If you are really just working with two arrays that map one-to-one and
onto each other, why not use one array? An array of hashes perhaps.
Like:

q_and_as = [ {:question => 'Is it blue?', :answer => 'Yes'},
{:question => 'Is it round?', :answer => 'No'} ]

Then use Array's each method:

q_and_as.each do |query|
  puts "<td>#{query[:question]}</td>"
  puts "<td>#{query[:answer]}</td>"
end

HTH,
