Answer:
A logical strategy for refuting counterclaims is using evidence.
In formal writing, it is important to refute counterclaims, which means to disprove the opposing argument(s) to your argumentative thesis. If you use informal language, this will not allow for flow and reasoning in your paper. Using fallacious reasoning would not be a positive way to refute counterclaims, because you want your paper to be filled with reputable facts and correct information. Finally, using emotions is frowned upon in formal and argumentative writing because your arguments or rebuttals should be based only on facts and logical evidence. To refute counterclaims, the best answer is thus to use evidence because this will support your rebuttal of the counterclaim and make any readers believe your claim.
