Evaluating an Argument and Questioning: The Code Book Answers

Which kinds of evidence are included in the excerpt? Select 3 options.

To evaluate the effectiveness of an argument, the reader needs to assess whether the author’s reasons and evidence are:

Do I agree with what the author says in this text?Who assigned me to read this text?What details in the text are unclear to me?What other texts has this author written?

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.

To understand the main idea of an informational text, you should ask yourself

To improve understanding of an informational paragraph, which questions are best to ask? Select 5 options.What is this paragraph mostly about?Are there any unfamiliar words I need to learn?What is the author’s claim?How does the evidence relate to the claim?How long is this paragraph compared to the others?Is the evidence relevant to the claim?Should the author cut this paragraph from the text?

Read the quote from Zimmermann in The Code Book.A future government could inherit a technology infrastructure that's optimized for surveillance, where they can watch the movements of their political opposition, every financial transaction, every communication, every bit of e-mail, every phone call. Everything could be filtered and scanned and automatically recognized by voice recognition technology and transcribed. It's time for cryptography to step out of the shadows of spies and the military,
