Question

america has a deeply confused image of itself that is in perpetual tension. we are a nation that takes pride in our ethnic diversity, recognizing its importance in shaping our society and in adding richness to its existence. yet, we simultaneously insist that we can and must function and live in a race - and color - blind way that ignores these very differences that in other contexts we laud. - \a latina judges voice,\ sonia sotomayor
how do the underlined phrases affect the meaning and tone of this passage?
they show diversity.
they demand change.
they celebrate diversity.
they express a moral dilemma.

Explanation:

The underlined phrases "deeply confused image" and "perpetual tension" along with the contrast between taking pride in ethnic diversity and insisting on a race - and color - blind way that ignores differences show a conflict. A moral dilemma is a situation where there are conflicting moral principles. Here, the conflict is between valuing diversity (a moral good of inclusivity) and the supposed moral good of color - blindness (which may undermine the celebration of diversity). The other options: "They show diversity" is too simplistic as it doesn't capture the conflict; "They demand change" is not indicated as there's no call to action in the phrases; "They celebrate diversity" only focuses on one side of the contradiction.

Answer:

They express a moral dilemma.
