Question

orbital debris is a fancy name for the junk that orbits earth. abandoned launch vehicles are examples of orbital debris. this space junk can collide with spacecraft and poses particular risks to the international space station (iss). as a result, nasa tracks space junk as it orbits earth. to protect against pieces of debris that are smaller than a half inch, the iss has debris shields. for larger pieces of debris, however, nasa follows a set of guidelines. sometimes astronauts are aware of the debris in advance. when this is the case, nasa may avoid collisions by slightly moving the iss. other times, large debris makes a surprise approach. in this case, the iss crew may respond by moving into the soyuz spacecraft, which serves as a lifeboat in case of emergency.
match the problems with their solutions.
shields offer protection.
the iss crew enters the soyuz.
the iss changes location.
problem
small debris can damage the iss.
large debris can be seen heading toward the iss.
large debris may not be detected in time.

Explanation:

Match each problem to the solution described in the passage:

1. Small debris can damage the ISS: The passage states the ISS has debris shields for debris smaller than a half inch.
2. Large debris can be seen heading toward the ISS: NASA can move the ISS slightly to avoid collisions with detected large debris.
3. Large debris may not be detected in time: The ISS crew uses the Soyuz as an emergency lifeboat for undetectable large debris surprises.

Answer:

Small debris can damage the ISS. → Shields offer protection.
Large debris can be seen heading toward the ISS. → The ISS changes location.
Large debris may not be detected in time. → The ISS crew enters the Soyuz.
