Dear Sir,

     I have to travel every day from SoUk Road to the Airport. Two buses travel along this route: the number

49 and the number 16. However, by the time the number 16 bus reaches SoUk Road, it is always full, so it

is of no use for me. This leaves the number 49 which sometimes has empty seats on it.

     The timetable states that there are buses from SoUk Road to the Airport every ten minutes. If this is so,

why do I have to wait half an hour for a bus nearly every day? The instructions state that if there are empty

seats on a bus, the bus must stop at every stop where people are waiting. Why is it that half-empty buses go

straight past me when I am standing at the bus stop?

     The instructions state that no bus may carry more than 40 seated passengers and 20 standing passengers.

Yesterday, I was first to get off the bus when it reached the Airport. I counted the other passengers as they

got off. There were 129 of them.

     Clearly printed on the back of every bus is a sign that says "Maximum speed: 50 m.p.h." The distance

from SoUk Road to the Airport is 10 miles. Saturday morning a 49 bus traveled the distance in ten minutes,

at an average speed of 60 m.p.h. At times it must have done at least 80 or even 90 m.p.h. It is obvious that

our bus companies have no respect for the instructions nor consideration for their passengers. Can nothing

be done about this?

1. The writer prefers to take Bus No.49 because it _____. [ ]

A. stops at every stop

B. has more seats on it

C. travels faster

D. is not always full

2. According to the timetable, a 49 bus should travel through its route _____. [ ]

A. every ten minutes

B. in less than ten minutes

C. in more than twelve minutes

D. in half an hour

3. The writer is not satisfied with the bus company because _____. [ ]

A. buses are too crowded

B. bus drivers often go straight past without stopping

C. too few buses are traveling along this route

D. bus services are poor
