In this excerpt from "the lady of shalott" by alfred, lord tennyson, which synecdoche denotes confinement?
willows whiten, aspens shiver.
a. the sunbeam showers break and quiver
in the stream that runneth ever
b. by the island in the river
flowing down to camelot.
c. four gray walls, and four gray towers
overlook a space of flowers,
and the silent isle imbowers
the lady of shalott.
underneath the bearded barley,
d. the reaper, reaping late and early,
hears her ever chanting cheerly,
like an angel, singing clearly,
o'er the stream of camelot.
e. piling the sheaves in furrows airy,
beneath the moon, the reaper weary
listening whispers, ' 'tis the fairy,
lady of shalott.'
