a reference in a text to a well-known text, person, event, or thing. This is the right option. The author makes the decision to refer to these items generally in an indirect way. For example, you should not wait as Penelope. Get out and meet a new man!. Penelope is Odysseu's wife.
These are not correct options:
- words, events, or dialogue in a text that hint at a future plot development. This is called foreshadowing.
-a communication between characters that develops character or plot. This is characterization
- incidents placed in a text by the author to mislead or trick the reader: This is plot device.
