Which illustrated object makes its characteristic crack when part of its flexible tip moves faster than sound? AI reconstruction: the original asked for the earliest human-made object to break the sound barrier; this version asks about the verified physical mechanism, without asserting an exact historical first.

How many times the small sphere’s volume is the large sphere’s volume? AI reconstruction: the large sphere’s diameter is exactly twice the small sphere’s diameter; the sketch illustrates this relation but is not a measurement source.

AI reconstruction: The written question was missing. The upper pair shows a transformation. Apply the same changes to the lower-left picture. Which option belongs in the lower-right box? Compare the shapes, positions, shading and directions.

AI reconstruction. Compare the two pictures in each column. The spoon keeps the same orientation, while the fork turns 180° about the shared meeting point. Which picture belongs in the empty upper cell? The spoon is the orange-handled utensil; the fork has the green handle.

Bark is to tree as scales are to which choice?

AI reconstruction: Language: uppercase English A–Z, digits 0–9; punctuation hash (#), equals (=), slash (/), dollar sign and cent sign (¢). Rules: (1) end with /; (2) start with the next English letter after the preceding printed series; (3) the second of two adjacent uppercase letters may be replaced by a digit; (4) 5 may not be adjacent to another 5; (5) every other digit may occur at most once. Model: A1AA#2/. Enter C if correct or I if incorrect. The preceding printed series starts with C. Check the series shown below. Added condition: Treat these as the complete checks: digits may occupy the displayed positions; rule 3 permits replacement but does not impose an additional fixed-position template. Punctuation may repeat, with no length limit stated.

AI reconstruction: Choose the missing colored grid. Added rule: Within each matrix row, repeat the same cyclic vertical shift shown between its first two grids. Move whole horizontal pairs together, wrapping pairs that leave one end to the other end. The shift direction may differ between matrix rows.

AI reconstruction (instruction): Complete the matrix so that each row and column contains each color once and each wrapping style once: a solid rounded box with a bow, a divided square box with a bow, or a divided square box without a bow.

AI reconstruction (instruction): Choose the missing fish. Added rule: every row and column contains each marking color (red, blue, green) once and each size (small, medium, large) once. Compare relative sizes within the illustration.

AI reconstruction: Added condition. Split the list into consecutive groups of three. In each group, the third number is twice the absolute difference between the first two: subtract the smaller of the first two numbers from the larger, then double the result. Choose the missing number.

Which option can be added to the remaining blocks to make an exact copy of the target solid? You may rotate the added piece.

Target solid:


Remaining blocks:

AI reconstruction: Choose the missing picture. Added condition: Across all nine small grids, each of the nine cell positions must be coloured blue exactly once.

AI reconstruction: The written instruction was missing. Each lower solid is a rigid rotation of the solid directly above it. Which option can replace the question mark? Keep every unit cube; do not add cubes or leave concealed cavities in otherwise solid portions.

AI reconstruction. Continue the three-position ring pattern. At every step, move the outer-ring colours one position left cyclically, and the inner-ring colours one position right cyclically. Keep the three centres fixed. Which picture comes next?

AI reconstruction. Added condition: in each row, the left design is made by laying the middle and right designs over one another, with their centres aligned and without rotation. Shared lines remain visible once. Which right-hand design completes the bottom row?

AI reconstruction (instruction): Complete the matrix so that each row and column contains one circle, one square and one heart, and exactly one horizontal rod. For the LAST ROW ONLY, additionally require one, two and three short end bars once each. This last-row bar condition is an added assumption: the middle row visibly has 1, 3, 3 bars and does not follow a global one-of-each bar-count rule.

Which option shows the figure in the grey box folded along the dotted line? Compare the reflected flap with the part that stays still.

Which set of blocks can be put together to make the solid on the left? Keep each solid piece intact, including its colour and the block boundaries.

cranium, scapula, sternum, humerus, femur, ?
Choose the one answer meeting the stated criterion.
AI reconstruction — added criterion or response task: Continue the list with a bone of the lower leg; compare anatomical categories, not a claimed exact spatial ordering of every earlier term.

The first picture is the target. Which option can be added to the piece in the grey box to make exactly that target, without rotating either piece? Slide the chosen piece into place without overlap.
