A long exposition differs from a typical stage direction because a stage direction is usually brief. An exposition, however, goes into more detail. A stage direction also just usually tells the setting or where or what the character is doing, or how the stage looks. An exposition shows history and goes full out on the setting.
The answer would be true. Hope this helps.
