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. The physician started to perform the operation, but the patient was not yet completely _____ anesthesia.

A. under
B. within
C. with
D. over

Correct answer: A

Rationale: The correct answer is 'under' as it is commonly used to describe the state of being affected by anesthesia. The patient is 'under' anesthesia, not 'within,' 'with,' or 'over' it. 'Within' typically refers to being inside something, 'with' indicates being accompanied by something, and 'over' suggests being above or on top of something. Therefore, in the context of the sentence, 'under' is the most appropriate choice.

5. What is the best meaning of Pernicious?

A. Harmless
