Consider the following minimal example of the [`alterqcm`](http://altermundus.fr/pages/alterqcm.html) package:

```
\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[upright]{fourier}
\usepackage{alterqcm}

\parindent0pt
\begin{document}
\begin{alterqcm}[lq=8cm,language=english] 
 \AQquestion{Question}{% 
 {Proposition 1},
 {Proposition 2},
 {Proposition 3}}  
\end{alterqcm}

\end{document}  

```

Is there any option such that the spacing between Proposition 1, Proposition 2 and Proposition 3 is more compact like in a `compactenum` environment (using the `paralist` package)?

Is there any way to have globally fine control over this vertical spacing?

**Edit:** 

I tried Werner's answer, however if I want to make the spaces smaller, it seems to have only minimal effect:

```
\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[upright]{fourier}
\usepackage{alterqcm}

\setlength{\parindent}{0pt}
\begin{document}

\begin{alterqcm}[lq=8cm,language=english]
 \AQquestion{Question}{%
 {Proposition 1},
 {Proposition 2},
 {Proposition 3}}
\end{alterqcm}

\bigskip

% =========== FACTOR approach ===========
{\renewcommand{\arraystretch}{0.1}
\begin{alterqcm}[lq=8cm,language=english]
 \AQquestion{Question}{%
 {Proposition 1},
 {Proposition 2},
 {Proposition 3}}
\end{alterqcm}}

\bigskip

% =========== LENGTH approach ===========
{\setlength{\extrarowheight}{-10mm}%
\begin{alterqcm}[lq=8cm,language=english]
 \AQquestion{Question}{%
 {Proposition 1},
 {Proposition 2},
 {Proposition 3}}
\end{alterqcm}}

\end{document}

```
