• B. 1 & 10/19
• C. 7/16
• D. 32/45

Correct answer: A

Rationale: To multiply the fractions, convert the mixed numbers to improper fractions: 1 4/5 = 9/5. Then, multiply the fractions: (4/9) × (9/5) × (2/5) = 8/25. The correct answer is A. Choice B is incorrect as it does not match the result of the multiplication. Choice C is incorrect as it is not the result of multiplying the fractions. Choice D is incorrect as it is not the result of the given multiplication.

4. The mail carrier's job is to put the _____ in every mailbox on the block.

• A. letter
• B. envelope
• C. package
• D. documents

Correct answer: B

Rationale: The correct answer is B: 'envelope.' The mail carrier typically delivers envelopes containing mail to every mailbox on the block. Envelopes are commonly used to protect and contain letters, making them the most suitable choice in this context. Choices A, C, and D are incorrect because while the mail carrier may deliver letters, packages, or documents, the most common item placed in mailboxes is an envelope containing mail.

5. A sore with disintegration of tissue might be called an ___________.

• A. allergy
• B. erythema
• C. alopecia
• D. ulcer

Correct answer: D

Rationale: A sore with disintegration of tissue is typically referred to as an ulcer. Ulcers are open sores or wounds that can develop on the skin's surface or within the body. They can vary in size and depth and are commonly associated with conditions such as pressure ulcers, peptic ulcers, and venous ulcers. Ulcers result from the breakdown of tissue, leading to a loss of the skin or mucous membrane in that area. Choices A, B, and C are incorrect. Allergy refers to a hypersensitivity reaction, erythema is redness of the skin, and alopecia is hair loss. These conditions do not specifically involve the disintegration of tissue as seen in an ulcer.
