Final answer:
The literary device used in the quote is imagery, which creates vivid sensory experiences for the reader by using descriptive language.
Step-by-step explanation:
The literary device used in the quote “Never shall I forget that smoke. Never shall I forget the small faces of the children whose bodies I saw transformed into smoke under a silent sky” is imagery. This device involves using descriptive language to create vivid sensory experiences for the reader. It is intended to paint a picture in the reader’s mind, enabling them to see, feel, or understand the scene or emotion being described. Imagery is not just visual; it can also refer to tactile, olfactory, auditory, or gustatory sensations. The quote evokes a powerful visual and emotional response, painting a grim picture of a tragic event. It does not fit the definition of foreshadowing, as it is not hinting at future events. It is not an example of irony, which would imply a discrepancy between expectations and reality. While it does invoke certain ideas and emotions, the quote itself directly describes the scene without the use of symbols to represent something else, distinguishing it from symbolism which relies on symbols to imply a deeper meaning.
