Subject: Trouble with local variables

Hello everyone!
I've been coding with Ruby for about three days, and I just ran into my
first big snag. I've been working on a quiz, and the first one had
questions like this:

puts 'How many classes have a taunt kill?'
puts 'A - Three'
puts 'B - Four'
puts 'C - Five'
puts 'D - Six'
answer = gets.chomp.downcase
if (answer == 'd')
  score = score + 1
else
end

But it's messy, since I have to repeat the code for every question. (I
know, I know, DRY). With this in mind, I began construction on quiz2,
and used this as my prototype:

def check
answer = gets.chomp.downcase
if (answer == c_answer)
  score = score + 1
else
  puts 'The correct answer was ' + c_answer + '.'
end
end
puts 'Which is the slowest class?'
puts 'A - Pyro'
puts 'B - Demoman'
puts 'C - Heavy'
puts 'D - Soldier'
c_answer = 'c'
check

I understand the problem (mostly), but I'm looking for a workaround.
Most of my 'fixes' don't work because of the 'A, B, C, D' system; should
that system be changed?

Sorry for such a long post, I've just really gotten into this.
