Answer:
False
Step-by-step explanation:
Scenery include all the above.
Scenery is that which is deployed as a setting for a theatrical production.
As said earlier, it can be anything (the size doesn't matter, whether big or small) and there's no end to the list. It may be a table, curtain, some art work like painting, a ball, a road or even the whole street.
It doesn't matter if it is genuine or custom created, as long as it is usable for theatrical purpose, then it is appropriate to be refer to as scenery.
