Which of the following sentences from a paragraph about gingivitis is the topic sentence?
- A. Gingivitis can be reversed by daily brushing, flossing, and regular dental cleanings.
- B. Gingivitis is a mild form of gum disease, in which bacteria causes inflammation of the gums.
- C. With gingivitis, the gums become red and swollen and can bleed easily.
- D. If left untreated, gingivitis can cause periodontitis, in which the gums pull away from the teeth.
Correct Answer: B
Rationale: The topic sentence in a paragraph typically introduces the main idea or topic of the paragraph. In this case, choice B correctly serves as the topic sentence by clearly stating that gingivitis is a mild form of gum disease caused by bacteria that leads to inflammation of the gums. Choices A, C, and D provide additional information that supports or follows the main idea but do not present the overarching topic of the paragraph.

What is the main purpose of a thesis statement?
- A. To summarize the essay
- B. To state the main idea of the essay
- C. To ask a question
- D. To provide evidence
Correct Answer: B
Rationale: The main purpose of a thesis statement is to clearly state the main idea or argument of the essay. It serves as a roadmap for the reader, outlining the central point that the essay will address. Choice A, 'To summarize the essay,' is incorrect because while a thesis statement does provide a concise summary of the main point, its primary function is to present the main idea, not summarize the entire essay. Choice C, 'To ask a question,' is incorrect as a thesis statement is a declarative statement that asserts a position or argument rather than posing a question. Choice D, 'To provide evidence,' is incorrect because a thesis statement does not offer evidence but rather sets the direction and focus for the evidence that will be presented in the essay.

- B. Brainstorm interesting topics and ideas.
- C. Develop an organized outline of the topic.
- D. Cite the sources in your presentation.
Correct Answer: B
Rationale: The correct answer is B: Brainstorm interesting topics and ideas. Brainstorming is an essential initial step in the creative process of generating ideas for a group presentation. It allows team members to freely share thoughts, explore various angles, and come up with innovative concepts. Choice A, interviewing sources, typically comes after brainstorming to gather information. Choice C, developing an organized outline, usually follows brainstorming to structure the presentation content. Choice D, citing sources, is important but is not the first step in the idea generation process.

- B. Words that sound the same
- C. Synonyms
- D. Words with similar spellings
Correct Answer: B
Rationale: The correct definition of a homophone is a word that sounds the same as another word but has a different meaning and often different spelling.

Choice C, 'Synonyms,' is incorrect because homophones are not words with the same meaning. Choice D, 'Words with similar spellings,' is also incorrect as homophones may have different spellings.
What is the most likely context of the following conversation: 'Yup, you too... hey wait, what are you up to tonight, anyways?'
- A. A boss is asking an employee about their schedule to see if they can work late.
- B. A speaker is practicing a speech for a debate about working overtime.
- C. A friend is asking another friend about their plans for the evening.
- D. An investigator is discussing research on acceptable work schedules.
Correct Answer: C
Rationale: The informal tone and casual language, such as 'hey wait' and 'what are you up to tonight, anyways?' suggest that the speaker is a friend inquiring about the plans of another friend. This type of conversation is typical among peers and not in a professional setting, ruling out choices A and D. Choice B is incorrect because there is no indication of a debate or formal speech practice in the conversation.
Which of the following compound sentences is punctuated correctly?
- A. The Forlows would be spending two weeks in Greece and Turkey.
- B. She was awake the minute the sun came up; although she had been up late the night before.
- C. Diana stepped out into the rain, but she had to turn immediately back inside for an umbrella.
- D. Aziz was astonished; he had never seen horses in the wild before.
Correct Answer: D
Rationale: Choice D is the correct answer because it correctly punctuates the compound sentence with a semicolon separating the two independent clauses. The use of a semicolon is appropriate when two closely related independent clauses are joined without a coordinating conjunction. Choices A, B, and C have incorrect punctuation or conjunction usage. Choice A incorrectly uses a comma before 'and,' while Choice B uses 'though' which is not the best conjunction to join the two clauses. Choice C also lacks appropriate punctuation to separate the two independent clauses.
