And (1) it is often recommended to use \textit{Solution.}
rather than {\it Solution.} (not so relevant here, rather
with automatical kerning).
More seriously, the enclosing box is twice wider by the
box rule widht and the separator width than the text width,
you get an overfull \hbox warning. To avoid this, before
\fbox should be \leavevmode\kern-\fboxrule\kern-\fboxsep,
and after it there should be \kern-\fboxrule\kern-\fboxsep.
But after that, the box is still too wide, and I must stop
diagnosing now. For boxes around text of full text width,
there are packages like framed and mdframded (and others
I think), I cannot give more advice right now.
Good night,
Uwe.
