1. Which example shows correct comma usage for dates?

A. The due date for the final paper in the course is Monday, May 16.
B. Tuesday, March 10, 2021 was when the meeting took place.
C. We will meet on Friday, March 11, 2022.
D. We met on Monday, December 11, 2020.

Correct answer: A

Rationale: The correct answer is A because it uses a comma to separate the day of the week from the date, as well as a comma after the month when the date is included in a sentence. In choice B, there should be commas after both the day of the week and the date. Choice C correctly uses commas after the day of the week and the date. Choice D incorrectly places the comma before the date instead of after the month.

2. Which of the following sentences uses proper capitalization?

A. Last summer, my family went on a trip to Niagara Falls in New York.
B. Last summer, my family went on a trip to Niagara Falls in New York.
C. Last summer, my family went on a trip to Niagara Falls in New York.
D. Last summer, my family went on a trip to Niagara Falls in New York.

Correct answer: C

Rationale: The correct sentence uses lowercase 'summer' and capitalizes 'Niagara Falls.' Choice A incorrectly capitalizes 'Summer,' while Choice B incorrectly capitalizes 'niagara falls' and should have 'New York' capitalized. Choice D incorrectly capitalizes 'Summer' and 'new york.'

3. They were able to reach the deck fastest to get a seat on a lifeboat. Which of the following sentences is written correctly and provides a clear explanation?

A. Because the majority of survivors came from first class, they were able to reach the deck fastest to get a seat on a lifeboat.
B. Because of this, the majority of survivors came from first class, as they were able to reach the deck fastest to get a seat on a lifeboat.
C. Because of this, the majority of survivors came from first class, they were able to reach the deck fastest to get a seat on a lifeboat.
D. Because of this, the majority of survivors came from first class, as they were able to reach the deck fastest to get a seat on a lifeboat.

Correct answer: B

Rationale: Option B provides a clear and grammatically correct explanation for why the majority of survivors came from first class - they were able to reach the deck fastest to get a seat on a lifeboat. The phrase 'Because of this' properly introduces the reason that follows. In Option A, a comma after 'Because' is unnecessary and disrupts the flow of the sentence. In Option C, 'Because this' is incomplete and lacks proper connection to the subsequent clause. Option D, similar to Option C, lacks clarity due to the absence of a full linking phrase. Therefore, Option B is the best choice as it conveys the explanation effectively and without grammatical errors.

4. What is 0.075 mg converted to micrograms?

A. 75 mcg
B. 7.5 mcg
C. 0.75 mcg
D. 750 mcg

Correct answer: D

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 since there are 1000 micrograms in a milligram. Therefore, to convert 0.075 mg to mcg, you would multiply 0.075 by 1000, which equals 75. Thus, the correct conversion is 750 mcg. Choice A, 75 mcg, is incorrect as it's the result if you mistakenly multiply by 10 instead of 1000. Choice B, 7.5 mcg, is incorrect as it's the result if you divide by 10 instead of multiplying by 1000. Choice C, 0.75 mcg, is incorrect as it's the result if you divide by 100 instead of multiplying by 1000.

5. What cells compose the epidermis?

A. Keratinocytes
B. Epithelial cells
C. Fibroblasts
D. Melanocytes

Correct answer: A

Rationale: The correct answer is A - Keratinocytes. The epidermis is primarily composed of keratinocytes, which are a type of epithelial cell. Keratinocytes synthesize the protein keratin, providing protection against physical damage and water loss. While epithelial cells are correct, specifying keratinocytes is more precise. Fibroblasts are not the main cell type in the epidermis; they are found in the dermis, where they produce collagen and other extracellular matrix components. Melanocytes are responsible for producing melanin pigment in the skin and are also present in the epidermis, but they are not the predominant cell type like keratinocytes.
