It's more clear when the query return a string (an array of char):

For example if the list 'Fruits' contains 'apple'

'Select' returns the string:

Fruits.Select(s=>s) 

[0]: "apple"

'SelectMany' flattens the string:

Fruits.SelectMany(s=>s)

[0]: 97  'a'
[1]: 112 'p'
[2]: 112 'p'
[3]: 108 'l'
[4]: 101 'e'
