turn: 1
modality: image
input: Generate a square piece of origami paper lying flat on a table, face-up, with all four sides perfectly horizontal or vertical. The front side of the paper is light pink, and the back side is dark green.
output: evaluation_points: 1. The image shows a standard square piece of paper at the center.

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

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

4. All four edges of the square are aligned horizontally or vertically, not at an angle.

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

turn: 2
modality: text
input: To transform this square sheet into an 'isosceles right triangle' using only a single fold, which folding method should you use?
Options:
A. Fold it in half horizontally.
B. Fold it in half vertically.
C. Fold it along one of its diagonals.
D. Fold it by bringing one corner to the opposite side's midpoint.
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 flatten it. The paper should remain lying flat on the table.
output: evaluation_points: 1. The overall shape of the paper is now an isosceles right triangle.

2. 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 green (the back side).

The background and table texture are identical to the Turn 1 input image.

turn: 4
modality: text
input: Now, starting from the folded isosceles right triangle in Turn 3 (without flipping the paper), fold it again along a line perpendicular to the triangle's hypotenuse and flatten it. 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 you make the cut?
Options:
A. Cut along the triangle's altitude from the right angle to the hypotenuse.
B. Cut along the triangle's median line parallel to its hypotenuse.
C. Cut along the triangle's leg.
D. Cut along a line from the midpoint of one leg to the midpoint of the hypotenuse.
E. None of the above.
output: answer: B

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 piece. It should be restored to a flat, face-up, square state.
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, and the hole's side length is approximately half the side length of the large square.

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

The dominant visible color on the paper's face is light pink, as specified for the front side in Turn 1.

5. Two clear, perpendicular creases (forming a cross) are visible on the paper, each running from one corner of the large square to the opposite corner.

6. The background and table texture are identical to Turn 1.
