1. **Is the 3D object rectangular in shape?**
   - **Answer:** Yes
   - **Reasoning:** The object has a base shape that is rectangular, with four sides where opposite sides are parallel and equal in length. The images show that the main body of the object maintains these characteristics.

2. **Does the object have a semi-circular cutout?**
   - **Answer:** No
   - **Reasoning:** The images show that the object has a cutout, but the shape of the cutout is not semi-circular. It appears to be more of a triangular or trapezoidal cutout rather than a semi-circle.

3. **Is the flat edge of the semi-circle on the longer side of the rectangle?**
   - **Answer:** Unclear
   - **Reasoning:** Since the object does not have a semi-circular cutout as determined from the previous question, it is unclear how to answer this question about the orientation of a semi-circular cutout's flat edge.

4. **Is the semi-circle negatively extruded to create a cutout in the original rectangular object?**
   - **Answer:** Unclear
   - **Reasoning:** As established, the object does not have a semi-circular cutout. Therefore, it is unclear whether there is any negative extrusion of a semi-circle to create a cutout, since the cutout present does not match the description of being semi-circular.
