When studying vocabulary, a student notices that the words circumference, circumnavigate, and circumstance all begin with the prefix circum-. The student uses their knowledge of affixes to infer that all of these words share what related meaning?

Correct Answer: A

Rationale: The prefix circum- means 'around' or 'surrounding.' In words like circumference (the distance around a circle), circumnavigate (to travel around something), and circumstance (the conditions surrounding an event), the prefix implies the idea of being around or encompassing. Choices B, C, and D are incorrect because the words do not primarily relate to travel, size, or area; instead, they share the common theme of being around or surrounding something.

Correct Answer: C

Rationale: The key context clue essential to decipher the word 'ubiquitous' is the word 'now.' By comparing the rarity of automobiles a hundred years ago to their ubiquity now, the student can infer that 'ubiquitous' means something that is commonplace or found everywhere. Choice A ('Ago') refers to the past and does not provide information about the current state of cars. Choice B ('Cars') only contrasts rare and ubiquitous without indicating the change over time. Choice D ('Rare') simply contrasts with 'ubiquitous' without showing the transition from rarity to ubiquity.

Correct Answer: C

Rationale: The correct answer is C. 'Raze' is a homophone of 'raise,' which means to destroy completely. The other choices do not contain homophones. Choice A talks about a young woman walking on a canal path, choice B discusses water heating up and expanding, and choice D mentions a previous tenant who was a chemistry teacher, none of which involve homophones. Therefore, choice C is the only sentence that contains a homophone, making it the correct answer.

Correct Answer: C

Rationale: The comma after 'glasses' is used incorrectly in the sentence. Commas are not needed to separate the subject from the verb in this context. In this case, the subject 'She' is not separated from the verb 'wore,' making the comma unnecessary. The semicolon after 'book' is appropriate for separating two independent clauses, the comma after 'long' is correctly used for introductory elements, and the period at the end of the sentence is necessary for indicating the end of a complete thought.

Correct Answer: D

Rationale: The correct answer is 'Millennium.' 'Millennium' is spelled correctly, referring to a period of 1000 years. Choice A, 'Miniscool,' and Choice B, 'Miniature,' are misspelled. Choice C, 'Maintenance,' is a commonly misspelled word, but in this case, it is spelled correctly. However, the correct spelling requested in the question is 'Millennium.'
