explains the stereotypical plot of a non-Hispanic merchant seeking to marry an elite Californiana based on economics: these women had property and inheritance rights equal to men. Novelists based their plots on the women's real-life economic power, which resulted in men's wishing to build economic alliances with them. Supporting this explanation requires supporting these economic ideas in some way.
A. The profitability of non-Hispanic traders' business is not an issue in
explanation; thus the change described has no significant relevance to that explanation.
B. The lack of the type of documentation described, rather than providing support for
explanation, signifies a deficit in documentary support for that explanation.
C. Correct. If elite Californianas did in fact own valuable properties,
economic explanation gains force. The women did have the real economic significance upon which
suggests the novelists drew.
D. If it were true that some non-Hispanic women controlled property in this way,
explanation of Californianas' uniqueness would be somewhat undermined.
E. If most of the property in nineteenth-century territorial California was controlled by Hispanic men, that suggests that Californianas were less likely to possess the kind of economic power described in
argument.
The correct answer is C.
