What does it mean to raise trivial objections?

To raise trivial objections means to introduce minor or petty criticisms, often in a way that is seen as unnecessarily nitpicky or argumentative. The correct answer, "cavil," specifically refers to the act of making such trivial objections or criticisms, often over insignificant details. This term is drawn from legal contexts but also applies broadly to discussions and debates where individuals might challenge or dispute points that do not substantially affect the overall argument or situation.

The other choices do not convey this specific meaning: "contumacious" refers to someone who is rebellious or disobedient, particularly in the context of authority; "defalcate" means to misuse or embezzle funds; and "calumny" denotes making false statements about someone with the intent to harm their reputation. None of these terms align with the idea of making trivial objections.
