Answer:
Writers use allusions to refer to people or elements that can contextualize the text and make it richer and more understandable.

The allusion is a figure of speech that allows an author to make references to other authors, people and works in his text. This guarantees a tintertextuality that, in addition to stylizing the text, allows contextualization, increases the meaning of the text and presents the knowledge and the amount of information the text presents. This figure of speech has a stylistic character and is very efficient and popular, and can be seen in several works.
Example: My father always supported my ideas and this gave me the strength to continue following my dreams, some did not come true, but "I did it in my way".
