Your answers to these questions must be short (single word or expression). If the topic of your search includes an original aspect, this should be reflected in your answers.
Connect the concepts with the "AND" operator
Generally, a subject can be represented using three concepts, yet this is not always possible. These concepts must describe and cover your information need.
