1. If a person can type 45 words per minute, how many words can they type in 20 minutes?

Correct answer: C

Rationale: To find out how many words a person can type in 20 minutes at a speed of 45 words per minute, you multiply the typing speed (45 words/minute) by the duration (20 minutes): 45 words/minute x 20 minutes = 900 words. Hence, the correct answer is 900 words. Choice A (800 words) is incorrect because it results from multiplying 45 words per minute by 18 minutes, not 20. Choice B (850 words) is incorrect as it is not the product of 45 words per minute and 20 minutes. Choice D (750 words) is incorrect because it is the outcome of multiplying 45 words per minute by 15 minutes, not 20.

2. What is 50% of 120?

Correct answer: D

Rationale: The correct answer is D, 60. To find 50% of 120, you multiply 0.5 by 120: 0.5 x 120 = 60. Choice A and B are incorrect as they are duplicates. Choice C, 70, is incorrect because it is not the result of calculating 50% of 120.

3. The word STAGGERED means .

Correct answer: C

Rationale: The word 'staggered' is associated with unsteadiness or imbalance in movement. Stumbling is the most suitable synonym among the given choices to convey this meaning. 'Fell,' 'fumbled,' and 'pirouetted' do not accurately capture the idea of unsteadiness or imbalance conveyed by the word 'staggered.' 'Fell' generally means coming down from a standing position, 'fumbled' implies clumsiness or mishandling, and 'pirouetted' refers to a specific graceful ballet move, none of which align with the meaning of 'staggered.'

4. Which of the following structures has the lowest blood pressure?

Correct answer: D

Rationale: Veins have the lowest blood pressure among the listed structures. This is because veins carry blood back to the heart at a slower rate compared to arteries, arterioles, and venules. The lower blood pressure in veins allows for the efficient return of blood to the heart despite the decreased pressure. Arteries have high blood pressure as they transport blood away from the heart at a rapid rate. Arterioles are smaller branches of arteries and contribute to resistance in the circulatory system, leading to a pressure drop. Venules are small blood vessels that collect blood from capillaries and gradually converge into veins, having slightly higher pressure than veins.

5. During a wellness workshop, a healthcare provider is collecting comprehensive health histories from attendees. One of the written questions on the history form states, 'You don't smoke, drink, or take drugs, do you?' This question is an example of:

Correct answer: C

Rationale: The question provided is an example of using biased or leading questions. It suggests that one answer is more socially acceptable or preferable than another, potentially pressuring the individual to respond in a specific way. This can result in inaccurate information being provided and may also evoke feelings of guilt or judgment, influencing the person's responses. Choices A, B, and D are incorrect as they do not accurately describe the nature of the question. The question does not involve talking too much, confrontation, or blunt language; instead, it leads the respondent towards a specific answer.
