Read the following paragraph and choose the best topic sentence from the four options that follow.
Many people begin their day by waiting for a bus or train. Then they may spend a few minutes waiting for an elevator to get to their offices. Moreover, the elevator may then stop at twenty floors, averaging a wait of twenty seconds each. After work, there’s another wait for both an elevator and a bus or train. Most of us also spend a great deal of time waiting in the dentist's office, in line for tickets or fast food, and on the road in barely moving traffic.
