how to force break of long lines

Question

I noticed that some long lines does not break as expected. For example test the following:

\documentclass[12pt,twoside]{article}
\usepackage[a4paper,inner=1.5cm,outer=1.5cm]{geometry}


\begin{document}

here some text here some text here some text here some text here some text here some text here
some text here some text here some text here some text here some text here some text here some
text here some text here some text here some text here some text.

The line that does not break as wanted

\noindent
\fbox{1}~$(x,y,z), (x,y,z), (x,y,z)$;
\qquad
\fbox{2}~$(x,y,z), (x,y,z), (x,y,z)$;
\qquad
\fbox{3}~$(x,y,z), (x,y,z), (x,y,z)$;
\qquad
\fbox{4}~$(x,y,z), (x,y,z), (x,y,z)$ 
\end{document}

If I make the third item just one character longer, for example \fbox{3}~$(x,y,z), (x,y,z), (x,y,z)A$;

Then the line splits correctly. (But if I add my A to the fourth item, then it does not work)

So I would like that a long line would split, even if one piece would result "too short".

Is there some kind of tolerance parameter that I could set for that purpose?

sloppypar may helps you:

\documentclass[12pt,twoside]{article}
\usepackage[a4paper,inner=1.5cm,outer=1.5cm]{geometry}

\usepackage{showframe}

\begin{document}

here some text here some text here some text here some text here some text here some text here
some text here some text here some text here some text here some text here some text here some
text here some text here some text here some text here some text.

The line that does not break as wanted


\begin{sloppypar}
\noindent\fbox{1}~$(x,y,z), (x,y,z), (x,y,z)$;
\qquad
\fbox{2}~$(x,y,z), (x,y,z), (x,y,z)$;
\qquad
\fbox{3}~$(x,y,z), (x,y,z), (x,y,z)$;
\qquad
\fbox{4}~$(x,y,z), (x,y,z), (x,y,z)$ 
\end{sloppypar}
\end{document}

Note that, have added the package showframe just for putting frame
