  question: If you are driving the bus, and bus initially has 10 passengers. At first
    bus stop 4 passenger gets off the bus and 3 get on to the bus. At second bus stop,
    3 passenger get off the bus and 5 get on the bus. Now bus reached to it's final
    stop. Answer the following questions, Who is driving the bus and how many total
    passenger will get off from the bus at final stop?
output: "Based on the information provided, the bus has 10 passengers initially. At
  the first bus stop, 4 passengers get off the bus, and 3 get on. This means that
  the bus now has 10 - 4 + 3 = 7 passengers. At the second bus stop, 3 \npassengers
  get off the bus, and 5 get on. Therefore, the bus now has 7 - 3 + 5 = 9 passengers.
  Since no other passengers get on or off the bus before it reaches its final stop,
  9 passengers will get off the bus at the final \nstop."
