  1. aSince the exact value cannot be known from the information provided, any value lower than given in the package leaflet including no response would be accepted. The frequency given in the package leaflet or higher would definitely be wrong
  2. bExact data lost due to technical problems, but the value was confirmed independently by two other lecturers
  3. cPossible answers: Since the exact value cannot be known from the information provided, any value except “none” and “more than 10” including no response would be accepted
