Context: He told me he had dispatched a supervisor to intercept the train / conductor and that an incident report would be sent to RTD and to the ADA . I wrote RTD an e - mail later that night asking for a follow - up as to what was being done , and they said it was under investigation and they would get back to me in 10 - 14 days . I can understand a ticket officer asking me if he 's a service animal , I know he does n't look like the majority of those out there , and I know I do n't look disabled on the outside . That 's ok , and that 's legal .

Question: What 's a possible reason the writer does n't look disabled on the outside ?
Options:
0. Because an incident report would be sent to RTD and to the ADA .
1. Because he does need any special equipment to move around .
2. None of the above choices .
3. Because the writer wrote RTD an e - mail .
Answer: 1
