What would be the word on the opposite side of 'Run' if the given sheet is folded to form a cube?

The correct option is Pray.

To determine the word on the face opposite to 'Run' when the sheet is folded into a cube, we follow standard net folding rules for cubes:

1. In an open sheet (net) of a cube, faces that are in the same straight column or row with one intervening square are opposite to each other:

- 'Fly' is separated by one square ('Cry') from 'Play', so Fly is opposite to Play.

- 'Cry' is separated by one square ('Play') from 'Eat', so Cry is opposite to Eat.

2. The remaining two side-flaps must form the final pair of opposite faces:

- Therefore, Pray is opposite to Run.

Hence, the word on the opposite side of 'Run' is Pray.
