turn: 1
modality: image
input: Generate a square piece of origami paper lying flat on a table, face-up, with all four sides aligned horizontally or vertically. The visible side of the paper is light green, and the hidden side is dark purple.
output: evaluation_points: 1. A standard square sheet of paper is centered in the image.

2. The visible side of the paper is a solid light green color.

3. The paper is perfectly flat with no visible creases.

4. All four edges of the square are aligned horizontally or vertically, not tilted.

5. The background is a simple tabletop texture that contrasts with the paper color.

turn: 2
modality: text
input: To transform this square paper into an 'isosceles right triangle' with just a single fold, which folding method should be used?
Options:
A. Fold the paper in half horizontally.
B. Fold the paper in half vertically.
C. Fold the paper along one of its diagonals.
D. Fold the paper by bringing one corner to the midpoint of the opposite side.
E. None of the above.
output: answer: C

turn: 3
modality: image
input: Based on the previous selection, perform that single valley fold (without lifting or flipping the paper entirely) and press it flat. The paper should remain lying on the table.
output: evaluation_points: 1. The overall shape is now an isosceles right triangle.

The length of the triangle's legs is equal or very close to the side length of the original square from Turn 1.

3. The dominant visible color is dark purple (the back side of the paper).

The background, table texture, and other non-essential elements are identical to Turn 1.

turn: 4
modality: text
input: Now, starting from the folded isosceles right triangle in Turn 3 (do not flip the paper), fold it again along the 'perpendicular to the hypotenuse' and press it flat. Then, make a single straight cut. To obtain a small square with an area equal to 1/4 of the original square after cutting, where should the cut be made?
Options:
A. Cut along the line parallel to the triangle's hypotenuse, positioned at its midpoint (the triangle's midsegment parallel to the hypotenuse).
B. Cut along the line from the right angle vertex to the midpoint of the hypotenuse.
C. Cut along the line parallel to one of the triangle's legs, positioned halfway from the leg to the hypotenuse.
D. Cut along the line that is the perpendicular bisector of the triangle's hypotenuse.
E. None of the above.
output: answer: A

turn: 5
modality: image
input: Generate the following separately: After performing the cut described in Turn 4 and removing the small square (area = 1/4 of the original), completely unfold the remaining paper. It should be laid flat, face-up, in its square form.
output: evaluation_points: 1. The unfolded shape is a square frame: a large square with a smaller square hole at its exact center.

2. The edges of the central square hole are parallel to the edges of the large outer square. The side length of the hole is approximately half the side length of the large square.

The overall side length of the large square remains essentially the same as in Turn 1.

4. The dominant visible color on the paper is light green (the original front side).

Two clear, perpendicular creases (forming a cross) are visible on the paper, each connecting opposite corners of the large square.

The background and table texture are identical to Turn 1.
