I may be wrong but I don't think the question was actually ever answered.
In regards to situation/scenario questions posed at the interview (not SEARCH) there isn't a right or wrong answer as such.
These questions are often based on real life multiple emergency calls you may be asked to attend, all incidents happening at the same time at various distances from your current location and various degrees of information provided for each call.
A question could be for instance in which order would you attend those incidents? it is up to you to decide and explain your reasons behind your answers, expect to be challenged on one or more of those answers.
You don't need to have a police background in order to successfully pass really, it's more about common sense, see how flexible you are and justify your actions as well as carefully read the information you were provided.
Hope this answers the original question.
