Context: I called AAA and then my step - father and it just turned into a giant fiasco . My brother had to come pick me up and the car has to stay there overnight ( because the garage was closed for the day ) , so that means we have to get up early , so we can drive there and unlock the gate and see the car get towed away . Then , because the garage only does oil changes on Saturday and they 're closed on Sunday , the car will have to sit there until Monday , which means I do n't have a car for the rest of the weekend .

Question: What may have caused the car to sit there until Monday ?
Options:
0. My brother needed to use it .
1. None of the above choices .
2. My step - father , the mechanic , was n't available until Monday .
3. The mechanic was n't available until then .
Answer: 3
