Question

modern us coins are made of copper and nickel alloys rather than pure gold. which characteristic does this primarily help maintain compared to using soft gold?

durability

portability

divisibility

uniformity

acceptability

Explanation:

Pure gold is soft, so coins made of it would wear out easily. Copper - nickel alloys are harder and more resistant to wear and tear. Durability refers to the ability of a material (or in this case, the coin) to withstand damage and last over time. Portability is about how easy it is to carry, divisibility about being able to split into parts, uniformity about being consistent, and acceptability about being recognized as valuable. Since the alloy makes the coin more resistant to damage, it helps maintain durability.

Answer:

A. Durability
