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, and step into the sunshine and be embraced by the rest of us. Which question does this paragraph answer?
Answer
A
Who made encryption based on Zimmermann’s work?
B
How does Zimmermann’s encryption work?
C
What kind of encryption did Zimmermann invent?
D
Why does Zimmermann think encryption is important?
Explanation
Zimmermann warns that a government could use surveillance technology to monitor people’s movements, finances, and communications. He argues that cryptography should be used by ordinary people, too, to protect against that surveillance. So the paragraph explains why he thinks encryption is important; it does not describe how his encryption works or what kind he invented.
