Answer:
- by adding a statistic or a quotation.
Step-by-step explanation:
A counterclaim primarily aims to neglect the previous claim of the author and it is added with the aim to establish both the stands on the topic. The given rebuttal can be made impactful by 'addition of statistical data or quotation' as it will help nullify the counterclaim effectively and establish the validity and credibility of the author's actual claim which will appeal to readers' logic and make them believe in it. A strengthened rebuttal helps establish the author's objectivity and unbiasedness and validates why he favors that specific stand of the topic. Thus, it displays the author's claim to be fairer and justified.
