Read the passage and choose the best answer.

Out in the Pacific Ocean, 3,700 kilometers from Los Angeles, are the islands of Hawaii, the fiftieth state of the United States, with its area of 16,700 square kilometers.

The first Hawaiians arrived from other Pacific islands sometime around 100 AD. Then in 1778, Captain Cook visited Hawaii. He put the islands on his maps of the Pacific Ocean. Then more ships knew Hawaii and began stopping there for supplies.In 1820, a small group of people from the eastern United States came to teach the Hawaiian people about Christianity. They started farms to grow sugar cane and pineapples. Because there were not enough people to do all the farm work, farm owners brought in Asians - Chinese, Japanese, and Filipinos. Later Koreans, Portuguese, and Puerto Ricans also came. More people came from the US mainland and from other Pacific islands, and Hawaii became an island with traditions from several countries. People from the various nation groups have married each other, so today the groups are partly mixed.Hawaiians are very friendly and always welcome visitors. They celebrate traditional Chinese, Japanese, and Filipino holidays as well as holidays from The United states. Hawaii is known as the Aloha State. “Aloha” mean “hello”, “goodbye”, and “I love you” in Hawaiian.
