Question

review the details below. mars has no liquid water on its surface today, though robotic rovers have confirmed that it did at some point in the past. while venus has surface temperatures that are hot enough to melt lead, the average temperature on mars is -67°f. venus is similar to earth in terms of size and mass, but its surface pressure is ninety times higher. choose the best topic sentence to introduce a paragraph containing these details. the planets closest to earth have inhospitable conditions that cannot support human life. venus and mars are close to the earth, but their temperatures are too hot for humans. some planets close to the earth may have supported life in the past, but they dont now.

Explanation:

The details mention Mars (no liquid water now, cold temperature) and Venus (extremely hot surface temperature, high surface pressure). These are conditions that make them inhospitable for human life. The first option “The planets closest to Earth have inhospitable conditions that cannot support human life” encompasses all the details (temperature, pressure, water - related) about Mars and Venus. The second option is incorrect as Mars is cold (\(- 67^{\circ}F\)). The third option only focuses on past life (only mentioned for Mars) and not on all the inhospitable conditions (like Venus' high pressure, Mars' cold temperature).

Answer:

The planets closest to Earth have inhospitable conditions that cannot support human life.
