Read the following poem and answer the questions-

She walks in beauty, like the night

Of cloudless climes and starry skies;

And all that’s best of dark and bright

Meet in her aspect and her eyes;

Thus mellowed to that tender light

Which heaven to gaudy day denies.

One shade the more, one ray the less,

Had half impaired the nameless grace

Which waves in every raven tress,

Or softly lightens o’er her face;

Where thoughts serenely sweet express,

How pure, how dear their dwelling-place.
