The question is asking to select the group of numbers with the most obvious outlier that skews the average making the median a better choice to represent the numbers. Of the following:

1) 37, 38, 50, 55, 70

here the average and median are the same so this one can be eliminated

2) 0,50,55,60,10000

here the average is 2000 and the median is 55. The average is heavily skewed by including the value 10000

3) 0, 0, 0, 47, 50

here I would say not enough data but no obvious skew

So in the above more than the others the answer would be group 2
