Which verb means to turn something upside down or change the order of two things?

• A. Cross-section
• B. Double
• C. Invert
• D. Mechanism

Answer: (C)

Invert is the verb that exactly captures turning something upside down or reversing the order of elements. When you invert a container, you flip it, and when you invert the order of two items, you swap their positions. The other terms don’t fit this sense: cross-section is a noun describing a cut or view, not a flipping action; to double is about making two copies or doubling in size, not changing orientation or order; mechanism is a noun for a system of parts, not a verb for flipping.
