Final answer:
The social power of Claudio cannot be determined without specific context. Locke did consider the Glorious Revolution legitimate, the market revolution had substantial social and economic impacts, and Jefferson's economic pressure efforts were ultimately ineffective.
Step-by-step explanation:
The statement "Claudio is the most socially powerful person in the play" cannot be verified as true or false without knowing the specific play being referenced. If this question pertains to history, we could refer to a historical figure like Publius Clodius Pulcher, known as Clodius, and make similar observations regarding his power in the context of ancient Rome. However, without the necessary context of the play or literary work, it is not possible to determine the social power of the character named Claudio.
As for the other historical statements, according to most historical accounts, John Locke did view the Glorious Revolution as a legitimate correction of government when James II was removed from power, and the market revolution did indeed bring significant social and economic changes to the United States. Thomas Jefferson's efforts to use economic pressure through the Embargo Act of 1807, however, did not resolve tensions with Britain and France and is often considered unsuccessful.
