  stop will be determined by the number \nof passengers who got on and off the bus
  throughout the journey.\n\nAt the first bus stop, 3 passengers got on the bus, and
  4 passengers got off. This means there were 10 - 4 = 6 \npassengers remaining on
  the bus.\n\nAt the second bus stop, 5 passengers got on the bus, and 3 passengers
  got off. Now there are 6 + 5 - 3 = 8 \npassengers on the bus.\n\nAt the final stop,
  all the remaining passengers will get off the bus. Therefore, 8 passengers will
