1. What does ONEROUS mean?

A. Easy
B. Burdensome
C. Interesting
D. Relaxing

Correct answer: B

Rationale: The correct answer is B, 'Burdensome.' The term 'onerous' is used to describe something that is burdensome, oppressive, or difficult to deal with. Choices A, C, and D are incorrect because 'easy,' 'interesting,' and 'relaxing' do not convey the same meaning as 'onerous.'

2. What is the meaning of NEBULOUS?

A. Clear
B. Vague
C. Precise
D. Obvious

Correct answer: B

Rationale: The correct answer is B, 'Vague.' Nebulous means something that is vague or unclear. Choice A, 'Clear,' is incorrect as it represents the opposite meaning of nebulous. Choice C, 'Precise,' is incorrect as it denotes clarity and exactness, which is the opposite of nebulous. Choice D, 'Obvious,' is also incorrect as it implies something that is easily understood or seen, unlike nebulous which refers to something unclear or hazy.

3. Long before his death, Pablo Picasso became one of the most important artists in history.

A. become
B. became
C. been
D. had become

Correct answer: B

Rationale: The correct answer is 'Became.' In this sentence, we need the simple past tense 'became' to describe the action that occurred in the past. 'Become' (choice A) is incorrect as it is the base form of the verb and doesn't fit the sentence structure. 'Been' (choice C) is incorrect as it is the past participle and doesn't match the sentence context. 'Had become' (choice D) is unnecessary as the sentence doesn't require the past perfect tense.

C. burned
D. dizzy

Correct answer: D

Rationale: A vertiginous patient is dizzy. Vertigo is a sensation of spinning or dizziness that can be caused by various underlying medical conditions affecting the inner ear or brain. So, a vertiginous patient would be experiencing dizziness. Choices A, B, and C are incorrect as they do not accurately describe the condition of vertigo.

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.
