Which of the following statements about Grade A gage blocks is TRUE?

The statement that Grade A gage blocks are typically used for precision measurements is accurate because Grade A gage blocks are manufactured to very high accuracy standards. These blocks are used in a variety of precision measurement applications, such as calibrating measuring instruments or establishing precise lengths in manufacturing processes. Their high quality and minimal permissible error make them ideal for ensuring accuracy in tasks that demand precision.

In contrast, other grades of gage blocks, such as Grade B or C, are used for less critical applications where ultra-high precision is not as essential. Thus, Grade A gage blocks serve a critical role in environments where accuracy significantly impacts the quality of the final product or measurement.
