Most of the planets that have been discovered outside our solar system orbit G-type stars, like our Sun. In 2014, blank researchers identified a planet orbiting KELT-9, a B-type star more than twice as massive and nearly twice as hot as the Sun. Called KELT-9b, it is one of the hottest planets ever discovered.
Which choice completes the text with the most logical transition?
Explanation
Choice B is the best answer. The word “however” logically signals that the information in this sentence about the planet KELT-9b—that it orbits a B-type star—contrasts with the previous information about planets discovered outside our solar system. Most of these planets orbit G-type stars, not B-type stars.
Choice A is incorrect because “likewise” illogically signals that the information about the planet KELT-9b is similar to the previous information about most planets outside our solar system. Instead, it contrasts with that information. Choice C is incorrect because “therefore” illogically signals that the information about the planet KELT-9b is a result of the previous information about most planets outside our solar system. Instead, it contrasts with that information. Choice D is incorrect because “for example” illogically signals that the information about the planet KELT-9b is an example of the previous information about most planets outside our solar system. Instead, it contrasts with that information.
