I think, I write and I live

Say, the oral exam is really not OK.
It has been to long for me not to speak in English, especially impromptu speaking.
The speed and the difficulty of this oral exam are alright since I can understand them completely.
However, my mind goes blank right after the questions.
I don't know how to answer them in formal way, with logic and in quick.
For example, there's one question like this" what would you do in the evening when there's no electricity?"
How will you answer this question?
My first thought is to read books to kill time but how can I read without light?
Or should I tell the judges that hey I read with candle light! That's nonsense.
So that's the difficulty for me to respond with logic and without second thought.

I am sorry for the 1200 dollars. I love them but I cant help.
Hey, Jenny,Denise and Rebecca, here I am for the second time to join the exam with you. Dont leave me.
