Question

How does the description of the skull Peterkin finds as "large, and smooth, and round" add to the poem's ideas about war?

Answer 1

C. It makes the skull sound like a toy ball, adding to the grandfathers casual view of the deaths caused by the battle. 
A is not correct because if it was unavoidable, he would have said something different to describe the forgotten skull.
B. Is not correct because if it brought sad memories, he would not have brought it up, sad memories hurt.
D is not correct because he would have described much worse if he wanted to frighten the children
