Final answer:
In Langston Hughes's poem, the second example of figurative language is the metaphor "Life for me ain't been no crystal stair," which illustrates the mother's challenging life journey.
Step-by-step explanation:
The second example of figurative language in Langston Hughes's poem Mother to Son is in the line "Life for me ain't been no crystal stair." This line is a metaphor because it compares life's hardships to a stairway that is not smooth and luxurious like crystal but is instead rough and difficult to ascend. It encapsulates the theme of the poem that the mother's journey through life has been challenging. This is an example of figurative language because it uses imagery to make an abstract concept (life's challenges) more concrete and relatable through the comparison to a physically challenging and imperfect stairway.
