Final answer:
Metaphors are often used in literature to express complex ideas such as a lack of sense of belonging, particularly in context to subjects like cultural revolution, apartheid, industrialization, and nationalism.
Step-by-step explanation:
Metaphors are a key literary device used by authors to draw comparisons and express complex ideas in a more relatable way. A student asked about metaphors that Trevor Noah uses to establish a lack of sense of belonging. In broader literature, subjects such as the cultural revolution, apartheid, and nationalism are topics ripe for the use of metaphors to communicate feelings of alienation or disconnection.
For example, during periods of industrialization, metaphorical language has been used to describe the alienation of workers from their labor, leading to a loss of a sense of self, as nothing ties the worker to her labor. Themes of nationalism are also criticized in some literature for how they can distract from economic struggles and foster exploitation within a 'nation'. Similarly, under apartheid, metaphors were often used to highlight the vast prejudices and systemic inequalities that left individuals or communities without a sense of belonging or identity within their own country.
