The correct answer is (D):
(1), (2) and (3) are mentioned in the second paragraph, refer to “diverse populations” - (2), “new ideas” - (1) and “infrastructure for finance, organization” - (3).
The correct answer is (B):
While (4) is beside the point, (1) does not address the question at hand. (3) goes contrary to received wisdom in the passage. (2) is explicitly mentioned in the third paragraph, refer to “what staunches creativity …. It's the very institutions”
The correct answer is (A):
Neither (2) nor (3) are mentioned as such in the passage. (4) is a recommendation, not the central idea of the passage. The passage is on creativity, and the central idea can be found in the first paragraph itself - “What fosters creativity? … the presence of other creative people”, a theme that resonates throughout the passage.
The correct answer is (C):
The alarming view in (2) is not echoed in the passage. (4) also runs contrary to the passage, Jane Jacobs argues in the fifth paragraph that all cities are filled with creative people. (1) is a lay opinion. Jane Jacobs argues that “some cities had more than their shares of leaders, people and institutions that blocked out that creativity”, hence we can safely infer that the more creative cities have leaders and institutions that do not block creativity.
The correct answer is (B):(1) again runs contrary to the passage, which places creativity as inversely proportional to age. (4) is not mentioned in the passage. (3) paints with too brand a brush. (2) is resonated in the third paragraph, “staunches creativity … many of our schools”.
The correct answer is (A):
(2) is not supported by the passage, refer to “the other 66 percent who toil” in the sixth paragraph. The recommendation in (3) is not the author's. (4) assumes that low-wage workers are creative, which is suspect. The author mentions “work which engages our creative faculties … those of us who work with our minds”, the assumption then being that those who work with their hands are not creative.
Read the sentence and infer the writer's tone: "The politician's speech was filled with lofty promises and little substance, a performance repeated every election season."
