Multiple WebPresences per Market - root URL resolution

Markets
1

I have 2 related and similar questions in regards to newmarkets.

  1. With newmarkets coming in, 1 region can now be in multiple markets. In the following markets setup, which URL will a customer browsing from the US see, and how is that determined?

  2. With newmarkets coming in, 1 market can now have multiple web presences. So how is the correct root URL decided for a customer who matches a specific market which has more than one web presence?

Thank you.
