Oxford Discover Grammar Student Book 2 Answer Key © Oxford University Press 9 Unit 15 Page 74 B For centuries, we used horses for transportation. A horse is stronger than a person, and it can pull a wagon. The wagon’s wheels make a heavy load easier to pull. Then people started to use canals. Canal transportation was slow, but the boats carried more things. A canal boat is bigger and heavier than a wagon. The boat is on water. Water makes the heavy load easier to pull. A hundred years ago, canals and horses were very important. Now we don’t use horses. We use highways and trucks. Trucks have big engines. Trucks are stronger than horses. They can pull heavier loads. Trucks are faster than boats. C 1 stronger 2 bigger, heavier 3 stronger 4 faster Page 75 E 1 bigger 2 shorter 3 faster F The new truck is bigger than the old one.
