Which of the following sentences uses proper capitalization?

Correct Answer: C

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: C

Rationale: Combining the sentences is most effective when using 'but' to contrast the two ideas. Option C is concise, clear, and provides the best flow, accurately capturing both the contrast 'but I lost them' and the sequence of events 'After spending hours looking for them, I found them in the freezer.' Options A, B, and D do not effectively combine the sentences or maintain the sequence of events and contrast between keeping track of the keys and losing them.

Correct Answer: D

Rationale: The suffix '-ize' is used to form verbs by converting nouns or adjectives into verbs. For example, 'real' can become 'realize' or 'modern' can become 'modernize.' On the other hand, the suffixes '-ation,' '-ness,' and '-ity' are commonly used to form nouns. '-ation' is often used to form nouns from verbs (e.g., 'celebrate' to 'celebration'), '-ness' is used to form abstract nouns from adjectives (e.g., 'kind' to 'kindness'), and '-ity' is used to form abstract nouns from adjectives (e.g., 'happy' to 'happiness'). Therefore, the correct answer is 'D' because '-ize' is not commonly used to form a noun from some other part of speech.

Correct Answer: C

Rationale: The correct answer, option C, effectively clarifies the communication structure by specifying who is communicating with whom and when. Tanya instructs her sister to convey a message to her boyfriend Joe, requesting him to call Tanya upon his arrival home. This revision removes the ambiguity present in the original sentence. Option A is incorrect as it introduces unnecessary complexity and alters the original meaning. Option B is incorrect as it misinterprets the relationships among the individuals involved. Option D is incorrect as it changes the dynamics of the communication and does not address the ambiguity in the original sentence.

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.
