if your roommates co-sign your apartment lease, they are
a. equally responsible for honoring its terms.
b. smarter than you thought they were.
c. not responsible for any damage that may occur.
d. equally responsible for paying moving expenses.

The answer to this question is a because co-sign means to share responsibility. This definition eliminates both options b and c. The reason that it is a is because you are co-signing a lease for the apartment. The apartment lease has absolutely nothing to do with paying for moving expenses, because the lease applies only to the building itself, not your means of transportation to get there.

explanation:

the silver bells of the sleds are merry and keep time in the winter nights while the sky twinkles happily. the golden bells of weddings are delightful in their peaceful happiness, foretelling a rapturous future. meanwhile, the brazen alarm bells scream frightfully in the night, with a discordant and desperate sound. in their clamor, these bells convey terror, horror, and anger. finally, the iron bells are solemn and melancholy, while those in the church steeple are like ghouls who feel happiness. the king of the ghouls, who rings the bells, cheerfully keeps time with the moaning and groaning bells.
