Answer: Metaphor
.
Explanation:
This is a line from Martin Luther King Jr.'s open letter, known as <em>The Letter from Birmingham Jail</em>, in which he supports nonviolent resistance to racial discrimination.
King describes all the hardships that people face, and explains that for people who have never experienced them, it is easy to say that those who did need to wait patiently for their rights. One of these hardships is segregation, and King uses a metaphor in this line to emphasize it.
<em>A metaphor</em> is a figure of speech in which two objects/concepts that do not have much in common are compared, in order to explain an idea. There is no such thing as <em>"stinging darts of segregation"</em>, but King uses sharp darts to demonstrate the effect that racial discrimination has on people who experience it.
The right answer for the question that is being asked and shown above is that:
"To sail beyond the sunset, and the baths
Of all the western stars, until I die.
It may be that the gulfs will wash us down;
It may be we shall touch the Happy Isles,
<span>And see the great Achilles, whom we knew."</span>
The answer should be selective attention, but since that isn't a choice, selection is the best answer
