* @name Conditionals 2
* @arialabel The top half of the window has spaced out vertical lines. The bottom half of the window has more condensed vertical lines
* @description We extend the language of conditionals from the previous
* example by adding the keyword "else". This allows conditionals
* to ask two or more sequential questions, each with a different
* action.
