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 ▢ ▢

Distractor grid 1:

▢ ▢ X ▢ ▢
▢ ▢ X ▢ ▢
X X X X X
▢ ▢ X ▢ ▢
▢ ▢ X ▢ ▢

Distractor grid 2:

▢ ▢ X ▢ ▢
▢ X X X ▢
X X X X X
▢ ▢ X ▢ ▢
▢ ▢ X ▢ ▢

Instruction: Describe the target grid.
Generate the referring expression starting with the tag "Expression: " for the given target grid. Omit any other text.
Expression: The grid with the horizontal line of five X's in the middle row, and two X's in the second and fourth rows that are directly above and below the middle X in the first column.||

Expression: The target grid has more empty cells than either of the distractor grids, particularly in the upper-left and lower-right corners. It also contains fewer X's overall, with only one instance in the center compared to three for each distractor grid. Additionally, there are no adjacent X's in the target grid, while both distractor grids have at least one pair of adjacent X's. Overall, the target grid is characterized by its greater number of
