Multiple Where clauses in Lambda expressions

Question

I have a simple lambda expression that goes something like this:

x=> x.Lists.Include(l => l.Title).Where(l=>l.Title != String.Empty)

Answer 1

x=> x.Lists.Include(l => l.Title).Where(l=>l.Title != String.Empty).Where(l => l.Internal NAme != String.Empty)

or

x=> x.Lists.Include(l => l.Title).Where(l=>l.Title != String.Empty && l.Internal NAme != String.Empty)
