1. **Is the object a long rectangular prism?**
   - **Answer:** Yes
   - **Reasoning:** The images show an object with a rectangular shape in three dimensions, consistent with the characteristics of a rectangular prism. The length of the object is greater than its width and height, which supports the description of it being a "long" rectangular prism.

2. **Is there a semi-circle cut out from the length of the rectangular prism?**
   - **Answer:** Yes
   - **Reasoning:** In all three images, there is a visible semi-circular cutout along one of the longer sides of the rectangular prism. This cutout is consistent across the different angles shown in the images.

3. **Is the semi-circle cut out along the entire length of the prism?**
   - **Answer:** No
   - **Reasoning:** The images show that the semi-circle cutout does not extend along the entire length of the prism. The cutout is visible as a distinct, localized feature on the side of the prism, not spanning its full length.
