Which excerpt from act I of Shakespeare’s Twelfth Night informs the audience that Olivia has gone into a self-imposed seclusion? DUKE: Why, so I do, the noblest that I have:
O, when mine eyes did see Olivia first,
Methought she purg'd the air of pestilence;
That instant was I turn'd into a hart;
And my desires, like fell and cruel hounds,
E'er since pursue me.—How now! what news from her?
(Twelfth Night, act I, scene I)

CAPTAIN: A virtuous maid, the daughter of a count
That died some twelvemonth since; then leaving her
In the protection of his son, her brother,
Who shortly also died; for whose dear love,
They say, she hath abjured the company
And sight of men.
(Twelfth Night, act I, scene II)

DUKE: How will she love when the rich golden shaft
Hath kill'd the flock of all affections else
That live in her; when liver, brain, and heart,
These sovereign thrones, are all supplied and fill'd,—
Her sweet perfections,—with one self king!—
(Twelfth Night, act I, Scene I)
