which device is “i’m a window” an example of?
the narrator sees the reflection of another veteran looking at the memorial. the narrator says, “he’s lost his right arm / inside the stone.” “inside the stone” is a metaphor for.
done

Explanation:

For the first blank: "I'm a window" is a metaphor. A metaphor is a figure of speech that directly compares two unrelated things by stating one is the other. Here, the narrator compares themselves (or their perspective) to a window, so the device is a metaphor.
For the second blank: "Inside the stone" is a metaphor for the veteran's experience being a part of the memorial (or the veteran being remembered/immortalized in the stone of the memorial, or his loss being embedded in the memorial's structure). The memorial is likely a stone - based structure (like the Vietnam Veterans Memorial), and the phrase suggests his lost arm (and by extension his war experience/loss) is a part of that memorial's essence.

Answer:

First blank: Metaphor
Second blank: The veteran's experience (or loss) being a part of the memorial (or similar interpretation related to the memorial and the veteran's sacrifice/loss being embedded in it)
