Evian

Here's an interesting ads of Evian Water I found in Google:



This ads stated that:
Get skin so goodYou want to show it off
74% of people drinking an extra liter of Evian pure natural mineral water per
day notice their skin looking smoother, more hydrated, and as a result visibly
younger

The objective of this ads actually is to convince people to purchase the Evian Mineral Water advertised, so the unstated conclusion of this ad that we should buy and drink Evian brand mineral water...

The premise is, if you drink Evian Mineral water, your skin will look better, assuming that eveyone likes better-looking skin. However, what we realy see in the conclusion that our skin will look better only if we drink evian.

Probably, we could get our skin smoother and more hydronated by drinking any brand of mineral water, not only Evian! Or, probably again, non mineral water like old tap water, will also can make the same effect. Even fluids will likely works, such as fruit juices and milk. In other words, drink an extra liter of water or just extra fluids and you will get better looking skin, more hydrated, and visibly younger!

In contrast, suppose that drinking were a necessary condition for smoother skin, then we would just have to go out and buy Evian. Fortunately, the ad doesn't give us a good reason to buy an expensive mineral water, rather than just drinking more of the drink we want!
