Fact: The ground is wet and there are dark clouds in the sky.
Observation: People are carrying umbrellas as they walk down the street.
Inference: It is likely that it has recently rained or is about to rain. This inference supports comprehension because it allows us to connect the observable elements (wet ground and dark clouds) to a possible conclusion about the weather conditions. By inferring that rain has occurred or is imminent, we can better understand the context of the scene and the actions of the people with umbrellas.
