Answer:
a) Random sampling you select the members from a list, without looking at any characteristic. Since you look at an characteristic here(the last name, listed in alphabetical order), it is not a valid random sampling method.
b) There are various strategies of random sampling.
One of them is the systematic, in which you take each kth member.
In this example, we could select each 500/20 = 25th member, which would be an example of systematic random sampling
