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

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

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, contrasting tabletop texture.

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 along one of its diagonals.
C. Fold it in half vertically.
D. Fold it by bringing one corner to the midpoint of the opposite side.
E. None of the above.
output: answer: B

turn: 3
modality: image
input: Based on the correct choice from the previous question, please depict the paper after performing that single valley fold and pressing it flat. The paper should remain lying flat on the table without being picked up or flipped over.
output: evaluation_points: 1. The overall shape of the paper is now an isosceles right triangle.

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

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

4. The background, table texture, and other non-paper elements are consistent with Turn 1.

turn: 4
modality: text
input: Now, starting from the folded isosceles right triangle in Turn 3, without flipping the paper over, fold it again along a line perpendicular to its 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's area, where should you make this cut?

Options:
A. Cut along the line that is the perpendicular bisector of the triangle's hypotenuse.
B. Cut along the line that is the median line parallel to the triangle's hypotenuse.
C. Cut along the line that is the altitude from the right angle to the hypotenuse.
D. Cut along the line that is the angle bisector of the right angle.
E. None of the above.
output: answer: B

turn: 5
modality: image
input: Please generate the following scenario separately: After performing the cut described in Turn 4 and removing the small square (which is 1/4 the area of the original square), completely unfold the remaining paper. Show it lying flat on the table, face-up, in its final 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. The side length of the hole is approximately half the side length of the large square.

3. The side length of the large outer square remains consistent with the original square from Turn 1.

The side length of the large outer square remains consistent with the original square from Turn 1.

The dominant visible color on the paper is light rose pink (the original front side, as specified in Turn 1).

6. The background and table texture are consistent with Turn 1.
