An example of a sentence that would require a reader to make an inference about what is happening could be:
"Despite the heavy rain, Sarah stood at the bus stop, her gaze fixed on the road, waiting for something that never came."
In this sentence, the reader must infer that Sarah is waiting for a bus, and possibly feels a sense of anticipation or disappointment due to the situation. No explicit details are provided about what she is waiting for, prompting the reader to deduce the context.
