A proposition is said to be tautological if its constituent terms repeat themselves or if they can be reduced to terms that do, so that the proposition is of the form "a = a" ("a is identical to a").
I would assume it is in two parts so that the "Smores" tests can be run to see if the Nestle's chocolate is the "very best chocolate".....you have to be semi "old" to understand that lil jingle reference me thinks..... The $39 Billion offered for 77% of Alcon is staggering for it's content and return capabilities for the acquirer imho. $39 Billion creates one "sweet" war chest to go on an acquisition binge in the food industry if that is Nestle's plan down the road.....either way, it is a sugary deal for the Nestle's crew.....
