Read the passage below carefully and then choose the correct answer.

He had a fever when he was in Spain,
And when the fit was on him, I did mark
How he did shake: 'tis true, this god did shake;
His coward lips did from their colour fly,
And that same eye whose bend doth awe the world
Did lose his luster: I did hear him groan:
Ay, and that tongue of his that bade the Romans
Mark him and write his speeches in their books,
Alas, it cried 'Give me some drink, Titinius,'
As a sick girl. Ye gods, it doth amaze me
A man of such a feeble temper should
So get the start of the majestic world
And bear the palm alone.
