3) When finding and evaluating research; information from an unknown blog is acceptable. FALSE
4) Fair use allows students and teachers to use information without violating copyright laws if the information is used for a limited educational purpose. TRUE

Answer 1

I disagree with #2 -- as long as you pay attention to the references and external links at the bottom of a WP page and verify accuracy, WP articles can be quite good.

I think the word "acceptable" is the key there -- acceptable to whom?
