Final answer:
The Ghost of Christmas Present teaches Scrooge about empathy and the consequences of his actions on Tiny Tim, prompting Scrooge's transformation in 'A Christmas Carol'.
Step-by-step explanation:
When Scrooge shows concern for Tiny Tim, the Ghost of Christmas Present reveals future events that hi_nge on Scrooge's actions and attitudes. The spirit's role is to teach Scrooge about empathy and the impact of his miserliness on others, particularly on Tiny Tim, who is in frail health.
The ghost uses these visions to prompt a transformation in Scrooge, urging him to change his ways and thus potentially alter the outcomes for characters like Tiny Tim. Charles Dickens uses these interactions in his novel 'A Christmas Carol' to illustrate themes of compassion and redemption.
