Context: They finally got the part installed and I hit the road at 4PM , with about a 6-hour drive ahead of me . Susan and the girls had arrived hours before and were shopping for house stuff . About four hours into my drive Susan called to say that the van had a flat , and AAA was flummoxed because we changed our membership to the Texas " club " but Susan 's mobile phone still had an Atlanta area code .

Question: Why were they so confused about the area code change ?
Options:
0. The membership was made for Texas but the phone number was from Georgia .
1. The tire was located in Atlanta when the people were in Texas .
2. They did n't know where they should dispatch and fix the tire .
3. They were n't sure if it was the real people calling .
Answer: 0
