Step-by-step explanation:
The type of conflict most strongly supported by the details in the narrative poem "Out, Out" by Robert Frost is Character vs. technology. The poem describes the tragic story of a boy who is injured by a buzz saw, resulting in the loss of his hand and ultimately his life. This situation illustrates a conflict between the boy, as he performs his work, and the technology of the saw that causes his injury. Despite the presence of other people in the poem, the central struggle revolves around the boy's interaction with the saw, a piece of technology, and its dire consequences.
