The correct answer is B. Evaluate the argument of each piece
Step-by-step explanation:
An editorial is a type of short text in which editorial staff presents their position towards a current situation or events by supporting it with arguments. Due to this, if you are asked to compare editorials the focus should be the position and arguments of editorials rather than the style or any other element in them. This implies an effective comparative essay of this kind should analyze the differences and similarities between the arguments and position presented including which editorial is more effective. Thus, an essay that effectively compares two editorials must evaluate the argument of each piece (Option B).
