Final answer:
Annette may realize someone is sick by observing symptoms, changes in behavior, or verbal hints from others, as commonly depicted in literary dialogues and character interactions.
Step-by-step explanation:
Annette may infer that something is wrong through visual cues, verbal expressions, or a change in someone's behavior, which might indicate that someone is sick or not feeling well. For example, if Steven or someone else has been showing symptoms of illness or has mentioned feeling unwell, such as having a headache, being homesick, or exhibiting bad behavior due to feeling under the weather, Annette might pick up on these clues. In literature, characters often reveal their physical or emotional states through dialogues or interactions with other characters, sometimes prompting concern from those around them.
