Question

while some researchers have identified the planet kepler - 1552b as potentially habitable, its unlikely that humanity will be able to take advantage of its favorable conditions anytime soon - its 2,507 light years away. - humanity must first focus on making planets within our solar system more habitable. which choice completes the text with the most logical transition? a. for example, b. likewise, c. instead, d. next,

Explanation:

The text presents a situation where a planet (Kepler - 1552b) has potentially habitable conditions but is too far (2,507 light - years) for humanity to reach soon. The logical next step in such a scenario is to focus on what is within reach, i.e., planets in our solar system. "Next" implies a sequential, logical progression. "For example" is used for illustration, which is not the case here. "Likewise" is for similarity, and there's no such context. "Instead" implies a replacement, but the text is about a next step rather than a replacement.

Answer:

D. Next
