Indenting text from '\enumerate'

Question

I am trying to write a document that has the same question in two places. So, I've written that question down in a seperate tex file, and used the \input command in both places to copy the question.

However, the question has parts (a, b, c) and I would like each part to have its own, seperate tex file. Once I have done so, I used the \input command twice, once for the original quetsion, and the second for the respective part.

Here is the minimal main.tex file used in this project:

\documentclass[12 pt]{book}
%____________________________Packages____________________________________
\usepackage{import} % For large project management
\usepackage[shortlabels]{enumitem} % For enumeration and lists
\usepackage[margin=1 in]{geometry} % Adds 1 inch margins 

%___________________________Page Style_______________________________________________
\setlength{\parindent}{0cm} % Removes all indentation
\newcommand{\tab}{\hspace*{1cm}}
% __________________________________Body__________________________________
\begin{document}    

\include{Problem_1a}

\end{document}

Here is what Question_1.tex file contains:

\begin{enumerate}
  \item[1.]
  Some question \#1.
\end{enumerate}

Here is what Question_1a.tex file contains:

\begin{enumerate}
    \item[a.]
    Some part 1a.
\end{enumerate}

And, finally, here is the code in question, contained in Problem_1a.tex:

\import{./}{Question_1}
% \tab\import{./}{Question_1a}
\tab{}\input{Question_1a}

\textit{Solution.}
\newline

which generates:

However, the '\input' command (also the \import command) seems to create a new line automatically, and even if I put a '\tab' command (that I've written as a macro) it will skip that line and create another.

This is how I want the final result to look like.

But that was only accomplished manually by:

\begin{enumerate}[1.]
    \item 
    Some question \#1.
    \begin{enumerate}[a.]
        \item 
        Some part 1a.
    \end{enumerate}
\end{enumerate}

How do I force the input command to indent the text it contains (also without creating additional space)?

Note: I don't want to use \input{Question_1a} within Question_1.tex because I want to use Quesiton_1.tex seperatley elswhere within the document.

Answer 1

Instead of trying to force the text from the \input command to be indented, I was able to use the enumerate environment within Question_1a.tex to make it appear as if it was indented. The Question_1a.tex was modified to be:

\begin{enumerate}[\empty]
    \item 
    \begin{enumerate}
        \item[a.]
        Some part 1a.
    \end{enumerate}
\end{enumerate}

This produced the output:

as desired.

I'm guessing there is a better enviroment that is more suited to create this indentation, so if anyone knows of it, let me know in the comments.
