1. In the context of cholesterol levels, LDL cholesterol is often referred to as:

• A. HDL or "good" cholesterol.
• B. LDL or "bad" cholesterol.
• C. Total cholesterol, encompassing both LDL and HDL.
• D. VLDL, a type of triglyceride transported in the bloodstream.

Correct answer: B

Rationale: LDL cholesterol is often referred to as "bad" cholesterol because high levels of LDL can lead to plaque buildup in the arteries, increasing the risk of heart disease and stroke. LDL cholesterol is considered harmful as it contributes to the formation of plaque in blood vessels, whereas HDL cholesterol helps remove LDL from the arteries. Choice A is incorrect because HDL is known as "good" cholesterol, which helps remove LDL cholesterol from the bloodstream. Choice C is incorrect as it refers to total cholesterol, which includes LDL, HDL, and other lipids. Choice D is incorrect as VLDL is a different type of lipoprotein that carries triglycerides and is not specifically related to LDL cholesterol.

2. Which of the following sentences correctly uses apostrophes?

• A. Our home's roof needs repairing.
• B. My grandparents' families are coming to town for the holidays.
• C. There are many parks located across the country.
• D. All of the women's things were lost at sea.

Correct answer: A

Rationale: Choice A, 'Our home's roof needs repairing,' is the correct answer as it correctly uses the apostrophe to indicate possession. In this sentence, the apostrophe is used to show that the roof belongs to the home. Choice B is incorrect because it should be 'My grandparents' families' to show that multiple families belong to the grandparents. Choice C is incorrect as the sentence should be 'There are many parks located across the country' without using an apostrophe. Choice D is incorrect because it should be 'All of the women's things' to indicate possession by the women.

3. What is the mode of the data set: 2, 3, 3, 4, 4, 4, 5?

• A. 2
• B. 3
• C. 4
• D. 5

Correct answer: C

Rationale: The mode of a data set is the value that appears most frequently. In this data set (2, 3, 3, 4, 4, 4, 5), the number 4 appears three times, which is more frequent than any other number in the set. Therefore, the correct answer is 4. Choice A (2), B (3), and D (5) do not appear as frequently as 4 in the data set, so they are not the mode.

4. Based on the context of the passage, the reader can infer that this information is likely to appear in which of the following types of works?

• A. a scholarly paper
• B. a mystery
• C. a fictional story
• D. a biography

Correct answer: D

Rationale: The information provided in the passage about the skeleton's structure and divisions, along with specific details like the number of bones and their functions, is characteristic of content found in a biography or a reference work focusing on anatomy. Biographies often include detailed factual information about historical figures, their lives, and aspects related to them, such as physical characteristics. A scholarly paper would delve deeper into analysis and research, rather than presenting basic factual information. The content in the passage is purely informative and factual, ruling out the possibility of it being part of a mystery or fictional story, which require narrative and plot elements rather than straightforward facts.

5. The swirling snow drifted down all afternoon. Which of the following parts of speech is 'swirling' as used in the sentence above?

• A. Interjection
• B. Article
• C. Adjective
• D. Adverb

Correct answer: C

Rationale: In the sentence 'The swirling snow drifted down all afternoon,' 'swirling' is functioning as an adjective. Adjectives modify or describe nouns, and in this case, 'swirling' describes the noun 'snow.' The word 'swirling' is giving more information about the nature or quality of the snow, indicating that it is moving in a circular motion. Choices A, B, and D are incorrect. An interjection is a word or phrase used to express strong emotions or sentiments, which 'swirling' does not do in this context. An article is a determiner that introduces a noun, and 'swirling' is not serving this function. An adverb typically modifies a verb, adjective, or another adverb, but in this sentence, 'swirling' is not modifying a verb, making it an incorrect choice.
