Hi Alan,
Thanks for the suggestion, but I am not sure it is what I am after. From 
your dictionary, for example, I wanted to have a list as:

"what is your name?"
"where do you live?"

then the next time I run the program I will get:

"who are you?
"what is your address?


rather then, what I have now is:

"what is your name?"
"who are you?"

I have updated the code as you suggested to:

import random
n_questions = 5
q = {'1': ['1a', '1b', '1c'],
      '2': ['2a', '2b', '2c'],
      '3': ['3a', '3b', '3c'],
      '4': ['4a', '4b', '4c'],
      '5': ['5a', '5b', '5c'],
      '6': ['6a', '6b', '6c'],
      '7': ['7a', '7b', '7c'],
      '8': ['8a', '8b', '8c']

if len(q) > n_questions:
     q_keys = random.sample(q.keys(), n_questions)
     q_keys = q.keys()
a = [q[x] for x in q_keys]
print a

which returns:

[['2a', '2b', '2c'], ['4a', '4b', '4c'], ['5a', '5b', '5c'], ['7a', 
'7b', '7c'], ['8a', '8b', '8c']]


So from this how do I choose a random element and produce a new 
dictionary like for example:

[2a, 4b, 5c,  7b, 8c]
