1. In hydraulic systems, Pascal's principle states that a pressure change applied to a confined incompressible fluid is:

• A. Amplified but loses energy
• B. Transmitted undiminished throughout the fluid
• C. Limited by the container size
• D. Dependent on the fluid type

Correct answer: B

Rationale: Pascal's principle states that when a pressure change is applied to a confined incompressible fluid, the resulting pressure change is transmitted undiminished throughout the fluid. This means that the pressure change will be the same at every point in the fluid, regardless of the container size or the type of fluid used. Therefore, choice B is the correct answer. Choices A, C, and D are incorrect because Pascal's principle specifically emphasizes the transmission of pressure without amplification, limitation by container size, or dependence on the fluid type.

2. Which vitamin is necessary for the formation of collagen?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: B

Rationale: Vitamin C is essential for the synthesis of collagen, a crucial protein that plays a significant role in maintaining the structural integrity of skin, blood vessels, and bones. Collagen is responsible for the strength, elasticity, and firmness of these tissues. Without sufficient vitamin C, the body cannot form collagen properly, leading to various health issues like scurvy, impaired wound healing, and fragile blood vessels. Choices A, C, and D are incorrect. Vitamin A plays a role in vision, immune function, and skin health. Vitamin D is crucial for bone health and immune function, while Vitamin E is an antioxidant that helps protect cells from damage.

3. The hospital accepts a certain quota of 'indigent' patients.

• A. Uninjured
• B. Apathetic
• C. Resentful
• D. Impoverished

Correct answer: D

Rationale: The word 'indigent' refers to people who are poor or impoverished, lacking financial resources. Therefore, the correct choice is D, 'Impoverished.' Choices A, B, and C are incorrect because they do not accurately reflect the meaning of 'indigent.' Choice A, 'Uninjured,' is unrelated to financial status. Choice B, 'Apathetic,' means showing no interest or concern, which is irrelevant. Choice C, 'Resentful,' means feeling bitterness or indignation, which is also unrelated to poverty.

4. What is the absolute value of -7?

• A. 49
• B. 17
• C. 7
• D. 14

Correct answer: C

Rationale: The absolute value of a number is its distance from zero on the number line, regardless of its sign. In this case, the absolute value of -7 is 7 because it is 7 units away from zero in the negative direction. Therefore, the absolute value of -7 is 7. Choice A (49) is incorrect as it is the square of -7, not the absolute value. Choice B (17) and Choice D (14) are incorrect values and do not represent the absolute value of -7.

5. What does 'Contour' mean?

• A. Flat area
• B. Shape or outline of something
• C. Volume of a structure
• D. Height of a structure

Correct answer: B

Rationale: The term 'Contour' specifically refers to the shape or outline of something. In art and geography, contours are used to represent the outline or shape of an object or landform, making choice B the correct definition. Choice A, 'Flat area,' is incorrect as it does not capture the essence of contour which is about the shape or outline. Choice C, 'Volume of a structure,' is unrelated to the concept of contour. Choice D, 'Height of a structure,' is also incorrect as contour is more about the shape and not the height of an object.
