What is the cumulative effect condition regarding copying for educational use?

The cumulative effect condition regarding copying for educational use is primarily concerned with limiting the amount of material that can be reproduced for a single class session. This principle is in place to ensure that the copying of materials does not significantly harm the market or potential income of the copyright holder. Under the Fair Use doctrine, educational institutions are often permitted to make limited copies for use in classes, with the understanding that these copies are intended for a specific educational activity and context.

In this case, stating that copies can only be made one time for a single class reinforces the idea that educational use should be limited and focused, rather than allowing for ongoing or repeated distribution of the same material across different classes or for various purposes. This approach safeguards the interests of copyright owners while still promoting access to educational resources for students and educators.

The other options do not accurately reflect the limitations and principles set forth by copyright law regarding educational use, particularly the focus on limiting the scope of copying to ensure fair use.
