Read this excerpt from Al Gore's Nobel Prize acceptance speech:
Climate refugees have migrated into areas already
inhabited by people with different cultures, religions, and
traditions, increasing the potential for conflict. Stronger
storms in the Pacific and Atlantic have threatened whole
cities. Millions have been displaced by massive flooding in
South Asia, Mexico, and 18 countries in Africa. As
temperature extremes have increased, tens of thousands
have lost their lives. We are recklessly burning and clearing
our forests and driving more and more species into
extinction. The very web of life on which we depend is
being ripped and frayed.
Which statement best describes Gore's use of evidence to support his
argument?

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.
