The correct response is: Greater than, because millimeters are smaller than yards.
To clarify, when converting yards to millimeters, 1 yard is equal to 1,000 millimeters. Therefore, when you convert 2 yards to millimeters, you get:
2 yards × 1,000 mm/yard = 2,000 mm.
So, the number of millimeters (2,000 mm) is indeed greater than 2.
