Ques: Answer the following question given this paragraph: Stars are born in clouds like the one in the picture. Gravity pulls material together. When it is extremely dense, it begins nuclear fusion. That is, it becomes a star. We can see places where stars are being born right now. Of course, it takes light a long time to travel to us. So what we see right now may have happened many millions or even billions of years ago. Q: Stars are born in clouds, and they form and grow dense due to what force? Choices: - kinetic energy - Big Bang theory - coreolis effect - gravity A:
Ans: gravity
