Unfortunately, the belief that changelings could be convinced to leave was not just an innocuous superstition; however, on some occasions, harm came to the individual who was thought to be a changeling. Which is the best way to revise and combine the underlined portion of the sentences?

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 root word 'corp' is related to the body as it comes from the Latin word 'corpus,' meaning body. Words like 'corporal' and 'corporation' are derived from this root, linking them to the body in some manner. Choices B, C, and D are incorrect. 'Auto' relates to self or automatic, 'man' pertains to human or hand, and 'bio' is associated with life or living organisms, none of which directly signify the body.

Correct Answer: B

Rationale: In sentence B, "Ukrainians" is capitalized because it is referring to a specific group of people, and "Malanka" is also capitalized as it is a holiday name. This follows the rules of capitalization for proper nouns. Choices A, C, and D contain correct capitalization, but they also include additional capitalizations that are unnecessary. For instance, in choice A, "African white-backed vultures" should not be capitalized unless it is part of a proper noun or a title. In choice C, while "Neptune" and "Earth" should be capitalized as they are names of celestial bodies, the word "sun" is not capitalized unless it is used as part of the proper noun "Sun." Choice D correctly capitalizes proper nouns like "Edward Jenner" and "Immunology," but the general terms like "Father" and "vaccine" do not need capitalization unless they are part of a title or a specific name.

Correct Answer: A

Rationale: The complete subject in a sentence includes all the words that describe the main focus of the sentence. In this case, the complete subject is "Sandra's principal reason for choosing the job" as it encompasses all the relevant details about Sandra and her reason for selecting the job. Choice A is the correct answer because it provides the most comprehensive and specific information, making it the complete subject. Choices B, C, and D are incorrect as they do not include all the necessary elements to form the complete subject and do not convey the full context of the sentence.

Correct Answer: B

Rationale: The correct answer is B: 'dollars.' 'Bucks' is a slang term for dollars. The use of 'bucks' in this sentence is informal and colloquial compared to the other word choices, making it the slang word in the sentence. 'Cost,' 'steep,' and 'tag' are all standard English words that are not considered slang in this context.

Correct Answer: C

Rationale: A complex sentence has one independent clause and at least one dependent clause connected by a subordinating conjunction or a relative pronoun. In choice C, the sentence 'Because the distance between stars in the galaxy is far greater than the distance between planets' is a dependent clause introduced by the subordinating conjunction 'Because,' while the rest of the sentence 'interstellar travel is expected to be an even bigger challenge than interplanetary exploration' forms the independent clause. This combination of an independent clause and a dependent clause makes choice C a complex sentence. Choices A, B, and D do not contain both an independent and dependent clause connected in the way that choice C does, thus they do not qualify as complex sentences.

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: 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: A

Rationale: A compound sentence consists of two or more independent clauses that are joined by coordinating conjunctions such as 'and,' 'but,' or 'or.' In choice A, the sentence contains two independent clauses separated by the coordinating conjunction 'and': 'Plague, generally not a major public health concern, actually continues to spread among rodent populations today' and 'it even occasionally makes its way into a human host.' Choice B is a complex sentence as it contains a dependent clause 'which seeks answers to humanity's questions about its past' and an independent clause 'is significantly helped by new technologies.' Choice C is a simple sentence with one independent clause: 'In the fight against obesity, countries around the world are imposing taxes on sodas and other sugary drinks in an effort to curb unhealthy habits.' Choice D is a complex sentence with a dependent clause 'Because the assassination of President John F. Kennedy continues to haunt and fascinate Americans' and an independent clause 'new movies, books, and television series about it are released every year.'
