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.

the legal limit for the drivers who can drive after consuming any amount of alcohol is 21 years.

explanation:

on november 1, 1996, a "zero tolerance law" was put into effect in the new york state.

according to this zero tolerance law, for people under the age of 21 years, it was illegal to purchase and possess alcohol or to drive after consuming any amount of it.

also, the alcohol involvement rate for the drivers under the age of 21 was roughly twice that of elderly drivers.
