[Tex/LaTex] Hanging line indentation with enumerate

#enumerateindentationlists

I'm writing a multiple choice text in latex, and I've been having some problems with the identation. I successfully indented all my text using

\begin{enumerate}
{\setlength\itemindent{15pt}\item[1)] Select one of the following:}
\vspace{0.2cm}
{\setlength\itemindent{32pt}\item[a)] This is the answer a), which 
                                      is not true unless you know it is.}
\itemsep0em
{\setlength\itemindent{32pt}\item[b)] This is the answer b), which 
                                      is not true unless you know it is.}
\itemsep0em
{\setlength\itemindent{32pt}\item[c)] This is the answer c), which
                                      is not true unless you know it is.}
\itemsep0em
{\setlength\itemindent{32pt}\item[d)] This is the answer d), which
                                      is not true unless you know it is.}
\itemsep0em
{\setlength\itemindent{32pt}\item[e)] This is the answer e), which
                                      is not true unless you know it is.}
\end{enumerate}

The big problem is that the text of each possible answer of the multiple choices, after the identifying letter, is not indented with respect to the letter. In other words, I get:

a) This is the answer a), which
is not true unless you know it is.

While what I really want is:

a) This is the answer a), which
   is not true unless you know it is.

Does anyone knows how to do this? I've searched for previous answers, but none of them dealt directly with the enumerate enviorment.

Thanks in advance!

You probably want to take a look through enumitem's documentation. That will cut out a ton of repeated code for your list formatting:

\documentclass{article}
\usepackage{enumitem}
\usepackage{lipsum}

\begin{document}

\setlist[enumerate]{noitemsep}
% uncomment the line below to align first-level enumerated lists along the
% left margin
% \setlist[enumerate,1]{leftmargin=*}
\setlist[enumerate,2]{label={\alph*}),leftmargin=0em}
% aligns second-level enumerated lists with the first-level enumerated lists

\lipsum[1]
\begin{enumerate}
\item Select one of the following:
\begin{enumerate}
\item This is the answer a), which is not true unless you know it is. This is
      the answer a), which is not true unless you know it is.
\item This is the answer b), which is not true unless you know it is. This is
      the answer b), which is not true unless you know it is.
\end{enumerate}
\end{enumerate}

\end{document}
