Answer:
8. C) a lonely island.
9. B) metaphor
10. D) a bad check or promissory note
Step-by-step explanation:
King compares the life of African Americans to a lonely island. This metaphor implies that African Americans live a life that is isolated and does not compare to that of their neighbours.
The phrases "manacles of segregation" and "chains of discrimination" are metaphors. They are not meant to be taken literally. Instead, these words are included in order to provide vividness and intensity to the text.
The metaphor of a bad check is intended to symbolize the fact that the American government promised African Americans that they were going to enjoy equality, but this has not happened yet.
