Question

read a second text about living in space.
living in space poses unique problems for the health of the astronauts. without gravity to push against, astronauts muscles are no longer working as hard, if at all. if astronauts dont find a way to work out in a weightless environment, then they are at risk of losing muscle mass in a process called atrophy. to avoid this, space stations are equipped with exercise machines that can be operated without gravity, including a special bicycle and treadmill. exercise is a major health concern in space; two and a half hours are devoted to using those machines every day. as nasa employee dr. don hagan put it,
o other activity except eating and sleeping is given that much priority.\
select all the details that are included in the text.
living in space requires paying careful attention to health.
exercise equipment must be adapted for use in space.
no - gravity environments can lead to muscle atrophy.

not all food is suitable for bringing on spaceflights.

Explanation:

• It mentions space stations are equipped with exercise machines that can be operated without gravity (adapted for space use).
• It describes that without gravity, astronauts' muscles may atrophy (no - gravity leading to muscle atrophy).
• There is no mention in the text about astronauts' past and present food options or which foods are suitable for spaceflights.

Answer:

• Living in space requires paying careful attention to health.
• Exercise equipment must be adapted for use in space.
