Question

Which phrase from “Meeting at Night” contains alliteration?
A. “the yellow half-moon large and low”
B. “the two hearts beating each to each”
C. “As I gain the cove”

Answer 1

A. “the yellow half-moon large and low

Answer 2

The grey sea and the long black land;
And the yellow half-moon large and low;

The poem opens with a description of the landscape: a "grey sea," "long black land," and a "half-moon" that is either rising or setting (it is "low" on the horizon).
There are no verbs in these first two lines, so we don't know what the land is doing; it is just there.
"Black land" and the presence of the moon inform us that it is nighttime (hence the title "Meeting at Night").
