Question

read the excerpt from \mending wall.\ we keep the wall between us as we go. to each the boulders that have fallen to each. and some are loaves and some so nearly balls we have to use a spell to make them balance: \stay where you are until our backs are turned!\ we wear our fingers rough with handling them. oh, just another kind of out - door game, one on a side. it comes to little more: there where it is we do not need the wall: he is all pine and i am apple orchard. what does the line \and some are loaves and some so nearly balls\ refer to? the rocks that make the wall; the lunch that the speaker shares; a game that the neighbor plays; toys that they find while working

Explanation:

The excerpt is from a poem about mending a wall. The line "And some are loaves and some so nearly balls" is in the context of handling boulders (from "To each the boulders that have fallen to each") to repair the wall. The shapes of the boulders are being described—some like loaves, some nearly round (balls). The other options (lunch, a game, toys) don't fit the context of mending a wall with boulders.

Answer:

the rocks that make the wall
