Task: Text Categorization
Input (English): One essay claims that, like the Mona Lisa, more people consider this work "a work of art because they have found it interesting, than interesting because it is a work of art." J.M. Robertson and Minnesota professor Elmer Stoll studied it as a "stratification" with a series of authors. An essay on this literary work claims it doesn't contain any "chain[s] of events" or physical things representing "particular emotion[s]." Thomas Kyd may have written a proposed "Ur-" version of this play, which is an "artistic failure" because it lacks an "objective correlative" according to a T.S. Eliot essay on the title character "and His Problems." This plays' backstory includes poison in a king's ear. For 10 points, name this tragedy in which poisoned wine kills Queen Gertrude after a ghost talks to her princely Danish son.
Output (English): Literature
