Sentence rewriting: So surprising, the answer according to my teacher is...

[Duc]

Hello,
Below is an exercise that makes me very confused.
Rewrite sentences:
1.We should do something about it.
So surprising,the answer according to my teacher is ''Something should be done.''
I am not even allowed to use ''about it'' to put into the second sentence.
Please explain it to me.
Many thanks

Hi duc

There is nothing wrong with adding 'about it'.
