Which phrase from General Gage reveals bias against one of the groups involved in the Boston riots?

The phrase "Contrived by one Party" illustrates bias against a specific group involved in the Boston riots because it suggests that the events were not spontaneous reactions but rather planned or orchestrated actions by a particular faction. The use of the word "contrived" carries a negative connotation, implying deceitfulness or manipulation, which reflects an inherent distrust or prejudice against that group. This choice infers that the riots were not genuine expressions of discontent but rather the result of scheming by this one party, thereby delegitimizing the motivations and grievances of those involved. By framing the scenario in this way, General Gage reveals a bias that can influence perceptions of the rioters' motives and the legitimacy of their actions.
