1. How many micrograms (mcg) are equivalent to 0.5 milligrams (mg)?

• A. 500 mcg
• B. 50 mcg
• C. 5 mcg
• D. 0.5 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 because there are 1000 micrograms in 1 milligram. Therefore, 0.5 mg x 1000 = 500 mcg. This conversion is crucial in medication dosage calculations to ensure precise administration. Choice B, 50 mcg, is incorrect as it represents 0.05 mg. Choice C, 5 mcg, is incorrect as it corresponds to 0.005 mg. Choice D, 0.5 mcg, is incorrect because it is the same value as the initial amount in milligrams, rather than the converted value to micrograms.

2. Which of the following sources would be the best to understand the suspense genre better?

• A. A public library's digital catalog
• B. The online reviews of the genre
• C. A New York Times bestseller list
• D. An encyclopedia entry about the suspense genre

Correct answer: D

Rationale: The correct answer is D, an encyclopedia entry about the suspense genre. This choice would be the best source to understand the suspense genre better as it provides a comprehensive and detailed overview of the genre's history, characteristics, and key elements. Option A, a public library's digital catalog, may list suspense novels available but does not offer in-depth information about the genre itself. Option B, online reviews of the genre, are subjective opinions and may not provide a holistic view of the genre. Option C, a New York Times bestseller list, showcases popular titles but doesn't delve into the specifics of the suspense genre.

3. He had to fill out a health history ____ before seeing the doctor.

• A. questionnaire
• B. questionaire
• C. questionnare
• D. questionairre

Correct answer: A

Rationale: The correct answer is 'questionnaire.' A questionnaire is a set of questions used for gathering information. The incorrect choices B, C, and D have misspellings of the word 'questionnaire.' 'Questionaire,' 'questionnare,' and 'questionairre' are not correct spellings and may lead to confusion or misunderstanding. It is essential to use the correct spelling to ensure clear communication in healthcare settings.

4. What is the general formula for an alcohol?

• A. CₙH₂ₙ
• B. CₙH₂ₙ₊₂
• C. CₙH₂ₙ₋₁
• D. CₙH₂ₙO

Correct answer: D

Rationale: The correct general formula for an alcohol is CnH2n+1OH, which can be simplified to CnH2nO. In this formula, 'n' represents the number of carbon atoms, '2n' represents the number of hydrogen atoms, and 'O' represents the oxygen atom present in the hydroxyl group of the alcohol. Therefore, the correct general formula for an alcohol is CnH2nO. Choice A, CₙH₂ₙ, does not account for the oxygen atom, which is essential in alcohols. Choice B, CₙH₂ₙ₊₂, does not include the oxygen atom or the necessary hydrogen atoms for the hydroxyl group. Choice C, CₙH₂ₙ₋₁, lacks the oxygen atom and also does not fulfill the requirements of the hydroxyl group. Thus, the most accurate representation of the general formula for an alcohol is CnH2nO.

5. Which sentence correctly answers the question: What were you doing when the thunderstorm started?

• A. I mowed the lawn.
• B. I am mowing the lawn.
• C. I was mowing the lawn.
• D. I have mowed the lawn.

Correct answer: C

Rationale: The correct answer is 'C: I was mowing the lawn.' This sentence correctly uses the past continuous tense to indicate an action that was in progress at a specific time in the past when the thunderstorm started. Choice A 'I mowed the lawn' is in simple past tense, not past continuous, and does not convey the ongoing nature of the action. Choice B 'I am mowing the lawn' is in present continuous tense, not past continuous, and does not match the past timeframe. Choice D 'I have mowed the lawn' is in present perfect tense, not past continuous, and does not convey the ongoing action at a specific past time.
