The first true piece of sports equipment that man invented was the ball.
In ancient Egypt, as everywhere, pitching stones was a favorite children’s game. But a badly thrown rock could hurt a child. Looking for something less dangerous to throw, the Egyptians made what were probably the first balls.
 

At first, balls were made of grass or leaves held together by vines. Later they were made of piece of animal skin sewed together and stuffed with feathers or hay.
Even though the Egyptians were warlike, they found time for peaceful games. Before long they had developed a number of ball games, each with its own set of roles. Perhaps they played ball more for instruction than for fun. Ball playing was thought of mainly as a way to teach young men the speed and skill they would need for war.

The ball was probably invented because （）

A:throwing stones often caused injuries B:throwing stones was not fun C:games with stones did not have rules D:rocks were too heavy to throw

Passage Four 4
There was once a man who spent all his time in his glasshouse. Flowers was his name, and flowers were his main joy in life. He grew flowers of every color under the sun. He grew these flowers in order to enter them for competition. His greatest hope in life was to grow a rose of an entirely new color that would win him the silver cup for the Rose of the Year.
Mr. Flowers’ glasshouse was close to a public path, which was always used by children walking to and from school. Boys were often attracted to throw a stone or two at his glasshouse. So Mr. Flowers did his best to be in or close by his glasshouse at the beginning and end of the school day.
However, it was not convenient or possible to be on guard all the time. Mr. Flowers had tried in many ways to prevent harm to his glass; but nothing that he had done had been successful.
Then, just as he was giving up hope of ever winning the battle, and of growing the Rose of the Year, he had a truly wonderful idea. He put up a large notice made of good, strong wood, some metres away from the glasshouse, where it could be’ clearly seen from the path. He had painted on the board the words: DO NOT THROW STONES AT THIS NOTICE. After this, Mr. Flowers had no further trouble. The boys were much more attracted to throw stones at the notice than at the glasshouse.

He put up a large notice made of good strong wood in order （）

A:to tell the children not to throw stones at the notice B:to warn the boys not to throw stones C:to attract the boys to throw stones at the notice D:to warn them whoever threw stones would be punished
