Sean Hasn't Always Been on the Wrong Side of the Law;

Sean hasn't always been on the wrong side of the law; he grew up in a two-parent household and was involved with his church and the community garden that his dad loved. When his dad was arrested and sent to prison for growing copious amounts of marijuana, everything changed. When his father was sentenced, his mom left him with his grandma and she hasn't been seen in 2 years. Sean has had many chances to reform his behavior in the juvenile system, and his grandmother has tried to get him counseling and a mentor. Despite his young age of 16, Sean has just been sentenced as an adult in a shooting rampage that killed one and wounded four.  
-Sean has recently been handpicked by the warden along with several other inmates to leave the prison and work for a company that is going to replace the roofs of all of the correctional institutions in the state. The origin of this type of work or arrangement can be found in:​

A) indentured servants.
B) the ticket of leave.
C) the contract system.
D) the convict lease.
