Lời giải tham khảo:
Đáp án đúng: B
Dẫn chứng: Galileo was famous for his study of how things fall. He was the first person to do experiments about this problem. Before, people thought that heavy things always fell faster than light things. He found out that this was not true. He took a heavy ball and a light ball and he dropped them both from a high place. They fell at the same speed. This meant that weight is not important.
Chọn đáp án B. weight is not important.
