Question

select the text that has a more objective tone.
no planet or star or galaxy can be typical, because the cosmos is mostly empty.
the only typical place is within the vast, cold, universal vacuum, the everlasting night of intergalactic space, a place so strange and desolate that, by comparison, planets and stars and galaxies seem achingly rare and lovely.
outer space is just what its name implies. it is the void that lies beyond the uppermost reaches of the atmosphere of earth and between all other objects in the universe . . . the principal environmental characteristic of outer space is the vacuum, or nearly total absence of gas molecules.
from carl sagan, cosmos, copyright 2002 by random house and from national aeronautics and space administration, \the outer space environment in suited for spacewalking\

Explanation:

The text about outer space (cosmos) describes its characteristics like being a vacuum, the absence of gas molecules, and its definition in a factual, unemotional way. It presents scientific information about the outer space environment, fitting the objective tone as it focuses on describing properties without personal feelings or opinions. The other text (not fully shown but the first part has more descriptive, almost poetic language with terms like "achingly rare and lovely" which is more subjective). So the text with the objective tone is the one starting with "Outer space is just what its name implies...".

Answer:

The text starting with "Outer space is just what its name implies. It is the void that lies beyond the uppermost reaches of the atmosphere of Earth and between all other objects in the universe... The principal environmental characteristic of outer space is the vacuum, or nearly total absence of gas molecules."
