Hint 3 of 3
Cross out any picture where two parts have swapped places.
Show solution
Approach: keep the parts in the same order when curled
- Curling up never lets a part jump over its neighbour, so the order from head to tail must stay the same.
- Read the straight caterpillar's parts in order, then follow that same order around each curled picture.
- Only one curled picture keeps every part in its correct spot: A.
