The rigid mural roll is 2.4 metres across at its narrowest cross-section, while the rectangular storage hatch is 1.6 metres high and 1.2 metres wide. Without unrolling or deforming it, the mural ___ through the hatch.

توضیح

Using could not states the impossibility established by a rigid roll whose narrowest cross-section exceeds both hatch dimensions. Might not fit would leave room for uncertainty, but no rotation can make the stated roll pass through that opening intact.
