 at 16:00. You are asked to implement a compiler for
 the WHILE language that targets the assembler language
 provided by Jasmin or Krakatau (both have a very similar
 syntax).  You can do the implementation in any programming
 language you like, but you need to submit the source code with

-\subsection*{Question 1}
+\subsection*{Task 1}
 You need to lex and parse WHILE programs, and then generate Java Byte
 Code instructions for the Jasmin assembler (or Krakatau
 assembler). For this you should use the ASTs defined in CW3 (including
 logical operators). As part of the solution you need to submit the assembler

-\subsection*{Question 2}
+\subsection*{Task 2}
 Extend the syntax of your language so that it contains also
 \texttt{for}-loops, like
 \begin{center}

+\noindent In this task you are asked to think about the following
 program:
 \begin{center}
 \begin{minipage}{12cm}
 \begin{lstlisting}[language=While, numbers=none]
 \noindent
 Note that in this program the variable \pcode{i} is used
 twice. Therefore you need to make a decision about how it should be compiled?
 What should the program print?
-\subsection*{Question 4}
+\subsection*{Task 4}
 Extend the lexer and parser to add a \textcolor{codepurple}{\pcode{break}} keyword.  Modify
 the compiler (including lexer and parser) such that when a \textcolor{codepurple}{\texttt{break}}-statement is encountered
 the code should jump out of the ``enclosing'' for/while-loop, or in case it
 is not inside such a loop to the end of the program. For example the
 should print out 0 to 10 with the first for-loop, but only 0
 to 4 in the second. Similarly it should print out \code{"Should print"},
 but not \code{"Should not print"}. For this you need to add
 a label to the end of every for- and while-loop and also to the end of the
 whole program just in case you need to jump to that label via a
-\code{break}. The file you need to be able to process for this question
+\code{break}. The file you need to be able to process for this task
 is called \texttt{break.while}.
