Final answer:
Evidence to determine the size of the revolt can come from numerical data, collective actions like petitions, and the context of the historical period. Credibility of sources, such as Morris Rossabi, depends on their academic standing and biases. Motives and actions are understood through grievances, peaceful efforts, and philosophical underpinnings of the period.
Step-by-step explanation:
To determine if there is any evidence in the document that helps you measure the size of the revolt, one should consider various forms of evidence, including numerical data, described actions, and historical context. Numerical data, such as statistics, can provide concrete information about the scale, as illustrated by protestors' sign in Figure 12.1 referencing the Iraq War. The document's references to collective endeavors, like petitions for redress, imply a significant level of participation among colonists, indicating the size of the revolt. Additionally, reflecting on the time when the document was written, considering potential intimidation or distress faced by the author could also offer insights into the magnitude of the revolt.
Morris Rossabi's credibility as a source may be assessed by examining his expertise and potential biases. A reliable source typically is recognized by academic qualifications, peer-reviewed publications, and a reputation for accuracy within the academic community. Ascertaining such credentials can confirm or challenge the reliability of Morris Rossabi or any other author.
The motives behind the revolt and the individuals' actions involved can be deduced by analyzing their expressed grievances and recorded efforts to address these grievances peacefully. The background of the period, including events leading up to the revolt as in section 7.3.7 regarding the formal theory of revolt, enriches our understanding of the causes and size of the revolt by revealing the systemic and philosophical underpinnings of the colonial struggle.
