Hello there! A biased statement is where they show their favor in one side, and not give out the full story. It's basically an opinion. D is not a biased statement and neither is C, because those things don't show favortism or unfairness to one side. B sounds like an informed opinion, but it isn't the best answer for this question. A definitely takes the cake as the more biased statement, especially with them saying that reduced library hours wouldn't be convenient for them. It only shows one side of a situation and not the other. That statement is definitely biased. The answer is A.
The correct answer is B. The first sentence refers to a general proposition - <em>all combative sports should be strictly monitored</em> - and then it specifies that the Ultimate Fighting Championship (UFC) should fall into a category to be <em>monitored and regulated</em>.
