Which statement is correct regarding the cost of making copies?

The assertion that engineering copiers are cheaper than diazo machines highlights the differences in technology and functionality between these two types of equipment. Engineering copiers are generally designed for producing high-quality reproductions of engineering drawings, blueprints, and other detailed documents. Their advanced technology and capabilities, such as handling larger formats and providing greater resolution, often come at a higher cost.

Conversely, diazo machines, which predominantly use a chemical process for creating reproductions, tend to be less expensive. They are typically suited for simpler reproduction tasks and are often used for projects requiring less precision. The lower cost of diazo machines reflects their more limited functionality compared to engineering copiers.

In summary, the statement regarding the lower cost of engineering copiers in comparison to diazo machines is correct, as it recognizes the technological differences and resulting cost implications of each type of copier.
