Soru 1 |
Humans have evolved to work best in the atmosphere and gravity that exist on the Earth’s surface. To survive in space, astronauts have to take an Earth-like environment with them such as fresh oxygen, which is circulated around the craft for them to breathe. The main difference in space is the weightlessness causing astronauts to float around. As soon as astronauts go into space, their bodies start adapting to this weightlessness. Muscles, bones, heart and blood all undergo changes. At least half of all astronauts suffer an unpleasant reaction to weightlessness. On the Earth, gravity exerts a force on our bodies, which gives us weight and keeps us rooted to the ground. It also pulls body fluid downwards. In space, astronauts lose their sense of balance. They can feel sick, and go off their food. It can take two weeks for the digestive system to fully adjust. Therefore, NASA plans no spacewalks during the first three days of a mission, because an astronaut who vomits inside a spacesuit risks suffocation.
It is understood from the passage that ----.
gravity does not play any role in the proper
functioning of the human body | |
the unpleasant effects of weightlessness pass after
a few hours of exposure | |
almost all astronauts adapt quite well to the
conditions in space | |
astronauts can improve their sense of balance in the
weightless gravity of space thanks to their suits
| |
the human body experiences a negative reaction as
a result of weightlessness |

It is stated in the passage that ----.
the main difference between conditions in space
and on the Earth relates to the lack of oxygen
| |
human evolution will eventually allow humans to live
in the extreme conditions of space | |
one of NASA’s main aims in space travel is to
investigate ways in which the body adjusts to life in
space
| |
it takes time for some systems in the body to adjust
to the new conditions in space | |
it is possible to prevent the changes to the human
body in space through diet and exercise

humans to survive in space | |
lack of gravity has no significant biological effects on
the human body | |
the human body has evolved considerably to adapt
to the conditions of space | |
the conditions of the Earth’s surface challenge the
physical limits of the human body |

According to the passage, a possible danger during a mission is that astronauts may ----

problems
| |
feel tired because of physical stress and make
mistakes | |
lose their balance, fall down and get hurt | |
suffer from weight gain due to lack of exercise | |
throw up and choke inside their own spacesuits |
