Novelists cannot become great as long as they remain in academia. Powers of observation and analysis, which schools successfully hone, are useful to the novelist, but an intuitive grasp of the emotions of everyday life can be obtained only by the kind of immersion in everyday life that is precluded by being an academic. Which one of the following is an assumption on which the argument depends? ['Participation in life, interspersed with impartial observation of life, makes novelists great.', 'Novelists require some impartiality to get an intuitive grasp of the emotions of everyday life.', 'Novelists cannot be great without an intuitive grasp of the emotions of everyday life.', 'No great novelist lacks powers of observation and analysis.']
