This is really redundant. First you create an empty array. Then you input your 
words to a different array, then you append your word array onto the end of 
the empty array. 

And this: 
> " " + " "

just concatenates two spaces resulting in the call to 'split' being:

> words_group = gets.chomp.split("  ") # two spaces

Which won't split your input with 1 space between each word at all. The 
default argument to 'split' is a single space, so try this: 

> word_group = gets.chomp.split

which will replace your three lines above.

Use irb to explore and play with all these code snippets to get instant 
feedback on what things do!

a = ["fifth", "fourth", "third", "second", "first"]
print "Gimme wordz: "; gets.chomp.split.each { |w| puts "The #{a.pop} word is 
#{w}" }

Seriously though, try to break your problem into as little of units as 
possible, and try to solve each one by playing around in irb and using the 
online docs (links follow) if you don't have hard copies. I especially 
recommend you read about blocks, and look at the various methods in 
class "Array".
