This scarcity necessitates prioritization and trade-offs, as societies must decide how to allocate resources effectively to satisfy various demands.

eliminating choices
The paired statements in a dichotomous key must be opposite in order to present two mutually exclusive choices that lead to the correct identification of an organism. This system helps users narrow down the possibilities at each step until reaching the correct classification.

The first is being able to identify your audience. The second key to effective writing is establishing a purpose. The third key is formulating your message. The final key to effective writing is selecting your style and tone.
