What conclusion can be drawn from the fact that many cave paintings are located in difficult-to-reach areas?

It could be inferred that the images in the paintings were important to the painter

Explanation: The making of a cave painting involved a lot of effort by the individual in terms of the amount of time and energy needed in order to gather the necessary items. Pigments were prepared from plant extracts; after identifying suitable plants, comes extraction and preparation of different colours.

Also, the paintings made in difficult to reach areas of the cave involved risks of negotiating dangerous areas of the caves. Taking all these into account would seem to indicate that the motivation to produce the paintings was strong and that the objects or subjects of such artistic labour were important to the cave painters.
