Which is more expendable in a jungle a book or a repellent?

In a jungle, a repellent is generally more essential than a book. Repellent helps protect against insect bites and diseases, which can be crucial for survival and health in such an environment. While a book can provide valuable information or entertainment, it is less critical in terms of immediate safety and well-being. Therefore, in terms of expendability, a book is more expendable than a repellent.
