Question
[114]. Read the following passage carefully:
Passage: "A space station is a large laboratory that circles the Earth hundreds of kilometres above the surface, travelling so fast that it completes one orbit in about ninety minutes. Inside, astronauts float because they are in continuous free fall around the planet, not because there is no gravity. They grow plants, study how the human body changes without weight, and test materials that behave differently in space. Supplies arrive by cargo spacecraft, and waste is carefully packed and removed. Life on the station is strictly scheduled, for a small mistake can endanger everyone. The station matters less as a place to live than as a workshop where scientists learn what long journeys beyond Earth would demand." What is the main idea of the passage?
