Choice C is the best answer because it most closely maintains the sentence pattern established by the two preceding sentences, which begin with a noun and passive verb phrase (“A subway system is expanded,” “A bike-sharing program is adopted”).

Choice A is not the best answer because it does not maintain the sentence pattern established by the two preceding sentences. Rather, it begins the sentence with an infinitive phrase.

Choice B is not the best answer because it does not maintain the sentence pattern established by the two preceding sentences. Rather, it begins the sentence with a gerund.

Choice D is not the best answer because it does not maintain the sentence pattern established by the two preceding sentences. Rather, it shifts the placement of a modifying prepositional phrase, “in a congested downtown area,” from the end of the sentence to the beginning of the sentence.

Choice D is the best answer because it maintains agreement between pronoun (“it”) and antecedent (“any one”) and between subject (“any one”) and verb (“occurs”).

Choice A is not the best answer because the plural verb “occur” does not agree with the singular subject “any one.”

Choice B is not the best answer because the plural verb “occur” does not agree with the singular subject “any one” and because the plural pronoun “they” does not agree with the singular antecedent “any one.”

Choice C is not the best answer because the plural pronoun “they” does not agree with the singular antecedent “any one.”

Choice C is the best answer because “designing” maintains parallelism with “evaluating,” “assessing,” and “improving.”

Choice A is not the best answer because “they design” does not maintain parallelism with “evaluating,” “assessing,” and “improving.”

Choice B is not the best answer because “to design” does not maintain parallelism with “evaluating,” “assessing,” and “improving.”

Choice D is not the best answer because “design” does not maintain parallelism with “evaluating,” “assessing,” and “improving.”

Choice A is the best answer because it effectively signals the shift in the paragraph to the example of the work a transportation planner might perform if he or she were employed in a rural area and asked to consider the effects of building a new factory “on the outskirts of a small town.”

Choice B is not the best answer because noting that job opportunities are more plentiful in cities does not effectively signal the shift in the paragraph to the example of the work a transportation planner might perform if he or she were employed in a rural area.

Choice C is not the best answer because noting that most transportation planners work for government agencies does not effectively signal the shift in the paragraph to the example of the work a transportation planner might perform if he or she were employed in a rural area.

Choice D is not the best answer because the proposed deletion would create a jarring shift from the statement “Most transportation planners work in or near cities” to the example of the work a transportation planner might perform if he or she were employed in a rural area.

Choice B is the best answer because it correctly uses an apostrophe to indicate the possessive and doesn’t introduce any unnecessary punctuation.

Choice A is not the best answer because, while it correctly indicates the possessive relationship between “transportation planner” and “job,” it introduces an unnecessary comma after the word “job.”

Choice C is not the best answer because it doesn’t indicate the possessive relationship between “transportation planner” and “job,” and it introduces an unnecessary comma after the word “job.”

Choice D is not the best answer because it doesn’t indicate the possessive relationship between “transportation planner” and “job.”

Choice D is the best answer because it offers a clear and concise wording without redundancy.

Choice A is not the best answer because “current” is redundant with “at this time.”

Choice B is not the best answer because “current” is redundant with “right now.”

Choice C is not the best answer because “now” is redundant with “currently.”

Choice B is the best answer because the transitional phrase “For instance” logically indicates that what follows provides an example related to the previous sentence. “Representatives from the local public health department” is an example of the kinds of people with whom transportation planners work.

Choice A is not the best answer because the transitional word “Next” indicates sequence, which is not logical given that what follows provides an example related to the previous sentence.

Choice C is not the best answer because the transitional word “Furthermore” indicates addition, which is not logical given that what follows provides an example related to the previous sentence.

Choice D is not the best answer because the transitional word “Similarly” indicates comparison or likeness, which is not logical given that what follows provides an example related to the previous sentence.

Choice C is the best answer because it identifies the best reason the underlined sentence should not be kept. At this point in the passage and paragraph, a general statement about the benefits of walking only serves to interrupt the discussion of the community stakeholders with whom transportation planners work.

Choice A is not the best answer because the underlined sentence should not be kept. Although the sentence could theoretically provide supporting evidence about the benefits of walking, the passage has not made a claim that needs to be supported in this way, and including such a statement only serves to interrupt the discussion of the community stakeholders with whom transportation planners work.

Choice B is not the best answer because the underlined sentence should not be kept. Although the American Heart Association could theoretically be an example of “other interested organizations” that transportation planners work with, the sentence does not suggest this is the case. Instead, the association is merely the source for the general statement about the benefits of walking, a statement that only serves to interrupt the discussion of the actual community stakeholders with whom transportation planners work.

Choice D is not the best answer because although the underlined sentence should be deleted, it is not because the sentence lacks specific examples of the numerous benefits of walking. Adding such examples would only serve to blur the focus of the paragraph further with general factual information, as the paragraph’s main purpose is to discuss the community stakeholders with whom transportation planners work.

Choice A is the best answer because “who pursue careers in transportation planning” is, in context, a restrictive clause that should not be set off with punctuation. “Who pursue careers in transportation planning” is essential information defining who the “people” are.

Choice B is not the best answer because it incorrectly sets off the restrictive clause “who pursue careers in transportation planning” with commas as though the clause were nonrestrictive, or not essential to defining who the “people” are.

Choice C is not the best answer because it incorrectly sets off the essential sentence element “in transportation planning” with commas as though the phrase were not essential to the meaning of the sentence. “In transportation planning” is essential information defining what the “careers” are.

Choice D is not the best answer because it introduces an unnecessary comma after the word “planning,” incorrectly setting off the subject of the sentence (“people who pursue careers in transportation planning”) from the predicate (“have a wide variety of educational backgrounds”).

Choice A is the best answer because it uses a comma to effectively subordinate the list of varied fields in which transportation planners major.

Choice B is not the best answer because the comma and coordinating conjunction “and” result in an ungrammatical sentence.

Choice C is not the best answer because the coordinating conjunction “and” along with the subordinating conjunction “which” result in an ungrammatical sentence.

Choice D is not the best answer because is it unclear from this construction to what exactly the subordinating conjunction “which” refers.

Choice C is the best answer because it completes the sentence with an accurate interpretation of data in the graph. The graph displays projections of how much growth in employment there is expected to be between 2010 and 2020 for “social scientists and related workers,”for “urban and regional planners,” and in “all occupations” in the U.S. economy. According to the graph, the employment of urban and regional planners is expected to increase 16 percent between 2010 and 2020.

Choice A is not the best answer because the data in the graph do not support the claim that 16 percent of new jobs in all occupations will be related to urban and regional planning.

Choice B is not the best answer because the data in the graph do not support the claim that job growth in urban and regional planning will slow to 14 percent by 2020.

Choice D is not the best answer because the data in the graph do not support the claim that 14 to 18 percent of urban and regional planning positions will remain unfilled.

Choice D is the best answer because the simple present tense verb “watches” is consistent with the tense of the verbs in the rest of the sentence and paragraph.

Choice A is not the best answer because “watched” creates an inappropriate shift to the past tense.

Choice B is not the best answer because “had watched” creates an inappropriate shift to the past perfect tense.

Choice C is not the best answer because “would watch” creates an inappropriate shift that suggests a habitual aspect (other verbs in the sentence and paragraph, however, indicate that a specific instance is being narrated).

Choice B is the best answer because it provides punctuation that creates two grammatically complete and standard sentences.

Choice A is not the best answer because it results in a comma splice as well as some confusion about what the prepositional phrase “from just a few primary colors” modifies.

Choice C is not the best answer because it results in a run-on sentence as well as some confusion about what the prepositional phrase “from just a few primary colors” modifies.

Choice D is not the best answer because it results in a comma splice.

Choice B is the best answer because the colon after “parts” effectively signals that what follows in the sentence further defines what the “two parts” of Kingman’s name are and because the comma after “man” properly indicates that “‘king’ and ‘man’” and “Cantonese for ‘scenery’ and ‘composition’” are nonrestrictive appositives.

Choice A is not the best answer because the semicolon after “man” incorrectly joins an independent clause and a phrase. Moreover, the comma after “parts” is arguably a weak form of punctuation to be signaling the strong break in the sentence indicated here.

Choice C is not the best answer because the semicolon after “man” incorrectly joins an independent clause and a phrase and because the absence of a comma after “parts” fails to indicate that “two parts” and “‘king’ and ‘man’” are nonrestrictive appositives.

Choice D is not the best answer because the semicolon after “parts” incorrectly joins an independent clause and phrases and because the absence of a comma after “man” fails to indicate that “‘king’ and ‘man’” and “Cantonese for ‘scenery’ and ‘composition’” are nonrestrictive appositives.

Choice A is the best answer because it creates a comparison between like terms: “works” by Kingman and “paintings by Chinese landscape artists.”

Choice B is not the best answer because it creates a comparison between unlike terms: “works” by Kingman and “Chinese landscape artists.”

Choice C is not the best answer because it creates a comparison between unlike terms: “works” by Kingman and “painters of Chinese landscapes.”

Choice D is not the best answer because it creates a comparison between unlike terms: “works” by Kingman and “artists.”

Choice C is the best answer because “departed” is the most contextually appropriate way to indicate that Kingman had deviated from the tradition of Chinese landscape painting in a number of ways.

Choice A is not the best answer because while “vacated” does offer some sense of “leaving,” it would be awkward and unconventional to say that that a person was vacating from a tradition in a number of ways.

Choice B is not the best answer because while “evacuated” does offer some sense of “leaving,” it would be awkward and unconventional to say that a person was evacuating from a tradition in a number of ways.

Choice D is not the best answer because while “retired” does offer some sense of “leaving,” it would be awkward and unconventional to say that a person was retiring from a tradition in a number of ways.

Choice C is the best answer because placing sentence 3 after sentence 1 makes the paragraph most cohesive. Sentence 3 refers to Kingman’s “interest” being “so keen,” a continuation of the idea in sentence 1, which says that “Kingman was keenly interested in landscape painting from an early age.”

Choice A is not the best answer because leaving sentence 3 where it is now creates a sequence of sentences that lacks sufficient cohesion. Keeping sentence 3 in its current location disrupts the link between sentence 2 (which describes the concept of “school names” in Hong Kong) and sentence 4 (which reveals that Dong Kingman was the school name of Dong Moy Shu).

Choice B is not the best answer because placing sentence 3 before sentence 1 creates a sequence of sentences that lacks sufficient cohesion. Putting sentence 3 at the beginning of the paragraph would offer a poor introduction to the paragraph, in large part because sentence 3 builds directly on a point made in sentence 1.

Choice D is not the best answer because placing sentence 3 after sentence 4 creates a sequence of sentences that lacks sufficient cohesion. Putting sentence 3 after sentence 4 would disrupt the link between sentence 4 (which mentions that Dong Moy Shu was given the school name Dong Kingman) and sentence 5 (which explains what the two parts comprising the name Kingman mean in Cantonese).

Choice C is the best answer because it clearly establishes the main topic of the paragraph: Kingman’s urban landscapes.

Choice A is not the best answer because it would begin the paragraph with a loosely related detail about Kingman’s painting style and would not clearly establish the main topic of the paragraph.

Choice B is not the best answer because it would suggest that the main topic of the paragraph is the natural landscapes Kingman occasionally painted, which is incorrect given the focus of the rest of the sentences in the paragraph.

Choice D is not the best answer because it would begin the paragraph with a loosely related detail about Kingman’s life and would not clearly establish the main topic of the paragraph.
