turn: 1
modality: image
input: Generate a square sheet of origami paper lying flat on a table, face-up, with all four sides aligned horizontally or vertically. The front side of the paper is light lavender gray, and the back side is deep red.
output: evaluation_points: 1. The image should show a standard square sheet of paper at its center.

2. The visible side of the paper should be a solid color matching 'light lavender gray'.

3. The paper should be completely flat with no visible creases or folds.

4. All four edges of the square must be perfectly horizontal or vertical, not tilted.

5. The background should be a simple tabletop texture, providing clear contrast with the paper's 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 be used?
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 midpoint of the opposite side.
E. None of the above.
output: answer: C

turn: 3
modality: image
input: Based on the previous selection, please depict the paper after performing that single valley fold and pressing it flat. The paper should remain lying on the table without being fully lifted or flipped over.
output: evaluation_points: 1. The overall outline of the paper should now be an isosceles right triangle.

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

3. The dominant visible color should be the back side color: deep red.

The background, tabletop texture, and any other non-essential elements must remain completely consistent with the `Turn 1 output image`.

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 the 'perpendicular to the hypotenuse' and press it flat. Then, perform a single straight-line 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 the midpoint of the altitude from the right angle to the hypotenuse (i.e., the triangle's midsegment parallel to the hypotenuse).
B. Cut along the altitude from the right angle to the hypotenuse.
C. Cut along the line connecting the midpoints of the two legs of the triangle.
D. Cut along the line that is the angle bisector of the right angle.
E. None of the above.
output: answer: A

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), completely unfold the remaining paper. It should be returned to a flat, face-up, square state.
output: evaluation_points: 1. The fully unfolded shape should be a square frame: a large square with a smaller square hole missing from its exact center.

2. The edges of the central square hole must be parallel to the edges of the large outer square. The side length of the hole should be approximately half the side length of the large square.

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

4. The dominant visible color on the paper's face should be light lavender gray.

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

The background and tabletop texture must be completely consistent with the `Turn 1 output image`.
