Question

1. why does juliet ask romeo not to swear his love’s allegiance by the moon?

Explanation:

Juliet believes the moon is an inconsistent, changing celestial body—it waxes and wanes, shifting its shape and brightness. She fears that a vow sworn by the moon would be as unstable and unreliable as the moon itself, so she does not want Romeo to base his love's pledge on something that is not constant.

Answer:

Juliet refuses Romeo's moon-sworn love because the moon is a variable, changing object (it waxes and wanes), and she worries a vow tied to it would be as unsteady and unreliable as the moon itself, rather than a constant, enduring promise of love.
