Context: His wife had been diagnosed with cancer and she needed to be in warmer climate . Someone gave him a second chance at life in Arizona and the program he was in required him to explain his presence in the community and ask people to rate him based on his acceptability to belong to this state . I was intrigued about this . Then he explained that he used to be a crack cocaine addict and he needed to prove to society that he deserves a second chance .

Question: Why would he have to prove to society that he needed a second chance ?
Options:
0. He was just exaggerating , people with crack cocaine addictions get by just fine in everyday life .
1. There was n't a real reason , it was just something he thought that he should do in order to fit in .
2. He had previously been addicted to a substance so he needed to show someone that he was capable .
3. He really did n't have to do that , it was more of a moral feeling that he had .
Answer: 2
