The scene shows an analogy A→B→C :: D→?→? with two rows of shapes. Top row: color_155 circle at medium becomes color_246 circle at medium, then color_246 circle at small. This shows two rules: first change color from color_155 to color_246, then change size from medium to small. Bottom row: oval starts with color_155 and medium. Apply the same transformation: first change color to color_246, then change size to small. Only modify what the task requires; keep the background and any other element unchanged. Output 1 image showing the completed analogy.
