I'm going to go with the following: A national survey company picks one phone number from each area code in America to call and ask for an opinion on current political issues.
The reason I went with this option is because in statistic terms people are chosen from a larger group making them a subset. The individuals are being chosen randomly but yet the individuals all have the same likelihood of being chosen as anyone in the subset group.
Hopefully this helps and makes sense.
