Read the poem.
i wandered lonely as a cloud
by william wordsworth
i wandered lonely as a cloud
that floats on high o’er vales and hills,
when all at once i saw a crowd,
a host, of golden daffodils;
beside the lake, beneath the trees,
fluttering and dancing in the breeze.
continuous as the stars that shine
and twinkle on the milky way,
they stretched in never-ending line
along the margin of a bay:
ten thousand saw i at a glance,
tossing their heads in sprightly dance.
the waves beside them danced; but they
out-did the sparkling waves in glee:
a poet could not but be gay,
in such a jocund company:
i gazed—and gazed—but little thought
what wealth the show to me had brought:
for oft, when on my couch i lie
in vacant or in pensive mood,
they flash upon that inward eye
which is the bliss of solitude;
and then my heart with pleasure fills,
and dances with the daffodils.
how does the speaker’s stating that his “heart with pleasure fills, / and dances with the daffodils” affect the tone of the poem?
it works to lessen the poem's mournful tone.

Wordsworth was a lover, admirer, and worshiper of nature. His poems echo the positivity, serenity, and beauty displayed through nature. The poem "I Wandered Lonely as a Cloud" too exemplifies just another compliment and admiration to nature. He demonstrates that nature acts as a soothing force that adds pleasure and joy. The lines “heart with pleasure fills, / And dances with the daffodils” personifies daffodils to symbolize the excitement and pleasure offered by nature that aids to escape solitude. The 'pensive' mood of Wordsworth sets a positive and vital tone to the poem juxtaposing the beginning that describes 'loneliness' and 'solitude'. Thus, these lines shift the tone and mood from negative and pessimistic to positive and optimistic through the beauty spread around by daffodils.

alliteration is the repetition of the same or similar consonants. having that in mind, i would say that the correct answer is: so shows a snowy dove trooping with crows.

as for symbolic actions, the narrator's tearing down the wallpaper in an attempt to find the "woman" in the wallpaper represents her struggle to retain or regain her sanity.   the wallpaper has been part of her confinement and by her tearing it down, she is freeing herself from that confinement.
