Datasets:
| The input contains 4 blocks in 2 stacks. From left to right: | |
| - Stack 1 has 1 level. Level 1 has a orange block. | |
| - Stack 2 has 3 level. From bottom to top: level 1 has an purple block, level 2 has an red block, level 3 has an yellow block, | |
| As such, for the question "What is the spatial relation betweeen the blue block and the purple block?",since the blue block does not exist in the demonstrated configurations, the correct answer is "<Output> D". | |
| <Output> D |
