Our journeys into outer space brought us closer to understanding the universe. They also left behind numerous pieces of garbage known as “space junk” that pose threats to spacecrafts and space stations. This orbiting dump includes thousands of nuts, bolts, gloves, and other debris. Data from a 1999 study indicate there around 110,000 objects larger than 1 centimeter orbiting the Earth left from our ventures into space. Even the smallest of these could do serious harm to a satellite or space-based telescope. It could also threaten the lives of those aboard the International Space Station. U. S. Space Command takes responsibility for keeping an eye on space junk. This agency reports any potential threat to NASA, which sometimes must order emergency maneuvers to avoid space collisions. Which sentence could be added to support the author's claim that space junk is hazardous? A.
