Final answer:
The teenage girl in the scenario would likely be sentenced to a minimal one-year sentence in jail if she, and another involved suspect, chose to remain silent according to a scenario reminiscent of the Prisoner's Dilemma.
Step-by-step explanation:
The sentence for the teenage girl who hit Debbie could vary widely depending on the circumstances and the legal system in place. However, based on the provided information, it seems that if both suspects - in this hypothetical scenario, the teenage girl and another individual - chose to stay silent, they would likely receive a minimal one-year sentence. The reference to Table 6.1 suggests that the consequences of their actions are being evaluated in the context of a strategic decision, possibly alluding to the game-theoretical concept known as the Prisoner's Dilemma, a common element in criminal justice courses and law studies.
