The distinction between real variables and nominal variables is known as inflation rate.
Explanation:
The inflation rate is what distinguishes real variables (such as increase or decrease in prices/price level of goods or services) from nominal variables (such as the quantity of available money: high or low money supply).

Answer:
The sentence that uses the word malleable correctly is;
The gold wedding band was malleable as it was shaped into a beautiful ring
Explanation:
Malleability is the property of metal to have their shape changed by means of hammering, pressing or rolling so as to form sheets without them breaking such that the metals assume a new shape by compression
An example of a malleable metal is gold, which can be hammered into a gold leaf
Malleability in metals is due to their ability to have their nuclear shifted while maintaining their bonds due to the ability for electrons to move freely such that they are replaced with ease
Therefore, the sentence that uses the word malleable correctly is the gold wedding band was malleable such that it was able to be shaped into a beautiful ring.
