Question

read the excerpt from \moon mission.\ select two sentences in this excerpt that support the theme that avoiding waste is important. gateway will be smaller than the international space station. the iss is made up of 15 modules, or interlocking parts. gateway will have five modules. one or two of them, each about the size of a school bus, will house astronauts. another module will provide solar electric power, for propulsion. others will serve as an air lock for spacewalking astronauts and a docking port for vehicles. astronauts will travel to the moons surface and back in a smaller, reusable craft.

Explanation:

The sentence "Gateway will be smaller than the International Space Station" shows an effort to avoid excessive size (which could imply waste of resources in construction and operation). The sentence "Astronauts will travel to the moon's surface and back in a smaller, reusable craft" emphasizes reusability which is a key aspect of avoiding waste as it means the craft can be used multiple times instead of being a one - time, wasteful item.

Answer:

"Gateway will be smaller than the International Space Station" and "Astronauts will travel to the moon's surface and back in a smaller, reusable craft"
