Question 5

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.

people who study codes

Question 6

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.

Question 8

Which excerpt from "The Enigma Machine” supports the idea that Allied forces expected the Germans to complicate their coding system?

Revolt · Accepted Answer

After 1938, when the Germans introduced additional rotors and plugs to increase the number of possible combinations, Polish and British cryptologists had already developed alternative methods of recovering the daily keys.

Question 9

Which best describes the author’s viewpoint about the people who learned to decipher the Enigma in "The Enigma Machine”?

Revolt · Accepted Answer

They played a very significant role in helping Allied forces.

Question 10

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.

Revolt · Accepted Answer

For a long time, scholars from different places tried to figure out the meaning of hieroglyphs, but they mistakenly believed each hieroglyph was a symbol.
