1. Select the meaning of the underlined word in the following sentence. All volatile liquids should be stored and labeled correctly.

A. Unstable
B. Abnormal
C. Lethal
D. Blended

Correct answer: A

Rationale: In the context of the sentence, 'volatile' means likely to change rapidly and unpredictably or evaporate quickly. When referring to liquids, volatile typically implies that the liquids are unstable and can easily change from liquid to gas. Therefore, the most appropriate meaning of 'volatile' in this sentence is 'unstable.' Choices B, C, and D are incorrect because 'abnormal' and 'lethal' do not capture the essence of rapid change or evaporation associated with volatile liquids, while 'blended' is unrelated to the characteristics of volatile liquids described in the sentence.

2. What does it mean if a patient is lethargic?

A. Active
B. Exhausted
C. Confused
D. Restless

Correct answer: B

Rationale: Lethargic means feeling exhausted or sluggish. Being lethargic is the opposite of being active (choice A), confused (choice C), or restless (choice D). When a patient is lethargic, they lack energy and may appear tired or sluggish.

3. Before his death at age 82, comedian Rodney Dangerfield's motto was, 'I don't get _____.'

A. respect
B. sympathy
C. attention
D. care

Correct answer: A

Rationale: The correct answer is 'A: respect.' Rodney Dangerfield was famously known for his catchphrase 'I don't get no respect,' which perfectly aligns with the concept of respect being his motto. The other choices, 'B: sympathy,' 'C: attention,' and 'D: care,' do not accurately capture Dangerfield's well-known persona and catchphrase. Therefore, 'A: respect' is the most suitable answer.

4. What is another word for Asymmetric?

A. Even
B. Uneven
C. Identical
D. Matching

Correct answer: B

Rationale: The correct answer is B: 'Uneven.' Asymmetric means lacking symmetry or being uneven, so the term 'Uneven' is the most appropriate synonym. 'Even' (choice A) means equal or level, which is the opposite of asymmetric. 'Identical' (choice C) means similar or the same, and 'Matching' (choice D) means corresponding or fitting together, neither of which captures the meaning of asymmetric.

5. Precipitous is best defined as being ___________.

A. damp
B. gentle
C. swift
D. dull

Correct answer: C

Rationale: Precipitous is best defined as being swift, meaning sudden, rapid, or happening quickly. It is often used to describe a steep and very steep drop or rise. The word does not refer to being damp, gentle, or dull. 'Damp' means slightly wet, 'gentle' means mild or moderate, and 'dull' means lacking interest or excitement.
