how does the first paragraph of the dark game best support the central idea that the civil war was a long war? it shares the detail that the war lasted four years. it states what people believed about the war at the time. it tells how many soldiers actually died in the war. it gives an example of a battle that lasted almost two days.
Answer
Brief Explanations:
The length of the war is directly shown by stating it lasted four years. Other options do not directly relate to the length of the war. Stating people's beliefs, soldier - death numbers, or the length of a single battle do not as clearly support the idea that the Civil War was long as stating its total duration.
Answer:
It shares the detail that the war lasted four years.
