In the puzzle’s simplified setup, Glass A, containing the paperclip, holds the most water. The explanation is displacement: an object’s submerged portion occupies space that water would otherwise fill. With identical glasses and matching surface levels, the smallest submerged volume leaves the greatest volume for water. The paperclip is assumed to occupy the least space, while the baseball occupies the most. The eraser and wristwatch fall between them under the illustration’s stated assumptions.
Imagine carefully removing each object without spilling any water. The remaining water would make the difference easier to see: matching starting levels did not mean matching amounts. However, this is a visual reasoning puzzle, not a reliable personality test. Picking another glass cannot establish that someone is selfish, generous, or uncaring. The worthwhile takeaway is gentler: first impressions sometimes overlook important details, and reconsidering an answer is an opportunity to understand—not a reason to judge yourself.
