The pieces are colored: a large red triangle, a large yellow triangle, a medium purple triangle, a small orange triangle, a small blue triangle, a green square, and a dark blue parallelogram. * **Outline Shape:** An outline resembling the trunk and lower branches of a tree, or the letter 'Y'. The upper left part of the shape is filled with a light blue color, representing water. Two small yellow dots are visible near the blue area. * **Other Graphics:** Two small pink flowers, one small yellow flower, and a cartoon rabbit wearing a red bow and green clothes are present as decorative elements. * **Relative Position:** The outline shape is on the left side of the image, and the tangram square is on the right side. The speech bubble is at the top. The decorative graphics are scattered around the outline shape. **Interpretation/Context (Based on the text and visuals):** The image presents a problem related to tangrams. The text says it's a "Tangram Experiment Question 3-5". It mentions that tangrams can be used to form a big tree and asks the user to assemble it. The outline shape on the left is likely the target shape (a tree) that needs to be formed using the tangram pieces shown on the right. The blue area might indicate a starting piece or a water level.
