Question

only a small fraction of the information flowing around the world is securely encrypted, and the remainder is poorly encrypted, or not encrypted at all. this is because the number of internet users is rapidly increasing, and yet few of these people take adequate precautions in terms of privacy. in turn, this means that national security organizations, law enforcers and anybody else with a curious mind can get their hands on more information than they can cope with. -the code book, simon singh which details support the central idea that information on the internet is not protected well enough? check all that apply. “only a small fraction... is securely encrypted” “the remainder is poorly encrypted” “the number of internet users” “people take adequate precautions in terms of privacy” “anybody... can get their hands on more information”

Explanation:

The central idea is about inadequate protection of Internet - information. Details that directly relate to poor encryption or easy access to information support this. "Only a small fraction... is securely encrypted" shows most is not well - protected. "The remainder is poorly encrypted" also indicates lack of protection. "Anybody... can get their hands on more information" implies lack of security. "The number of Internet users" is a cause, not a direct support of poor protection. "People take adequate precautions in terms of privacy" is contrary to the idea.

Answer:

"only a small fraction ... is securely encrypted", "the remainder is poorly encrypted", "anybody ... can get their hands on more information"
