[18] Mid-page;
It should be noted the the One-Click Installer does not include the Tcl/Tk library (among others) and you 
will have to download them separately. Because of this, I prefer to install Ruby on Windows using

(215) Chapter 4 review question 9;
to_a was the intended answer but split(//) will work too.
Here is the difference:

irb(main):001:0> "hello there".split(//)
=> ["h", "e", "l", "l", "o", " ", "t", "h", "e", "r", "e"]

irb(main):002:0> "hello there".to_a
=> ["hello there"]
