Read the following passage and choose the correct answer.
Without the Nile River, the great civilization of ancient Egypt may never have existed. Until about nine thousand years ago, all of Egypt was under water. When the climate began to turn dry, tribes moved from North Africa to land near the river. Small villages appeared along the banks of the Nile. Each village had a chief who would battle other villages. Around 3300 BCE, these tribes came together to form the civilization of ancient Egypt.
One reason ancient Egypt was built around the Nile River was because its yearly flood made farming possible. The flood was so important that religious leaders would perform ceremonies that were believed to cause the river to rise and flood. The flood made the land very good for growing grains such as wheat and barley. Farmers began to plant these crops in November, right after the flood. Because of the Nile, $they$ were usually able to grow a lot of crops. If the grain was not used, it would be $stored$ for later use. Historians believe this is one reason that ancient Egypt became a powerful and wealthy nation.
The Nile also served as an important means of transportation. Ancient Egypt did not have the wheel, so there were no wagons or carts back then. However, ancient Egyptians learned to build boats so that when the Nile flooded they could use the river as a main road throughout Egypt. It is said that without the Nile, there would be no pyramids. This is because historians think that the huge stones were carried on the river by boat. This would explain why the pyramids sit close to the river on its west bank.
