python - 連続質問

Question

コード：

import json
import random

questions = json.load(open("questions.json"))

question = random.choice(questions.keys())

answers = questions[question]['answers']
correct_answer = questions[question]['correct_answer']

print question
for n, answer in enumerate(answers):
    print "%d) %s" % (n + 1, answer)

resp = raw_input('answer: ')
if resp == str(correct_answer):
    print "correct!"
else:   
    print "sorry, the correct answer was %s" % correct_answer

質問.json:

{
  "What are your plans for today?": {
    "answers": ["nothing", "something", "do not know"],
    "correct_answer": 2
  },
  "how are you?": {
    "answers": ["well", "badly", "do not know"],
    "correct_answer": 1
  }
}

このプログラムで、質問を止めずに質問を続けるように、答えが正しくても間違っていても、質問を続けられるようにするにはどうすればよいか知りたいです。
