What materials should not be included in the library kit for a low hostilities environment?

The correct choice is paperback books only, as these may not be suitable for a low hostilities environment due to the potential for them to be easily damaged or lost. In such environments, it is essential to prioritize materials that are durable and easily maintainable. While paperback books are valuable, they lack the robustness of other options like digital devices or educational videos, which can provide information and entertainment without the risk of physical wear and tear. Additionally, considering space and the potential for environmental damage, digital reading devices or other formats that can be easily stored and managed are often preferred.

In a low hostilities environment, materials that are resilient and have a longer lifespan tend to be favored to ensure they can withstand the conditions. Hence, including paperback books may not align with the objective of maintaining a functional and durable library kit.
