Read the passage below and answer the question that follows.
Romeo: [TO JULIET] If I profane with my unworthiest hand
This holy shrine, the gentle fine is this:
My lips, two blushing pilgrims, ready stand
To smooth that rough touch with a tender kiss.
Juliet: Good pilgrim, you do wrong your hand too much,
Which mannerly devotion shows in this;
For saints have hands that pilgrims' hands do touch,
And palm to palm is holy palmers' kiss.
Romeo: Have not saints lips, and holy palmers too?
Juliet: Ay, pilgrim, lips that they must use in prayer.
Romeo: O, then, dear saint, let lips do what hands do;
They pray, grant thou, lest faith turn to despair.
Juliet: Saints do not move, though grant for prayers' sake.
Romeo: Then move not, while my prayer's effect I take.
To what does Romeo compare Juliet?
A pair of lips
A shrine
A prayer
A pair of hands
