Some people think it's a waste of resources, but there are many good reasons to look up at the stars. First, space exploration helps us make new technologies. Many everyday things, like GPS, memory foam pillows, and even water purification systems, came from space research. When scientists solve problems for astronauts, they often create tools that help people on Earth too. Second, we need to find new resources. Earth's oil, gas, and minerals will not last forever. The moon has helium­3, a clean energy source that could power our planet for thousands of years. Asteroids also have valuable metals that we can use. Third, exploring space helps us understand our planet better. Satellites take pictures of Earth that show climate change, natural disasters, and pollution. This information helps us protect the environment and save lives. Finally, space exploration brings people together. Countries like the United States, Russia, and China work together on the International Space Station. When we look at Earth from space, we see that we are all one people, not just citizens of different countries. Space exploration is not just about rockets and astronauts. It's about making life better for everyone on Earth. 根据短文内容，选择最佳答案。 (C)1.Why does the author mention the questions in paragraph 1? A．To express his doubts. B．To compare different ideas.
