Comprehension/ Passage
1. Orville and Wilbur Wright, the inventors of the first flying machine, had always had a compelling interest in aeronautics and mechanics. As young boys, they earned money by making and selling kites and mechanical toys. Later, they built a printing press and operated a bicycle-repair shop.

But most corals are greenish, brown, bluish or yellow. Coral reefs offer shelter and food to thousands of creatures. The warmer the climet, the greater the variety of species there is. In the tropics, it is easier to find, in one place, ten different species than ten specimens of the same species; and a coral reef provides ample proof of that rule. Living conditions are most favourable, so that many forms are able to develop and survive in their struggle for existance.
