You are given three grids, where each of them is 5 by 5 in size.
Grids have empty cells marked with "▢" and filled cells marked with "X".
Your task is to generate a referring expression that best describes the target grid while distinguishing it from the two other distractor grids.
The first grid is the target grid, and the following two grids are the distractors.

Target grid:

X X X X X
X X X X X
X X X X X

Expression: The 5 by 5 grid with four filled rows and one row of empty cells at the bottom.<|im_end|><|im_end|>

The referring expression "The 5 by 5 grid with four filled rows and one row of empty cells at the bottom" accurately describes the target grid by specifying its size, the arrangement of filled and empty cells, and the position of the empty cells relative to the filled ones. This expression distinguishes the target grid from the two distractors by highlighting the unique pattern
