Correct Answer: A

Rationale: The correct answer is A: "I'm counting on you to finish this before the deadline." This sentence is classified as informal language due to the use of contractions (I'm) and the casual tone of the phrase. The other choices (B, C, D) are more formal in nature. Choice B uses formal language with terms like 'non-negotiable.' Choice C is a general statement about meeting a deadline without any informal language, and choice D discusses the significance of the time period before a deadline in a formal manner.

Correct Answer: C

Rationale: When a colon is used to introduce a list, it is placed after a complete sentence and serves to signal that what follows will be a list or an explanation related to the preceding sentence. Choice A is incorrect because a colon doesn't join two related sentences; it introduces what follows after a complete sentence. Choice B is incorrect as a colon is not used to set off direct quotes longer than five words; quotation marks are used for that purpose. Choice D is incorrect because a colon does not separate clauses in a compound sentence; it is used to introduce a list or explanation after a complete sentence.

Correct Answer: D

Rationale: Bi, re, and un are prefixes, not suffixes. Prefixes are added at the beginning of base words to change their meanings. Therefore, choices A, B, and C are incorrect because they refer to suffixes or emphasize, which is not the case for these prefixes.

Correct Answer: C

Rationale: The correct answer is C. 'Therefore,' 'because,' and 'accordingly' are examples of cause-and-effect signal words. These words indicate a relationship between actions or events where one causes or results in another. Choice A, 'Emphasis words,' is incorrect as the given signal words do not emphasize a point but rather show cause and effect. Choice B, 'Compare/contrast words,' is incorrect as these signal words do not indicate a comparison or contrast between two ideas. Choice D, 'Temporal sequencing words,' is incorrect as the signal words provided do not specifically denote a sequence of events over time, but rather a cause-and-effect relationship.

Correct Answer: B

Rationale: The correct answer is B. Titles used before names, like 'Uncle' in 'Uncle Archibald,' should be capitalized. In choices A, C, and D, 'cousin,' 'mother,' and 'sister' are common nouns and should not be capitalized unless used before the name as part of the title. Therefore, they are incorrect choices. Choice B demonstrates proper capitalization rules by capitalizing 'Uncle Archibald,' making it the correct option.
