Answer:
d. by moving and refuting the counterclaim at the end
Step-by-step explanation:
According to the given draft paragraph from an argumentative essay, the narrator talks about the effect of the World War and tries to justify the use of the hydrogen bomb on Japan which led to their unconditional surrender by saying that it helped end the war quickly and save more lives.
However, at the end, he just says that the effects of the radiation were still there, without any preamble or prior claim
The author should revise the paragraph by moving and refuting the counterclaim at the end. This is because, they are not a suitable conclusion to the draft paragraph.
