Answer: Although many still claim that evidence about year-round school and its link to higher achievement is inconclusive, studies consistently reveal that year-round students score higher on certain assessments than those students who attend schools with traditional nine-month calendars.

Any argumentative editorial should always maintain a respectful tone to convey a point positively and affirmatively, based on evidence rather than personal believes or opinions. A counterargument should not attack those who differ from our position but provide evidence to disprove their claims.
Phrases such as "these people need to open their eyes", "they would admit defeat if only they would do their research", and "these people need to study their facts" are baseless accusations of researchers not doing their jobs properly. The best way to make a counterclaim against the opposite idea would be to establish supporting evidence, which is accomplished with the phrase "studies consistently reveal that".
