Final answer:
Marina Silva's tone is best described as critical, emphasizing the significant role of the federal government's actions. The traditionalistic political culture refers to the maintenance of the existing social order, and the term sovereignty describes a state's recognition of another state's autonomous power. So the correct option is B.
Step-by-step explanation:
Marina Silva's tone in the statement, “This is the first time it has happened thanks to the discourse and activities of the federal government,” can most appropriately be described as critical. The context of this statement is not provided in the question, but typically, if someone points out an occurrence for the first time due to government activities, there's an implication that they are spotlighting the role of the government as pivotal and noteworthy, often in a critical or evaluative way. Thus, this likely implies a recognition with potentially a hint of criticism of the government's action or inaction in a given context.
Regarding the question concerning the political culture where the government maintains the existing social order, the correct term would be traditionalistic. In a traditionalistic political culture, there is a maintenance of the status quo, and social and political relationships are characterized by a continuation of what has been historically established.
Regarding social media's impact on governance, the role of social media in organizing events and shaping public opinion has been significant. It has the power to influence politics by allowing information dissemination and organizing at unprecedented speeds, which can contribute to government misjudgment or swift social changes, often catching governments off guard.
In international relations, when a state recognizes another state's sovereignty, it is both exercising and bestowing power. Sovereignty acknowledgment implies respecting the autonomy and self-government of the other state, thereby highlighting a recognition of equal status in the international system.
