In 2021, a model developed by astrophysicist Catherine Zucker and her research team revealed that the same supernovas responsible for the creation and ongoing expansion of the Local Bubble—a 14-million-year-old cavity in the Milky Way—are likely responsible for the formation of new stars. _______this model detailed how the bubble’s expansion trapped interstellar clouds of gas and dust that became stars upon their eventual collapse. Which choice completes the text with the most logical transition?
Correct answer: D (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice D is the best answer. “Specifically” logically signals that the information in this sentence—that the Local Bubble’s expansion trapped clouds of gas and dust that formed new stars—provides specific, precise details elaborating on the more general information in the previous sentence about the relationship between the Local Bubble’s expansion and the formation of new stars. 28 SAT PRACTICE TEST #7 ANSWER EXPLANATIONS SAT ANSWER EXPLANATIONS n READING AND WRITING: MODULE 2 Choice A is incorrect because “hence” illogically signals that the information in this sentence is a result of the information in the previous sentence about the relationship between the Local Bubble’s expansion and the formation of new stars. Instead, this sentence provides specific, precise details elaborating on that information. Choice B is incorrect because “however” illogically signals that the information in this sentence contrasts with the information in the previous sentence about the relationship between the Local Bubble’s expansion and the formation of new stars. Instead, this sentence provides specific, precise details elaborating on that information. Choice C is incorrect because “admittedly” illogically signals that the information in this sentence provides an exception or caveat to the previous information about the relationship between the Local Bubble’s expansion and the formation of new stars. Instead, this sentence provides specific, precise details elaborating on that information.
