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.
