Tekst oryginalny - Japoński - Nan watashi ga shitteiru? chotto matte kudasai......

A bridge for evaluation, please ?

CC: IanMegill2

The first phrase and the last one are Junk Japanese.
The middle phrase means
"please wait a moment"
Literally translated, the whole thing would be:
"Nan I know? please wait a moment...now I am (incomprehensible)...

hummm... The translation I got reads:

"What do I know? Wait a moment.. I'm not well now..."

Should I reject it?

The ungrammatical Japanese is the problem here, not the Brazilian, and the Brazilian you translated into English here could indeed be one suitable translation for the source.
If it were me, I'd approve/validate it.

Thank you, Master
I'll do that
