Question textSection E: Read this paragraph and answer the following questions. Space junk has become a serious issue. It is estimated that there are 3,000 obsolete satellites orbiting in space at any time, and this problem is worsening each time a new satellite leaves Earth. Unlike litter on Earth, space junk, which includes small pieces of paint from rockets and other metal objects, can travel extremely fast, up to 27,000 kph. This poses a threat, not only to astronauts, their spacecraft and active satellites, but also to inhabitants on Earth. Although there have been no fatalities so far from falling space litter, there are few locations remaining where it can land without causing harm. Potential solutions to remove the junk safely from space include using nets, magnets and lasers. However, these methods would not be successful for smaller objects re-entering the earth’s atmosphere. The problem of space junk is an international one, that may threaten future space exploration missions and put humans at risk. Questions 12-14. Which of the following ideas are mentioned in the text?
