The correct answers to this question are A) internet is a 24-hour operation and B) internet anonymity makes it difficult to track the sources of leaks.
It's not easy for an oppressive government to enforce a policy of digital censorship because the internet is a 24-hour operation and internet anonymity makes it difficult to track the sources of leaks.
Some oppressive governments have tried to censor the use of the internet in their countries. Others, as in the case of China, have shut down the internet. It is not an easy task because hackers have many resources to get and transmit information, stat in anonymity, and causing damage in government systems if they want. A 24-hour monitoring operation is difficult and costs money and resources, so censoring the internet is a difficult task. The other options of the question were C) the internet's design reads blockage as damages and self corrects and D) the information on government websites is too confusing to read.
