Final answer:
The correct answer is that the ladies show concern for black people halfway around the world but lack sympathy for those in their own town.
Step-by-step explanation:
The contrast in the ladies' concern for black people is that they are greatly concerned for black people halfway around the world but have no sympathy for black people in their own town. This is highlighted by Mrs. Merriweather's emotional response to the plight of the Mrunas, which is in stark contradiction to her indifference toward the suffering of blacks in Maycomb. The correct answer reflecting this hypocrisy is option 1: They are greatly concerned for black people halfway around the world but have no sympathy for black people in their own town.
