请解答这道题---**Question Stem:** 哪边更 "重" ? (Which side is 'heavier' ?) **Chart/Diagram Description:** * Type: Schematic diagram illustrating an experiment setup on a balance scale. * Main Elements: * A balance scale with two platforms. * Left platform: Holds a beaker containing blue liquid. A white sphere labeled "乒乓球" (Ping Pong ball) is partially submerged in the liquid. The beaker has volume markings on its side. * Right platform: Holds an identical beaker containing the same amount of blue liquid. A grey sphere labeled "铁球" (Iron ball) is fully submerged in the liquid, suspended from above by a wire or string. The sphere is inside the liquid but not resting on the bottom of the beaker or supported by the beaker's weight. The beaker also has volume markings. * The balance scale beam appears level in the diagram, but accompanying text states this is a schematic and doesn't show the actual result. **Other Relevant Text:** * Label on the sphere in the left beaker: 乒乓球 (Ping Pong ball) * Label on the sphere in the right beaker: 铁球 (Iron ball) * Text below the diagram: * 文化水平过滤器 😂 (Cultural level filter 😂) * 麻烦过了九年义务教育再跟我聊天谢谢 (Please chat with me again after completing nine years of compulsory education, thank you) * 两边水一样多, 杯子一样重, 两个球体积一样大 (The amount of water on both sides is the same, the cups are the same weight, and the two balls have the same volume) * 天平只是示意图, 不表示称重结果 (The balance scale is just a schematic diagram, it does not represent the weighing result) * Watermark: Soul APP
