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. An alarm that is strident is ___________.

A. shrill
B. muted
C. constant
D. resonant

Correct answer: A

Rationale: A strident alarm is loud, harsh, and piercing. The word 'shrill' specifically denotes a high-pitched and piercing sound, which aligns well with the characteristics of a strident alarm. Therefore, 'shrill' is the most suitable answer in this context. Choices B, C, and D are incorrect because a strident alarm is not quiet (muted), unchanging (constant), or deep and full (resonant), but rather loud and harsh.

3. What does the word Trepidation mean?

A. Fear
B. Misgivings
C. Confidence
D. Doubt

Correct answer: B

Rationale: The correct answer is B: 'Misgivings'. Trepidation is defined as a feeling of fear or anxiety about something that may happen. Choice A ('Fear') is too broad and does not capture the specific sense of unease that trepidation conveys. Choice C ('Confidence') is the opposite of what trepidation represents. Choice D ('Doubt') is related to uncertainty but does not fully encapsulate the sense of fear and anxiety associated with trepidation.

4. Choose the meaning of the word 'waft' in the following sentence: The steady breeze caused dry leaves to waft over the creek.

A. Sink
B. Dive
C. Wave
D. Float

Correct answer: D

Rationale: In this sentence, the word 'waft' is used to describe the movement of dry leaves over the creek in response to the steady breeze. 'Waft' means to float gently through the air. The correct meaning of 'waft' in this context is to float. Choices A, B, and C are incorrect because 'sink' means to go down below the surface of something, 'dive' means to plunge headfirst into water or another substance, and 'wave' means to move one's hand to and fro in greeting or as a signal.
