    ANSWER
     
    Distance allows us to define the clusters. Distance can be measured in many different ways: Euclidean distance, squared Euclidean distance, block distance, Minkowski measure, chi-squared distance, etc. Which one to use depends on the nature of the data and the clustering criterion.
