Question

Which BEST states the main idea of the first paragraph?

Should we explore space? Some people say no because it costs too much, and there are problems on Earth that we must solve. Others say yes. One reason they give is how much the space program benefits us on Earth. It has brought us great things we use every day!

The space program has led to many new items for our health. Do you wear invisible braces? If so, you can thank space program scientists. They came up with the technology that made them possible. They also came up with ideas that led to eyeglass lenses that don't scratch. The sneakers you wear might have more spring and be better for your feet because of the space program, too. That's because some sneaker companies now use moon boot technology.

Today we take it for granted that we can call anyone anywhere on the globe. But we need to thank the space program for that, too. It came up with the satellites that send voices around the world.

There are many problems here on Earth that we have to solve.
