Quiz: Boolean operations with non-Boolean data

What is the result of each line of code in the below examples?

1

True	`True && True` is (: True, False :)
string 'True'	`'True' && 'True'` is a (: Boolean True, Boolean False, string 'True', string 'False' :)	These are strings, which in Boolean context are `True` values.
string 'Beta'	`'Alpha' && 'Beta'` is a (: Boolean True, Boolean False, string 'Alpha', string 'Beta' :)	The result is the second string.

2

True	`True		True` is (: True, False :)
string 'True'	`'True'		'True'` is a (: Boolean True, Boolean False, string 'True', string 'False' :)
string 'Alpha'	`'Alpha'		'Beta'` is a (: Boolean True, Boolean False, string 'Alpha', string 'Beta' :)	The result is the first string.

3

200	`100 && 200` is (: 100, 200, True, False, Nil :)
100	`100		200` is (: 100, 200, True, False, Nil :)
Nil	`100 ^^ 200` is (: 100, 200, True, False, Nil :)	`Nil` is the value to represent the absence of a value.
