Input: Consider Input: Article: Many people have wondered what makes the oceans rise and fall on the word's beaches twice a day. Those tides are caused by the force of the Moon's gravity and the rotation of the Earth. Gravity acts on the center of any solid object. The Earth is mostly molten rock, but compared to the oceans, we can think of it as a solid object. As you know, the oceans are fluid and lie on the surface of the Earth. When the Moon is overhead, the oceans are four thousand miles closer to the Moon than the Earth's center is. Because the oceans are closer, the Moon pulls harder on the water than on the Earth. This stronger pull makes the water bunch up a little under the Moon, creating a high tide. At the same time, the oceans on the opposite side of the Earth are four thousand miles farther from the Moon than the Earth's center is. The Moon's pull on this water is weak. This water bunches up because it is "left behind"(making another high tide) as the Earth is pulled slightly towards the Moon. When the waters bunch up on these two sides of the Earth, they draw water away from the other sides of the Earth, which creates the low tides. As the Earth rotates, different parts of the land and oceans pass through the high-tide and low-tide zones. And that makes the waters on our coasts go up and down.
Answer: Moon's gravity or Earth rotation

Output: According to the passage, there would be no tides if there were no _ .

Input: Consider Input: Article: Even people who don't understand English can enjoy Chaplin's films because they are mostly silent. It isn't what he says that makes us laugh. It depends upon actions which mean the same thing to people all over the world. He is _ of the art - a kind of world language. As a young man, he and his brother traveled to America in a small company of actors. Chaplin was then invited to join a new company that was making film comedies. Very soon he had made dozens of short films for this company. And it was in his second film that he wore the clothes which made his reputation - black hat, tight coat, baggy trousers, huge shoes, moustache and walking stick. He intended simply to make people laugh. But the odd make-up made him look both comic and sad. By the time he was thirty, Chaplin was the greatest, best known and best loved comedian in the world. He received thousands of dollars for each film he made. He had formed his own manner of acting. He was welcomed by excited crowds wherever he went. But he worked very hard and had few close friends. Perhaps that is why the sad side of the little tramp began to show more clearly in the films he made. The little man began to want more than food and a roof over his head. He began to want love. In one of his most famous films "The Gold Rush" a girl plays tricks on the little man. Then she begins to feel sorry for him and treats him kindly. He mistakes her pity for love. The girl in "City Lights" is blind. She thinks he is the most wonderful man she has ever met. But then she recovers her sight and sees what a foolish figure he is. This sadness gives Chaplin's films a depth of human experience which few comedians can equal. After living in America for forty years he moved to Switzerland. There he died on Christmas Day 1977. He once described himself as a citizen of famous pictures that were made during the 1920s and 1930s, the time of the silent films. But, to many people all over the world Chaplin will always be the king of comedy.
