Read the passage. Which of the following is NOT appropriate to the overall tone of this passage?

The phrase "With an axe to grind" is not appropriate to the overall tone of the passage.

The passage discusses the plot and situation in Shakespeare's play Hamlet, focusing on the protagonist's encounter with his father's ghost and the task of seeking revenge. The tone of the passage is serious and dramatic, as it describes the ghost's revelation of murder, betrayal, and the weighty responsibility placed upon Hamlet.

However, the phrase "With an axe to grind" is an idiomatic expression that suggests having a personal agenda or a grudge against someone. It introduces a more casual and informal tone that doesn't align with the serious and dramatic tone of the rest of the passage.
