Task: Question Answering
Input (English): I have never had to ride a public bus until 4 years ago when I had no other transportation and was forced to take a public bus anywhere I needed to go . The first thing I had to do was find a bus schedule and learn how to read the time and places to catch the bus and how to make any needed transfers . This was a little hard to do but once I figured it out it was OK as long as I always kept a schedule with me . I mostly took the bus to work and I only had to worry about catching one bus on the street I lived on and I did not have to sorry about any transfers . The bus ride cost me $ 1.25 and transfers where an additional 50 cents . Many people rode the bus and I meet several nice people on the bus . The bus drivers were always nice and I became friends with several of them . The bus only came once an hour and I had to make sure I did not miss it if I was going to work because then I would be late for work . The bus always made a stop at the main depot in order to pick up more people . There was usually about a 20 minute wait so the driver could have break in the late afternoon . I did not like having to take the bus but it served my purpose for a while and I was thankful to have the bus available . 
Question: Who drove the bus?
Output (English): The bus drivers
