Which of the following passages from the letter most strongly supports the answer to the previous question?
A. “And even if you were in some prison the walls of which let none of the sounds of the world come to your
senses-would you not then still have your childhood, that precious, kingly possession, that treasure-house of
memories? Turn your attention thither."
B. "But even then this inward searching which I ask of you will not have been in vain. Your life will in any case find
its own ways thence, and that they may be good, rich and wide I wish you more than I can say."
C. "It was a pleasure to me to find in your letter the name of Professor Horacek; I keep for that lovable and
learned man a great veneration and a gratitude that endures through the years."
D. "The verses which you kindly entrusted to me I am returning at the same time. And I thank you once more for
your great and sincere confidence, of which I have tried, through this honest answer given to the best of my
knowledge, to make myself a little worthier than, as a stranger, I really am."

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.
