Here are some ideas :

1) you should add a specific character before every lines that start by a number.
this way, you can use this character as a record separator and retrieve questions by there records number (easy using awk)

2) you should store the total number of record/questions into a variable, because you may need it :
- if you are at the last questions and press N "Next" into the menu, you could therefore go to question 1
- if you are in question 1 and press P "Previous" then you could easily go to the last equestions.

3) Since you are going to do repeted task (display question and ask choice) you should consider building that call into a function that would take (for example) the questions number as arguments

QUIZ(6) 							 BSD Games Manual							   QUIZ(6)

NAME

     quiz -- random knowledge tests

SYNOPSIS

     quiz [-t] [-i file] [question answer]

DESCRIPTION

     The quiz utility tests your knowledge of random facts.  It has a database of subjects from which you can choose.  With no arguments, quiz
     displays the list of available subjects.

     The options are as follows:

     -t      Use tutorial mode, in which questions are repeated later if you didn't get them right the first time, and new questions are presented
	     less frequently to help you learn the older ones.

     -i      Specify an alternative index file.

     Subjects are divided into categories.  You can pick any two categories from the same subject.  quiz will ask questions from the first cate-
     gory and it expects answers from the second category.  For example, the command ``quiz victim killer'' asks questions which are the names of
     victims, and expects you to answer with the cause of their untimely demise, whereas the command ``quiz killer victim'' works the other way
     around.

     If you get the answer wrong, quiz lets you try again.  To see the right answer, enter a blank line.

   Index and Data File Syntax
     The index and data files have a similar syntax.  Lines in them consist of several categories separated by colons.	The categories are regular
     expressions formed using the following meta-characters:

	   pat|pat  alternative patterns
	   {pat}    optional pattern
	   [pat]    delimiters, as in pat[pat|pat]pat

     In an index file, each line represents a subject.	The first category in each subject is the pathname of the data file for the subject.  The
     remaining categories are regular expressions for the titles of each category in the subject.

     In data files, each line represents a question/answer set.  Each category is the information for the question/answer for that category.

     The backslash character (``'') is used to quote syntactically significant characters, or at the end of a line to signify that a continuation
     line follows.

     If either a question or its answer is empty, quiz will refrain from asking it.

FILES

     /usr/share/games/quiz.db  The default index and data files.

BUGS

     quiz is pretty cynical about certain subjects.
