It is rare that there is just one way to respond to a scenario or situation, so do not consider that the responses you have to the above scenario will be judged as right or wrong. Share your scenario with a work colleague or friend and ask them to tell you whether they think you have responded appropriately. Ask them to challenge your response if necessary. You do not need to submit this task for assessment unless asked to do so by your assessor.
