(I'll preface this question by saying that there seem to be quite a few question on tex.se with keywords 'align' and 'enumerate', but it seems as if they all deal with questions regarding alignment within the enumerate environment or combining the the align and enumerate environments - so I don't believe that my question is redundant.)
Here's the gist of what I am doing and what issue has come about. I am typing up solutions to a, say, three-part (math) question, the parts being enumerated as (i),(ii), and (iii). After stating each part, I wish to write the solution right underneath. So it should look like
(i) Q
A
(ii) Q
A
(iii) Q
A
Perhaps it's not the most efficient way of typing it up (by all means, feel free to recommend something else) but I've done this as
\begin{enumerate}[(i)]
\item question 1
\end{enumerate}
answer 1
\begin{enumerate}[(ii)]
\item question 2
\end{enumerate}
answer 2
\begin{enumerate}[(iii)]
\item question 3
\end{enumerate}
answer 3
However, the way it comes out has (iii) shifted further right than (ii), which is shifted further right than (i). Can anyone tell me why this happens and how to remedy it?
