      "question": "The image shows many small pieces scattered across the canvas, each clearly oriented in a specific direction, plus several larger labeled terminus markers (each marker bears a distinct letter). The piece highlighted by a green ring is the starting point. From that piece, cast an infinitely thin ray (a mathematical half-line with zero width) from its centre along the direction it points; the next step is the FIRST other marker this ray enters. A marker only counts if the ray actually crosses its boundary \u2014 grazing nearby without entering does not count. Continue until the ray enters a labeled terminus marker and report its letter. Answer with a single letter. Provide your final answer enclosed in <answer>...</answer> tags.",
