General Gates's troops held their ground. Benedict Arnold, one of Gates's generals, argued for a counterattack that would smash the British force. Gates, outraged that Arnold would challenge his order, took away his command. But the rash Arnold saw a chance to strike a crucial blow. He galloped through the crossfire of both armies, inspiring his men. A bullet struck his leg, but he rode on, leading the final assault that shattered the British fortifications. If he had died of his wounds that day, Arnold would be remembered as one of the great heroes of the Revolutionary War. What evidence in the excerpt suggests that Benedict Arnold was a brave soldier?

Read the excerpt from the code book. without much hope of a theoretical breakthrough, cryptanalysts have been forced to look for a technological innovation. if there is no obvious way to reduce the number of steps required for factoring, then cryptanalysts need a technology that will perform these steps more quickly. silicon chips will continue to get faster as the years pass, doubling in speed roughly every eighteen months, but this is not enough to make a real impact on the speed of factoring—cryptanalysts require a technology that is billions of times faster than current computers. consequently, cryptanalysts are looking toward a radically new form of computer, the quantum computer. if scientists could build a quantum computer, it would be able to perform calculations with such enormous speed that it would make a modern supercomputer look like a broken abacus. the author’s purpose in this paragraph is to convince the readers to pursue a career in analysis. explain the need for faster technology in cryptanalysis. entertain with interesting stories about supercomputers. argue for more money to develop a quantum computer.
