The document discusses how readers construct meaning from text when information is not clearly stated. It explains that readers must think about the writer's intended meaning and how they process sentences to infer deeper understanding. An example is provided where reading that "The Senator admitted owning the gun that killed his wife" allows readers to infer that the Senator was married, his wife is now dead, there was a gun involved, and the admission suggests the Senator's gun caused his wife's death. The document stresses the importance of inference and drawing conclusions to fully comprehend a passage.
