1. What has left tons of “space junk” in orbit around the earth?

robots sent on space missions

years of space exploration

lack of recycling

missiles in outer space

2. Countries around the world have agreed to limit the time their space tools stay in orbit to 25 years. As explained in the passage, what problem does this solution address?

the increasing amount of space junk in orbit around the earth

space agencies exploring space

Chinese efforts to blow up a satellite

objects moving around the planet at very high speed

3. Trash has become a problem in outer space too.

According to BBC News, there are more than 22,000 pieces of junk in space around the earth.

4. Why have countries agreed to build space tools that must fall safely into the earth’s atmosphere?

so that the tools can remove pollution from the atmosphere after returning from space

so that the tools burn up in the atmosphere and don’t become space junk

so that the tools pollute the atmosphere instead of outer space

so that the tools can analyze the different gases that make up the atmosphere after returning from space

5. What was the passage mostly about?

different missions scientists are trying in space

the effects that tiny pieces of space junk could have on the earth

the problem of space junk and scientists’ attempts to solve this problem

the problem of trash on planet Earth

6. Read the following sentences: “In our opinion the problem is very challenging and it's quite urgent as well,'’ said Marco Castronuovo, an Italian Space Agency researcher who is working to solve the problem.

unnecessary

needs immediate attention

minor
