Which pair best represents the center of the line in this drill?

• A. 1-1 and 4-4
• B. 2-2 and 3-3
• C. 1-2 and 2-3
• D. 3-1 and 4-2

Answer: (A)

In a square drill grid, the line that passes through the center is the diagonal from one corner to the opposite. This diagonal crosses the exact middle of the grid, so the endpoints that define that line show the central path most clearly. The diagonal running from 1-1 to 4-4 does just that, spanning from corner to opposite corner and passing through the grid’s center area. That’s why this pair best represents the line that goes through the center. The actual center point sits halfway along the line, between 2-2 and 3-3, but the endpoints 1-1 and 4-4 define the line that passes through that central region.
