问题 What is the main idea of the passage? [br] The earliest dinosaurs lived in the time that was about ______ years from today according to the passage.

选项

答案 250 million

解析 本题空白处问“根据本文,最早的恐龙所生活的年代距今有多少年了”。文中最后一段提到“Sharks have existed for over 350 million years.They evolved over 100 million years before the dinosaurs did. (鲨鱼的存在已经超过了3亿5千万年,它们比恐龙还要早1亿年。)”据此推算,最早的恐龙应该生活在距今2亿5千万年的时代。因此答案为“250 million”。
