Question

what is the gist of the passage in the box? people will probably visit someday, but would be too far away. options: earth, mars, andromeda

Explanation:

To determine the gist, we analyze the context. People visiting a celestial body someday, but another being too far. Earth is our home, so visiting it isn't a future "visit" in the same sense. Mars is a planet we aim to visit, and Andromeda is a galaxy (too far for human visits soon). The first blank: Mars is a feasible future visit target. The second blank (though options aren't fully shown, but from the first part) - Andromeda would be too far. But for the first dropdown, the correct choice is Mars as a place people will probably visit someday.

Answer:

First dropdown: Mars (from the options: Mars)
