The following words share a common Greek-based suffix: anthropology, biology, cosmetology, etymology, and genealogy. What is the most likely meaning of the suffix -logy?

Correct Answer: B

Rationale: The correct answer is B: 'Study.' The suffix -logy is derived from the Greek word 'logia,' meaning 'the study of.' In words like anthropology (study of humans), biology (study of life), cosmetology (study of cosmetics), etymology (study of word origins), and genealogy (study of family history), the suffix -logy indicates a field of study or discipline. Choices A, C, and D are incorrect because the suffix -logy does not signify 'record,' 'science,' or 'technique,' but rather the concept of 'study' or 'science of.'

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.

Correct Answer: A

Rationale: The correct answer is A. In this sentence, the phrase 'who lives next door' is a non-essential element providing additional information about the teacher. It is correctly set off by commas. Choice B does not use any commas to set off the non-essential element, making the information essential to the sentence. Choice C uses an unnecessary comma before 'who,' which disrupts the flow of the sentence. Choice D incorrectly places the non-essential element at the end of the sentence without appropriate commas, making it less clear and concise.
