The correct answer to this open question is the following.
Sculpture 1 is made of sand. It could be located on a beach or in the desert. Its forms were made by sand in combination with water to make it more resistant and for the creation of forms. The second one is a sculpture made of rock. It is a human figure that reflects stability, reflexion or peace. It is located in a complex that could be part of a garden area. The important thing is the way each sculpture relates to the environmet as we have mentioned above. The environment is what gives a great deal of meaning to the sculptures because both are associated: the sculpture and the kind of environment. A sand sculpture in the main square of a downtown area in Chicago probably is not the best place for it. Or a peaceful human sculpture in the aisles of a manufacturing plant in Detroit is not the best place for it. The environment has a lot to do with the significance of the sculpture.
