The root meter means

The root meter means

• A. Lead
• B. Water
• C. Hand, By Hand
• D. Measure

Answer: (D)

The idea being tested is recognizing a root that signals measurement. The root meter comes from Greek metron, meaning measure, and it appears in words for instruments or actions that measure something. That’s why it points to “Measure” as the meaning. You can see it in many terms like thermometer, speedometer, or odometer—each is about measuring or measuring devices. Lead, water, and hand-by-hand are tied to other roots and concepts (lead relates to plumbum, water to hydro/aqa, and manual or palm for hand), so they don’t convey the sense of measuring.
