irb(main):001:0> a1 = ["joe blogs", "peter smith"]
=> ["joe blogs", "peter smith"]
irb(main):002:0> a2 = ["carpenter", "policeman"]
=> ["carpenter", "policeman"]
irb(main):003:0> a1.zip(a2).each {|name, occupation| puts "#{name} is
a #{occupation}"}
joe blogs is a carpenter
peter smith is a policeman

Another way that avoids creating the intermediate array would be to
iterate using the index:

irb(main):004:0> a1.each_with_index {|name, i| puts "#{name} is a #{a2[i]}"}
joe blogs is a carpenter
peter smith is a policeman
=> ["joe blogs", "peter smith"]

Jesus.
