Question

which best describes the purpose of the international space station? to conduct research to end wars to shield earth from asteroids to connect the world to space

Explanation:

The International Space Station (ISS) is a collaborative orbital platform designed primarily for scientific and technological research in microgravity, life sciences, physics, astronomy, and other fields. The other options are not aligned with its core purpose: it has no role in ending wars, does not function as an asteroid shield, and while it enables space access, its defining purpose is research.

Answer:

to conduct research
