Questions 7-12. Read the following passage and choose the correct answer.

Spacesuits help astronauts in many ways. The suits protect astronauts from getting too hot or cold and also give astronauts oxygen to breathe while they are working in space. The suits hold water to drink during spacewalks. They also keep astronauts from getting hurt by space dust. Space dust may not sound very dangerous, but when a tiny object is moving many times faster than a bullet, it can cause injury. Spacesuits also protect astronauts from radiation in space, and are equipped with special, gold-lined visors to protect astronauts’ eyes from bright sunlight. A spacesuit is made up of many parts. One part covers the astronaut’s chest. Another part covers the arms and connects to the gloves. The helmet protects the head. The last part covers the astronauts’ legs and feet. Some parts of the suit are made of many layers of material. Each layer does something different. Some keep oxygen in the suit while others protect astronauts from space dust. Under the suit, astronauts wear another piece of clothing. It covers their body except for the head, hands, and feet. Tubes are woven into it. Water flows through the tubes to keep the astronaut cool. On the back of the spacesuit is a backpack. The backpack holds oxygen so astronauts can breathe, and removes carbon dioxide that astronauts breathe out. The backpack supplies electricity for the suit, while a fan moves the oxygen through the spacesuit. A water tank holds the cooling water. Connected to the back of the suit is a tool called SAFER. SAFER has several small thruster jets. If an astronaut floats away from the space station, they could use SAFER to fly back.
