Part H: Choose the best answer for each question according to the passage.   We know that dinosaurs ruled the Earth for about 180 million years. Then, around 66 million years ago, ahuge rock from outer space (called an asteroid) smashed into the Earth. It crash-landed near Mexico. The asteroid made lots of dust and dirt and rocks to fly up into the air. All thatdust and dirt covered the planet and made the sky dark. There were many forest fires too. There were also lotsof volcanoes erupting in what we now call India. They made smoke, and ash, and gases fill up the air. It wasso dusty and dark that the warm sunshine couldn’t reach the ground. This made the Earth very cold.But after the dust settled and the sun came out, the Earth got very hot indeed. The sea creatures, plants, andland animals didn’t like that very much. The plants probably had a hard time growing. The plant-eatinganimals ran out of plants to eat, and then the animals that ate other animals also ran out of food. So it becamevery hard for dinosaurs to survive, and eventually the survivors of the asteroid crash ran out of food andstarved.
