What are dry measures primarily designed for?

Dry measures are primarily designed for the measurement of solids. This type of measurement involves containers that hold dry commodities such as grains, powders, and other bulk materials. The design of dry measures allows for accurate volume measurement of these solids, making them suitable for use in a variety of contexts, including cooking, agriculture, and commerce.

Options that focus solely on liquid measurement, volume measurement only, or measurement of gases do not adequately describe the primary function of dry measures. While they may pertain to other forms of measurement, they do not reflect the specific purpose and design of dry measuring containers, which are tailored to accurately handle and contain solid materials. This specialization is key in contexts where the physical properties of dry substances need to be quantified reliably.
