Answer 2

Pushing the Torricelli tube further into the cup will decrease the air volume above the liquid, causing an increase in atmospheric pressure. This, in turn, will force the liquid to rise higher in the tube due to the pressure difference between the decreased air pressure in the closed space and the atmospheric pressure outside.
