How does this excerpt develop the central idea that Elizabeth Van Lew helped expand the role of women in society? Choose two answers.
Read Melissa’s thesis statement.Both The Dark Game and The Code Book explain the importance of codebreaking.
Read the excerpt from The Code Book.Just as Whit Diffie predicted in the early 1970s, we are now entering the Information Age, a postindustrial era in which information is the most valuable commodity. The exchange of digital information has become an integral part of our society. Already, tens of millions of e-mails are sent each day, and electronic mail will soon become more popular than conventional mail. The Internet, still in its infancy, has provided the infrastructure for the digital marketplace, and e-commerce is thriving. Money is flowing through cyberspace, and it is estimated that every day half the world's Gross Domestic Product travels through the Society for Worldwide Interbank Financial Telecommunications network. In the future, democracies that favor referenda will begin to have on-line voting, and governments will use the Internet to help administer their countries, offering facilities such as on-line tax declarations.
Jac is reading this paragraph from The Code Book.Mathematicians have been studying factoring for centuries, and modern factoring techniques are not significantly better than ancient techniques. Indeed, it could be that the laws of mathematics forbid the existence of a significant shortcut for factoring.

Which best describes the author’s viewpoint about the people who learned to decipher the Enigma in "The Enigma Machine”?
Which excerpt from "The Enigma Machine” supports the idea that Allied forces expected the Germans to complicate their coding system?
Read the excerpt from "The Enigma Machine.”At Bletchley Park, the main site in Britain where Enigma codes were deciphered, six thousand messages were decoded every day by a staff of ten thousand men and women. Many of the messages were inconsequential, but more than a few were critical to the outcome of the war.
Read the excerpt from "The Enigma Machine.”Cryptologists looked for cribs, which are repeated expressions in messages. Sloppy operators would repeat phrases like "nothing to report" or "weather forecast" (Wettervorhersage), which served as clues. If there were no cribs to be found, the British would send out false information about, say, British mines planted in a given area. The Germans might then send messages with the name of that area, which would provide clues about deciphering that code.
If someone were to describe "The Rosetta Stone” to a friend, he or she would most likely compare it to
Read the excerpt from "The Rosetta Stone.”Egyptian scripts were replaced with Coptic, which included six demotic characters. In the ninth century, Arab scholar Abu Bakr Ahmad Ibn-Wahshiyah was able to partly decipher the hieroglyphs by comparing them to Coptic. But in the eleventh century, it too was replaced, by Arabic. The link was once again severed. For centuries, Western scholars tried to decipher the hieroglyphs, with little success. They were working under a false hypothesis, that the hieroglyphs were pictograms, with each symbol representing an object or an idea.
Read the excerpt from The Code Book.By this stage, sending a PGP encrypted message is becoming quite complicated. The IDEA cipher is being used to encrypt the message, RSA is being used to encrypt the IDEA key, and another stage of encryption has to be incorporated if a digital signature is required. However, Zimmermann developed his product in such a way that it would do everything automatically, so that Alice and Bob would not have to worry about the mathematics. To send a message to Bob, Alice would simply write her e-mail and select the PGP option from a menu on her computer screen. Next she would type in Bob's name, then PGP would find Bob's public key and automatically perform all the encryption. At the same time PGP would do the necessary jiggery-pokery required to digitally sign the message. Upon receiving the encrypted message, Bob would select the PGP option, and PGP would decrypt the message and verify the author. Nothing in PGP was original—Diffie and Hellman had already thought of digital signatures and other cryptographers had used a combination of symmetric and asymmetric ciphers to speed up encryption—but Zimmermann was the first to put everything together in one easy-to-use encryption product, which was efficient enough to run on a moderately sized personal computer.
Which excerpt from "The Enigma Machine” supports the claim that German soldiers accidentally helped the Allies figure out the Enigma codes?
Which evidence from "The Rosetta Stone” supports the claim that Thomas Young played a key role in helping to decipher the hieroglyphs on the Rosetta Stone?
