Recall that impromptu was a satire of the chou leaders that critiqued their dealing with dangerous rulers. explain the necessity for the use of satire in this poem. why might the author not have felt free to voice his opinion about the chou leaders frankly?

The correct answer is - The writer prefers ROXXOR to the other bands that played.
Bias means that he loves something more than something else, and that he cannot be objective when it comes to that thing he loves. It is clear here that the author thinks the other bands were amateurs, but when it comes to ROXXOR, they were great in his own personal opinion, which is slightly biased.
