Target concept: Parliamentary Public Administration Structure: The Prime Minister occupies the core of the organizational structure, with a reporting system that operates parallel to the parliament.

Video generation prompt: Display the Prime Minister and the parliament on the canvas. Add the departments one by one to illustrate a simplified organizational chart of the parliamentary public administration structure. Use clear lines to show the relationships between the parliament, the Prime Minister, and the departments.

Evaluation guide:
(i) Target concept: Parliamentary public administration structure with Prime Minister as central executive authority accountable to parliament via parallel reporting, not hierarchical subordination.
Minimum mechanism: Visual encoding must support two non-nested, co-visible institutional nodes (parliament, PM) with explicit bidirectional or parallel accountability (line), and all departments must be unambiguously downstream of PM only.
(ii)Storyline: Frame 1–2: Parliament and Prime Minister appear simultaneously, fixed in place, side-by-side. Frame 3: Line appears between them, fully drawn. Frame 4–6: First department appears, then line from PM to it draws fully. Frame 7–9: Second department appears, then its line draws fully. Frame 10: Third department appears, then its line draws fully. Throughout: No entity moves, resizes, or disappears; no new lines appear except those specified; viewpoint remains static and front-facing; all labels remain fully visible and unoccluded.

Experimental Procedure
1. Display parliament and Prime Minister side-by-side on canvas.
2. Draw a clear line connecting parliament to Prime Minister.
3. Add one department at a time; after each addition, draw a line from Prime Minister to that department.
Observation of Experimental Phenomena
- Parliament and Prime Minister appear simultaneously and remain fixed.
- Departments appear sequentially (not all at once), each only after the previous is fully displayed and connected.
- Every department is connected exclusively to Prime Minister — never to parliament or to another department.
- All connecting lines are continuous, unbroken, and persist throughout.
Summary of Experimental Principles
The parliamentary public administration structure centers the Prime Minister, who reports to parliament through a parallel accountability system — not subordination. Departments report solely to the Prime Minister, forming a simplified hierarchical chart where parliament and PM are distinct, co-constitutive nodes.

Prompt Grounding rubric:
level_1: No parliament node, Prime Minister node, or department node appears anywhere on the canvas; the canvas shows unrelated shapes, text, or is empty; no line of any kind is drawn.
level_2: At least one of the parliament node, the Prime Minister node, or a department box appears, but its label is missing or illegible, its position keeps changing, and no line of any kind connects it to anything else; if departments appear, more than one appears at the same time rather than one at a time.
level_3: Parliament and Prime Minister both appear as two separate, legibly labeled nodes; at least one department box also appears; at least one line connects two of these nodes; departments do not yet appear strictly one at a time (e.g., two appear together, or a department appears before both parliament and Prime Minister are shown).
level_4: Parliament and Prime Minister both appear as separate labeled nodes before any department appears; departments then appear one at a time, never two in the same moment; each department, as soon as it appears, is joined by a line to another node already on canvas; a line also joins parliament and Prime Minister; every label stays legible and every node stays in the same spot for the rest of the clip.
level_5: Parliament and Prime Minister appear together first, each keeping a fixed position and a legible label for the whole clip, joined by a single line that is never redrawn; departments then appear strictly one at a time, with no two department boxes shown for the first time in the same moment; each new department is joined by a line to another node already present within moments of appearing; no extra boxes, lines, or labels appear beyond what the prompt describes.

Scientific and Causal Correctness rubric:
level_1: No line at all joins parliament and the Prime Minister, or every department in the scene is wired to parliament instead of to the Prime Minister, implying departments report directly to parliament rather than through a parallel Prime-Minister-centered structure.
level_2: Parliament and the Prime Minister are drawn with an inverted relationship: for example the Prime Minister node sits beneath or visually subordinate to parliament, or a line/arrow points from the Prime Minister up into parliament as if reporting to a superior; or at least one department is wired to parliament instead of to the Prime Minister; or a second department is wired in before the Prime Minister node has even appeared.
level_3: Parliament and the Prime Minister appear as two distinct, non-nested nodes with no subordination implied by their layout; at least one department is correctly wired to the Prime Minister; but at least one other department is instead wired to parliament, or the parliament–Prime-Minister line is missing or its direction is ambiguous.
level_4: Every department shown in the scene is wired only to the Prime Minister node, never to parliament and never to another department; the parliament–Prime-Minister line is present and stays unbroken; no department appears before the Prime Minister node exists; parliament and the Prime Minister remain two separate, side-by-side nodes rather than one nested inside the other, consistent with a parallel-reporting relationship rather than a chain of command.
level_5: All conditions of score 4 hold, and in addition every department without exception connects only to the Prime Minister; the parliament–Prime-Minister connection never uses an arrowhead or line style suggesting parliament commands the Prime Minister; every line in the scene shares the same style and thickness, so a viewer reads all department links as reporting to the Prime Minister and the single parliament link as a distinct, parallel accountability relationship rather than a hierarchy.

Spatiotemporal Consistency rubric:
level_1: The parliament node, the Prime Minister node, or a department box vanishes and then reappears later in the clip; any node jumps instantly from one spot to another; a department box appears already sitting in the middle of the canvas with no box being drawn or fading in; the whole chart's lighting flips abruptly, such as the background suddenly darkening then brightening partway through.
level_2: A node (parliament, Prime Minister, or a department) blinks off and back on at least once; a department box appears from outside the visible canvas with no visible slide-in or draw-in motion; a connecting line appears already half-drawn instead of being drawn continuously from one end to the other; the camera view pans, tilts, or zooms at any point instead of holding still.
level_3: Once shown, parliament, the Prime Minister, and every department box stay visible for the remainder of the clip with no blinking or disappearing; every connecting line is drawn continuously from one endpoint to the other rather than snapping into place in pieces; small imperfections remain, though: for example a department box briefly overlaps and covers part of the Prime Minister's label, or a line's thickness visibly changes partway through being drawn.
level_4: Every node keeps the exact canvas position where it first appeared, with no drifting or resizing; no department box ever overlaps or covers another node's label; every line is drawn smoothly from start to end in one continuous motion, with no gaps, restarts, or sudden changes in thickness; the camera framing and the scene's lighting stay the same for the entire clip.
level_5: Every node (parliament, the Prime Minister, and each department) appears once, settles into a fixed, non-overlapping position, and is never redrawn or repositioned; every connecting line is drawn in one smooth, continuous stroke of constant thickness from its starting node to its ending node; the background lighting and camera framing are identical from the first frame to the last, with no flicker, warp, or shape distortion at any point.
