Final answer:
The procedure for preshaping oblongs or cylinders in modeling clay or dough involves shaping the dough into the desired shapes. The process is similar to kneading bread dough, requiring the right consistency and moisture level. The shapes can vary and are made durable through firing in a kiln.
Step-by-step explanation:
The procedure for 'Preshaping Oblongs or Cylinders' in the context of modeling or working with clay or dough primarily involves shaping the dough into oblongs or cylinders. Much like the Nok culture's hand-modeled figures, the ability to shape the material into a desired form depends on achieving the right consistency. The modeling process is analogous to kneading dough for bread, where the strength of one's hands and arms plays a vital role in transforming the clay into any shape over time, and the moisture level makes the material easier to shape but also more fragile.
As for the options provided, the correct answer is that the shapes vary in shape; while they can be round like circles or elongated like cylinders, they do not always maintain a specific shape without the right handling and consistency. The right consistency ensures that the final creation maintains its form and is durable once fired in a kiln, much like the ancient figures created by the Nok civilization.
