Query: Underlying Event Measurements at CMS   Measurements of Underlying Event activity using proton-proton collision data
collected by the CMS detector will be presented. To check the energy dependence
of the underlying event activity, results are compared with previous
measurements from different experiments at different centre-of-mass energies.
