Why are case study resources not included in the PDF of the practice exam?

The correct answer indicates that case study resources are not included in the PDF of the practice exam due to copyright and other legal considerations. Many educational materials, including case studies, are often protected by copyright laws, which restrict their distribution without proper permissions. Publishers and authors maintain the rights to their original work, and including these resources in the PDF could infringe upon those rights. Therefore, to respect intellectual property laws and adhere to legal standards, these materials may be made available through alternative formats or platforms that ensure proper licensing and access control. This approach allows students to utilize the resources while remaining compliant with copyright regulations.

Regarding the other options, while length and the currency of materials could be factors in resource selection for a practice exam, they do not directly address the primary concern of copyright infringement. Additionally, the availability of case studies online might be true for some resources, but that alone does not justify their exclusion from the PDF version of the exam, which is based more on legal and copyright issues.
