Answer:
B). When you find yourself agreeing with a counterclaim that is made by your opponent.
Step-by-step explanation:
An argumentative research essay exemplifies the genre that requires a student to investigate or research an idea extensively to gather, evaluate, and ensure a position. It includes evidence to back and substantiate the claims offered or proposed in the essay. As per the question, one should think of modifying his/her claim when they agree with the counterclaim offered by their opponent as if one doesn't modify his/her claim at this point then it may lead to embarrassment and disappointment. A good speaker is one who knows how to present and modify his claims to make the readers agree with the claims offered at the end. Thus, option B is the correct answer.
