Answer the following question given this paragraph: Figure below shows a simple diagram of the expanding universe. Imagine a balloon covered with tiny dots. When you blow up the balloon, the rubber stretches. The dots slowly move away from each other as the space between them increases. In an expanding universe, the space between galaxies is expanding. We see this as the other galaxies moving away from us. We also see that galaxies farther away from us move away faster than nearby galaxies. Q: How does the distance between galaxies change as the universe expands? Choices: - it decreases - it is unchanged - it becomes irrelevant - it increases A:
A:
it increases
