The term 'not occurring naturally' can be summarized by two crossword solutions: 'STAGED' and 'made'. STAGED means to plan or arrange something in advance, usually for a specific purpose. It is often used in the context of theatrical performances, where the actors and actresses are directed to act out a scene in a certain way. Made, on the other hand, means to create or construct something. It is often used when referring to the creation of physical objects, such as furniture or clothing. Both terms imply that the object or event was not created or arranged naturally, but rather through human intervention.
