Answer:
The literary craft used in the sentence "She fixed him with a look that burned in silence" is imagery.
Imagery is a literary device that uses descriptive language to create vivid mental images, sensations, and emotions in the reader's mind. In this sentence, the phrase "fixed him with a look that burned in silence" creates an image of a woman giving a powerful and intense look to a person. The phrase "burned in silence" adds to the intensity of the image, creating a sense that the look was so powerful that it was like a physical force.
By using imagery, the author is able to create a vivid and memorable picture in the reader's mind, which helps to convey the emotions and atmosphere of the scene.
