Answer:
The answer choice that most strongly suggests Fabiola's sense of loneliness on the flight to Detroit is B. The narrator describes the empty seat beside Fabiola.
Step-by-step explanation:
In the given answer choices:
A. Fabiola compares herself to a pebble. While this comparison may indicate a sense of smallness or insignificance, it does not necessarily imply loneliness.
B. The narrator describes the empty seat beside Fabiola. This description directly indicates a lack of company or someone to sit beside Fabiola, which can contribute to a feeling of loneliness.
C. Fabiola compares herself to the universe. This comparison may imply a sense of awe or contemplation, but it does not explicitly convey loneliness.
D. Fabiola curls up next to her mother. This action suggests physical closeness and comfort, but it does not necessarily indicate loneliness.
Therefore, the description of the empty seat beside Fabiola (choice B) is the strongest indication of her sense of loneliness on the flight to Detroit.
