Correct Answer: D

Rationale: The correct answer is D: 'Many.' The prefix poly- comes from the Greek word 'polus,' which means 'many.' Therefore, in the word polygon, poly- indicates a shape with many sides. Choices A, B, and C are incorrect because the prefix poly- does not mean 'few,' 'several,' or 'none,' but rather 'many.'

Correct Answer: C

Rationale: In this sentence, 'affect' is the correct verb meaning 'to influence,' and 'your' is the correct possessive pronoun. Therefore, the sentence should read, 'We cannot allow the budget cuts to affect the plans to improve education; the futures of your children are at stake.' Choice A is incorrect because 'effect' is a noun, not a verb, and 'your' is the correct possessive pronoun. Choice B is incorrect because 'you're' is a contraction for 'you are,' which does not make sense in this context. Choice D is incorrect because 'effect' should be 'affect' as the verb is needed to show influence.

Correct Answer: C

Rationale: The correct plural form of 'syllabus' is 'syllabi.' In English, when a word ends in -us, the plural form is often changed to -i. Therefore, 'Syllabi' is the correct plural form. Choice A, 'Syllabus,' is the singular form, not the plural. Choice B, 'Syllaba,' does not follow the standard pluralization rule for words ending in -us. Choice D, 'Syllabis,' is an incorrect plural form that does not follow the standard English pluralization rules.

Correct Answer: C

Rationale: Option C is the correct answer as it correctly separates the cities and states in the series using commas. The items in a series should be separated by commas, with the final two items being separated by 'and.' Choices A, B, and D have incorrect punctuation or lack necessary commas. In Choice A, semicolons are used incorrectly, and in Choice B, semicolons are placed inappropriately. Choice D lacks necessary commas to separate the cities and states effectively. Therefore, Option C is the only choice that demonstrates the correct way to separate items in a series.

Correct Answer: D

Rationale: Option D is the correct answer as it uses a semicolon to correctly separate two independent clauses. In this sentence, 'Beatrice is very intelligent' and 'she just does not apply herself well enough in her classes to make good grades' are two independent clauses that are related but can stand alone as separate sentences. The semicolon is the appropriate punctuation mark to link these two closely related ideas. Choices A, B, and C are incorrect because they either use a comma splice (A), a colon (B), or lack appropriate punctuation (C) to separate the independent clauses.
