What will be the output of the below code segment?

class Program
{
static void Main(string[] args)
{
new List<string>() { "apple", "tomato", "grapes", "potato" }
.Intersect(new List<string>() { "apple", "mango", "grapes", "sky" })
.ToList()
.ForEach(i => Console.Write(i+" "));

Console.ReadKey(true);
}
}
