1. What does Consistency refer to?

A. Color of a fluid
B. Degree of viscosity, how thick or thin a fluid is
C. Taste of a fluid
D. Smell of a fluid

Correct answer: B

Rationale: Consistency refers to the degree of viscosity of a fluid, indicating how thick or thin it is. Viscosity is the resistance of a fluid to flow, and it determines its consistency. Choices A, color, C, taste, and D, smell, are not related to consistency. Color, taste, and smell are sensory attributes that do not define the physical property of consistency in fluids.

2. What does Depth mean?

A. The thickness of an object
B. Downward measurement from a surface
C. The length of a surface
D. The area between two points

Correct answer: B

Rationale: Depth refers to the distance or downward measurement from a surface. It is not the thickness of an object (Choice A), as thickness is the measure of how thick or thin an object is, not necessarily related to depth. Additionally, it is not the length of a surface (Choice C) because length typically refers to the longest dimension of an object rather than its depth. Finally, it is not the area between two points (Choice D) because area is a measure of the space within a boundary defined by points, while depth specifically refers to the vertical distance below a surface.

3. What does 'Flushed' refer to?

A. Swollen
B. Reddened or ruddy appearance
C. Discolored
D. Pale

Correct answer: B

Rationale: The correct answer is B: 'Reddened or ruddy appearance.' When someone is flushed, it means they have a red or ruddy complexion, often due to embarrassment, anger, or a physical reaction. Choices A, C, and D are incorrect because 'flushed' specifically refers to a red or ruddy appearance, not swelling, discoloration, or paleness.

4. If you are at the zenith of your career, you are ___________.

A. just getting started
B. preparing for retirement
C. at the pinnacle of success
D. having trouble with your superiors

Correct answer: C

Rationale: When someone is at the zenith of their career, it means they have reached the highest point or peak of success in their professional life. This suggests that they have achieved their utmost potential and are enjoying the height of their career accomplishments. Choice A, 'just getting started,' is incorrect as it implies the beginning of a career rather than the peak. Choice B, 'preparing for retirement,' is incorrect because being at the zenith of one's career usually signifies the prime of one's professional success, not the preparation for retirement. Choice D, 'having trouble with your superiors,' is incorrect as it is unrelated to the concept of reaching the peak of success in one's career.

5. Choose the meaning of the word 'dilute' in the following sentence: 'Always dilute that medicine before administering it to a patient.'

A. Add water to
B. Reduce by half
C. Warm up
D. Decontaminate

Correct answer: A

Rationale: In this context, 'dilute' means to make the medicine less concentrated by adding water or another liquid. It is important to dilute certain medicines to ensure they are safe and effective for a patient's use. Choice B, 'Reduce by half,' is incorrect as diluting does not necessarily mean reducing by half; it means to make less concentrated. Choice C, 'Warm up,' is unrelated to the meaning of dilute. Choice D, 'Decontaminate,' is also incorrect as dilute refers to reducing the concentration of a substance, not removing contaminants.
