Question

review the details below.

• while venus has surface temperatures that are hot enough to melt lead, the average temperature on mars is -67°f.
• mars has no liquid water on its surface today, though robotic rovers have confirmed that it did at some point in the past.
• 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.
venus and mars are close to the earth, but their
temperatures are too hot for humans.
the planets closest to earth have inhospitable conditions that
cannot support human life.
some planets close to the earth may have supported life in
the past, but they dont now.

Explanation:

• Analyze Option 1: It says Mars' temp is too hot, but Mars' avg temp is -67°F (cold), so this is incorrect.
• Analyze Option 2: The details show Venus has extreme heat and pressure, Mars has no liquid water now (inhospitable conditions). Both are close to Earth and conditions don't support human life. This matches.
• Analyze Option 3: The details focus on current inhospitable conditions (Venus' heat/pressure, Mars' no liquid water now), not past life support for all close planets. So incorrect.

Answer:

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