Twain's experience as a Captain would have given him knowledge of the river that most authors wouldn't have. Having traveled the river, Twain was able to describe the banks, the islands, and the beauty from experience. Almost like a painting. His writing and experience leads the reader to be able to envision themselves in Twain's setting. That's an author's true gift~ to take the reader to places they've never been.
Sentence 4 hope this helps :P
Answer:
what passage are you referring to? It's not posted!
The correct answers are "Only a small fraction is securely encrypted; the remainder is poorly encrypted" and "Anybody can get their hands on more information".
It is true that not all of the internet traffic is protected. About 60% of this traffic is encrypted; the rest remains a work in progress. This puts uncovered information at the risk of getting collected by able computer security technicians.
With the increasing availability of tools to simulate firewall security breaches, free to download from the internet, anybody who takes the time to learn these practices is capable of compromising unencrypted information - or even encrypted, depending on their skill.
The other options are not to be considered supportive of the central idea since:
The quantity of internet users is irrelevant to the fact that whether the current amount of information is at risk or not. The precautions these users take when browsing the web however, are a more contributing fact to the idea.
Most people do not take adequate precautions when it comes to their privacy, evidence being that the amount of personal data submitted to social networks allows their administrators to take advantage of it, selling the information to advertisers and ensuring a multi-millionaire income.
