Explanation:
The text presented includes multiple details about the activities astronauts doe while being in a space station or while being in the space especially as the workday ends such as sleeping for eight hours, covering the windows and attaching the sleeping bags about this last detail it can be inferred the reason why astronauts attach the sleeping bags is "to prevent them from floating in their sleep" because this text is related to the context of the space and it is general knowledge in the space and even insider spatial stations there is no gravity and this causes everything floats if it is not attached including astronauts and sleeping bags.
