  1. True

  2. False


Correct Option: A
Explanation:

To solve this question, the user needs to have knowledge of the physical properties of gold and the concept of flattening materials.

The answer to this question is:

The Answer is: A (True)

Explanation:

Gold is a very ductile material, meaning that it can be flattened or stretched without breaking. In fact, gold is one of the most ductile metals known to man. A single ounce of gold (about the size of a matchbox) can be flattened into a sheet that is 300 square feet in size, or roughly the size of a tennis court. This property of gold is what makes it such a valuable material for jewelry and other decorative items. Therefore, the statement is true.
