Problem:Context: Atticus Finch is the middle-aged father of Jem and Scout Finch. He is a lawyer and was once known as "the deadliest shot in Maycomb County".

Student A:Higher-skilled players will typically play on "representative" or "travel" teams that will travel to play representative (rep) teams from other areas. These teams are classified by skill. Not all cities will have teams at all skill levels, depending on size and the popularity of hockey, however even small communities may field teams at multiple levels. (For example: Orillia, Ontario, with a population of 30,000, has four distinct skill divisions for 7-year-olds.) The classifications are typically not certified by any external organization, so there is speculation about what levels are truly better or stronger than others. AAA, AA, and A hockey are nationally recognized as competitive levels of organized hockey, with AAA being elite competition. The competitive level players generally engage in high levels of physical play from a young age. This physical play can lead to injuries and most often these are related to the head. Injuries have become more prevalent as physical play has increased in the sport.
