In an argumentative essay, where should the writer present the counterclaim?
as part of the introduction to the claim
immediately following the initial claim
after the supporting evidence for a reason
as part of the conclusion of the argument

The answer is C: after supporting evidence for a reason.

 An argumentative essay presents arguments of both sides equally balanced, or, sometimes, one side can be more forcefully presented than the other, which has the purpose of changing the reader's mind or actions. First, there is a premisse (claim) followed by evidence to support the claim, and then the counterclaim to refute earlier arguments and reinforce the writer's point.

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.
