Answer 2

Answer is C.  Internet is a vast field, full of information and knowledge, which are very helpful for studies and research. Some come from safe sources and other might need some precautions. When we read something that seems to be interesting or even truthful, but the people that wrote it don't identify themselves, it can indicate that some information is being hidden on purpose. Also, being anonymous, make people with no accountability.
