You could try like this, for single array

irb(main):019:0> a = ["item 1", "item 2", "item 3", "item 4"]
  => ["item 1", "item 2", "item 3", "item 4"]
irb(main):020:0> Hash[*a]
  => {"item 1"=>"item 2", "item 3"=>"item 4"}

for array of array

irb(main):022:0> a = [[1, 2], [3, 4]]
  => [[1, 2], [3, 4]]
irb(main):023:0> Hash[*a.flatten]
  => {1=>2, 3=>4}
