Answer:
false.
Step-by-step explanation:
Novellas have come to represent a whole literary genre all on their own. They are usually identified by their length and, often, by the way the plot is set. A novella is longer than a short story, but not much, and it tends to be, for that reason, still shorter than a novel. A novella tends to develop a problem which is based on this premise: what has happened? A short story, on the other hand, often develops the contrary: what will happen?
