While researching a topic, a student has taken the following notes: • In astronomy, the mass of stars can be described in units called solar masses. • One solar mass is roughly equal to the mass of the Sun. • The mass of the star Proxima Centauri is 0.122 solar masses. • The mass of the star Sirius A is 2.063 solar masses. The student wants to emphasize the mass of Sirius A. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Correct answer: D (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice D is the best answer. The sentence emphasizes the mass of Sirius A, noting that it has a mass of 2.063 solar masses and that it is larger than the Sun. Choice A is incorrect. The sentence makes a generalization about how the mass of stars can be measured; it doesn’t emphasize the mass of Sirius A. Choice B is incorrect. The sentence introduces solar masses as a unit of measurement; it doesn’t emphasize the mass of Sirius A. Choice C is incorrect. The sentence emphasizes the mass of Proxima Centauri, not the mass of Sirius A.
