The patient's preoperative evaluation is scheduled for next Wednesday. In the sentence, the prefix pre- indicates that the evaluation will take place at which of the following times?

Correct Answer: A

Rationale: The prefix 'pre-' typically means before. In this case, 'preoperative' refers to activities that occur before an operation. Therefore, the patient's preoperative evaluation, scheduled for next Wednesday, will take place before the operation. Choices B, C, and D are incorrect because the prefix 'pre-' specifically indicates a time before the operation, not after, during, or outside of it.

Correct Answer: C

Rationale: Sentence C correctly maintains the pronoun-antecedent agreement. In this sentence, the antecedent is 'number of people,' and the pronoun 'it' is used to refer back to this antecedent. The singular pronoun 'it' matches the singular antecedent 'number,' making the sentence grammatically correct. Choice A is incorrect because it uses the plural pronoun 'they' to refer back to the singular antecedent 'storm.' Choice B is incorrect as it uses the plural pronoun 'they' to refer back to the singular antecedent 'each of the cars.' Choice D is incorrect because it uses the singular pronoun 'he or she' to refer back to the plural antecedent 'many people.' This creates a lack of agreement between the pronoun and its antecedent.

Correct Answer: C

Rationale: In the sentence, 'widely' is used as an adverb. It modifies the adjective 'available,' describing the extent to which professional dental care is available. An adverb can modify verbs, adjectives, or other adverbs. In this case, 'widely' modifies the adjective 'available,' making it an adverb. Choice A, 'adjective,' is incorrect because 'widely' is not describing a noun. Choice B, 'noun,' is incorrect because 'widely' is not a noun. Choice D, 'verb,' is incorrect because 'widely' is not being used as a verb in the sentence.

Correct Answer: D

Rationale: The correct plural form of 'potato' is 'potatoes.' In English, most plural nouns form by adding '-es' or simply '-s' to the singular form. Therefore, 'potatoes' is the correctly formed plural noun in this list. The other choices, 'vertebrae,' 'geese,' and 'octopuses,' are the correct plural forms of 'vertebra,' 'goose,' and 'octopus,' respectively. They demonstrate the common rule of adding '-es' or '-s' to form plural nouns.

Correct Answer: A

Rationale: The prefix 'pre-' typically means before. In this case, 'preoperative' refers to activities that occur before an operation. Therefore, the patient's preoperative evaluation, scheduled for next Wednesday, will take place before the operation. Choices B, C, and D are incorrect because the prefix 'pre-' specifically indicates a time before the operation, not after, during, or outside of it.

Correct Answer: B

Rationale: The correct answer is B. In this phrase, the words 'Senator' and 'California' are capitalized correctly since they refer to a specific position and a proper noun, respectively. 'Senator' is capitalized as it is part of the title and 'California' is capitalized as a proper noun. Choice A is incorrect because 'President' should be capitalized when it precedes a specific name, like 'President Carter.' Choice C is incorrect because 'Aunt' and 'Uncle' are not proper nouns and should not be capitalized. Choice D is incorrect because only 'New Year's Eve' should be capitalized as it is a proper noun for the event.

Correct Answer: C

Rationale: The best way to revise and combine the underlined portion of the sentences is by using a semicolon to show a stronger connection between the two ideas. Using 'however' after the semicolon helps to contrast the innocuous superstition with the negative outcome that sometimes occurred, providing a smoother flow between the ideas. Choice A is incorrect as it lacks a proper conjunction or punctuation to connect the ideas. Choice B is incorrect as 'but' does not effectively contrast the ideas as 'however' does. Choice D is incorrect as a colon is used to introduce a list or explanation, which is not suitable in this context where a contrast is needed.

Correct Answer: A

Rationale: The correct answer is A: "intra-". The prefix "intra-" is used to indicate that something is inside or within. For example, "intracellular" means within a cell, and "intrapersonal" means within oneself. Choice B, "trans-", typically indicates across, beyond, or through, not inside or within. Choice C, "anti-", is used to indicate against or opposed to. Choice D, "hyper-", usually denotes excessive or above normal levels, not inside or within.

Correct Answer: B

Rationale: The correct punctuation in this case is to use a comma (,) to set off the nonrestrictive clause 'whose death shocked America in April of 2016.' This clause provides additional information about the artist Prince without changing the essential meaning of the sentence. Choice A has a semicolon (;) which is incorrect as it separates two closely related independent clauses. Choice C uses em dashes (-) which are incorrect as they should be used for emphasis or to set off information. Choice D uses a colon (:) which is incorrect as it introduces a list or an explanation, not additional information about the artist Prince. Therefore, the correctly punctuated sentence is: 'The artist Prince, whose death shocked America in April of 2016, was one of the most successful musical artists of the last century.'
