The problem presents a list of terms related to art and sculpture methods, and it seems to be asking which method involves the movement of large amounts of soil. Let's analyze the options: 1. **Casting**: This method involves pouring liquid material (like metal or plaster) into a mold to create a sculpture. It does not typically involve moving soil. 2. **Readymades**: This term refers to ordinary manufactured objects that are designated as art. It does not involve soil movement. 3. **Earthworks**: This method specifically involves the manipulation of the earth and soil to create large-scale sculptures or installations. It often requires moving large amounts of soil from one location to another. 4. **Constructing**: This is a general term that could refer to building or assembling various materials, but it does not specifically imply soil movement. Based on this analysis, the correct answer is **earthworks**, as it is the method that involves the movement of large amounts of soil.
