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. Which sentence correctly uses the word 'affect'?

A. The medication had no effect on the patient's symptoms
B. The noise did not affect his sleep
C. The bright light will affect your eyes
D. The cold weather did not affect her mood

Correct answer: B

Rationale: The correct use of 'affect' is to show influence or make a difference. In this context, 'The noise did not affect his sleep' is the correct usage as noise can impact one's ability to sleep. Choice A is incorrect as 'affect' is commonly confused with 'effect.' Choice C is incorrect as 'affect' is not typically used to refer to the impact of light on eyes. Choice D is incorrect as 'affect' is not typically used to describe the impact of weather on mood.

3. What does it mean if a theory is obsolete?

A. Advanced
B. Outdated
C. Useful
D. Innovative

Correct answer: B

Rationale: If a theory is considered obsolete, it means that it is outdated and no longer in current use or practice. Choice A, 'Advanced,' is incorrect as it implies progression rather than obsolescence. Choice C, 'Useful,' is incorrect because an obsolete theory is no longer considered useful due to being outdated. Choice D, 'Innovative,' is incorrect as it suggests newness and originality, which are opposite to being obsolete.

4. Another word for SITE is?

A. Severity
B. Location
C. Fortunate
D. Appearance

Correct answer: B

Rationale: Another word for 'SITE' is 'Location.' In this context, 'site' typically refers to a place or area, making 'Location' the most appropriate synonym among the given choices. Choice A, 'Severity,' does not relate to the meaning of 'site' as a place or area. Choice C, 'Fortunate,' and Choice D, 'Appearance,' are also unrelated to the concept of 'site,' making them incorrect choices.

5. Select the meaning of the underlined word in the following sentence. We will do more tests, as the data so far are inconclusive.

A. Unsettled
B. Convincing
C. Unfavorable
D. Bewildering

Correct answer: A

Rationale: The word 'inconclusive' in the sentence describes the data as not definitive or final, indicating that further tests are needed to reach a solid conclusion. 'Inconclusive' means not leading to a firm decision or result, making 'unsettled' the most suitable synonym in this context. Choice B, 'convincing,' does not align with the meaning of 'inconclusive' as it suggests that the data is already clear and persuasive, which contradicts the context. Choice C, 'unfavorable,' is not the best fit as 'inconclusive' does not imply a negative or unfavorable outcome but rather indicates a lack of a definitive answer. Choice D, 'bewildering,' does not capture the meaning of 'inconclusive' in this context. Bewildering implies confusion or puzzlement, which is not the intended meaning in the sentence.
