Answer #1

Hamming could be the measure used because  the transactions would almost be similar

We would  want mainly to concentrate on the differences between the data points  instead of  their similarities.

because the differences which are minute can help us determine the proximity.

Suppose we have lots of similar purchases, if jaccard is used the entire product would be 1 which says it is dissimilar

So using hamming we can find the differences which are negligible and will find the proximity
