[prog] I don't understand this program (-- python) how does this work??

[Guru -]

I'm really confused on how this program works
So I've pasted the entire program to the mailing list, (this may be a bad 
idea....)
Do mailing lists accept attachements?
Sorry about the length of this email
Note: not all of the indentation will be correct...
This program is taken from easytut (Non programmers tutorial for python), 
not all of the comments are mine. The program does work, I simply don't 
understand sections of it...

## This program runs a test of knowledge...(not a very good one)
#also add a menu interface, a thing to add new questions and answers,
#change questions and answers etc. etc.
#this program is quite advanced (for me)
true = 1
false = 0

#first get the test questions
def get_questions():
	#note how the data is stored as a list of lists
	return [["What colour is the sky?","blue"],\
		["What is the answer to life, the universe and everything?","42"],\
		["What is a three letter word for mouse trap?","cat"],\
		["What noise does a truly advanced machine make?","ping"]]
I understand the above section returns a list of questions and answers.

#This will test a single question
#it takes a single question in
#it returns true if the user typed the answer in the list, otherwise false
def check_question(question_and_answer):
	#extract the question and answer from the list
	#how is this going to work??
I don't understand this section at all....I don't know how it works

	question = question_and_answer[0]
	answer = question_and_answer[1]
	#give the question to the user
	given_answer = raw_input(question)
	#compare the users answer to the testers answer
	if answer == given_answer:
		print "Correct"
		return true
	else:
		print "Incorrect, correct answer was",answer
		return flase

#This will run through all the questions
def run_test(questions):
	if len(questions) == 0:
		print "No questions were given"
		#the return exits the function
		return
	index = 0
	right = 0
	while index < len(questions):
		#Check the question
		#note check_questions includes giving the question
		if check_question(questions[index]):
			right = right + 1
I don't understandthe above two lines, how does the 
check_question(questions[index): work? I know it runs check_questions(with a 
value from the list questions?)

		#go to the next question
		index = index + 1
	#notice the order of the computation first multiply then divide
	print "You got ",right*100/len(questions),"% right, out of",len(questions)
#now lets run the questions
#get_questions is the list with the questions
run_test(get_questions())

I understand parts of the program but not others. Can anyone explain how the 
sections I don't understand work?
