3. In the context of the passage, the first paragraph serves primarily to

Answer: B

Explanation:

The first paragraph serves primarily to highlight significant differences between two theories of justice in terms of their relevance for addressing certain inequities.

The first paragraph emphasizes the contrasting theories of justice proposed by John Rawls and Martha Nussbaum, specifically how each theorist approaches the evaluation of social position and the distribution of benefits and burdens.

A) outline in brief the passage author's argument regarding certain inequities and theories of justice

While the paragraph does mention inequities and theories of justice, it does not merely outline the author's argument. Instead, it focuses specifically on the differences between Rawls and Nussbaum's theories, which goes beyond a simple outline of the argument.

B) highlight significant differences between two theories of justice in terms of their relevance for addressing certain inequities

This option is correct because the paragraph explicitly contrasts Rawls' focus on primary goods with Nussbaum's emphasis on capabilities. It underscores how these differing perspectives on justice are pertinent to understanding and addressing the inequities that arise from economic and ecological interactions.

C) anticipate challenges to the conclusion reached at the end of the second paragraph

The first paragraph does not discuss or anticipate any challenges to conclusions found later in the passage. It strictly presents the foundational ideas of two theorists without engaging in a critique or anticipation of counterarguments.

D) raise questions about how effectively an existing theory of justice has addressed certain inequities

The paragraph does not raise questions regarding the effectiveness of either theory in addressing inequities. Instead, it serves to delineate the key differences between the theories rather than questioning their efficacy.

E) respond to opposing views that call into question the passage author's main conclusion

There are no opposing views presented in the first paragraph, nor does it serve as a response to any critiques. It focuses solely on the theoretical differences between Rawls and Nussbaum without addressing counterarguments.

Conclusion

Option B is definitively correct as it accurately captures the essence of the first paragraph, which revolves around contrasting two theories of justice and their implications for addressing inequities. Other options either misinterpret the content or fail to align with the primary focus of the paragraph, which is the comparison of Rawls' and Nussbaum's approaches to justice.
