Left margin for 'custom' item of enumeration

I'm recently started making my homework in LaTeX. I'm using the following style.

\begin{enumerate}[leftmargin=0.5cm]
\begin{enumerate}
\item Question
\end{enumerate}
\end{enumerate}


But what happens is that answer "(a)" is aligned all the way to the left, not directly underneath the "(a)" of the question. How can I align it alright? I'm already using the enumitem package.

• Why do you have two nested enumerate environments? – Bernard Feb 16 '14 at 22:26

Is this what you want?

\documentclass{article}
\usepackage{enumitem}
\begin{document}
\begin{enumerate}[label={\textbf{(\alph*)}},leftmargin=0.5cm,align=left]
\item Question
