what can you conclude about the international space station?
a without air pressure maintenance, air pressure in the international space station is different than in the earth’s surface.
b without air pressure maintenance, air pressure in the international space station is the same than in the earth’s surface.
c with air pressure maintenance, air pressure in the international space station is different than in the earth’s surface.
d with air pressure maintenance, there is no air pressure in the international space station.

Explanation:

To determine the correct conclusion about the International Space Station (ISS) regarding air pressure:

• Option A: "Without air pressure maintenance, air pressure in the ISS is different than Earth’s surface." This aligns with scientific knowledge: Earth’s surface has atmospheric pressure, while space (and the ISS without active pressure maintenance) is a near - vacuum, so air pressure in the ISS (without maintenance) would differ from Earth’s surface.
• Option B: Claims air pressure in the ISS (without maintenance) is the same as Earth’s surface, which is incorrect because space lacks significant air pressure.
• Option C: Mentions "with air pressure maintenance" but the comparison to Earth’s surface is illogical here—maintained ISS pressure is designed to be habitable (similar to Earth’s surface pressure for humans), so this is incorrect.
• Option D: States "with air pressure maintenance, there is no air pressure" which is contradictory—maintenance implies controlling pressure, not eliminating it.

Answer:

A. Without air pressure maintenance, air pressure in the International Space Station is different than in the earth’s surface.
