How to add right answer key at the end of \newpage, created in article with task environment

Question

I'm creating a math test, this is the file I'm using. I like this file, basically I coped this from different latex files, at the beginning, I used the table to input the right keys, this way is too slow and I made a lot of mistakes, I saw some people can fix this use add \CC in front of the right answer or use \correctchoice (in exam), I don't know how to add maybe \renewenvironment.

What style do you want to apply for the item of correct choice? — muzimuzhi Z, Jun 19 '20 at 21:19

I suggest to

use the tcolorbox solution by @Ignasi from the answer here https://tex.stackexchange.com/a/340938/ instead of your implementation of \mybox (which at least needs to get rid of the figure environment;
use my answer with tasks and xsim here https://tex.stackexchange.com/a/577369/ to implement a choices environment and use the exercise environment
use the parskip package

Then we can have a clean input in the document...

\begin{document}
\begin{examtitle}{Test 1}
  Angles in parallel lines
\end{examtitle}
\begin{multicols*}{2}
\begin{exercise}
  If the ratio of two supplementary angles is $\frac{4}{11}$, what is the
  measure of the small angle?
  \begin{choices}(5)
    \choice \ang{36}
    \choice \ang{44}
    \choice \answer{\ang{48}}
    \choice \ang{52}
    \choice \ang{60}
  \end{choices}
\end{exercise}
\begin{exercise}
  .
  .
  .
\end{document}

... and still maintain your desired output:
