She may have reasoned in the dark that one way of the few there were would hide her and would leave no mark: black water, smooth above the weir like starry velvet in the night, though ruffled once, would soon appear the same as ever to the sight. which sentence best paraphrases these important closing lines of the poem? a) she decided to use the cover of night to run away and never be found again. b) she wished to be hidden in the dark somewhere near black water so no one would suddenly appear and see her. c) there were only a few people who were able to hide her in the dark night so that her husband would not find her. d) she thought there were only a few ways to commit suicide and leave no mark: after drowning herself in the water at night there would be no indication of it the next day.

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.
