Hi Allen! I am glad to learn from you. 
I have something to tell you about my answer at question9
I got 0.60 mark. 
You commented that my answer looked little copied
I was little shocked because it was my own answer .
So I checked again and I found out why you could not help thinking like that . Actually while I was doing the test, especially question 9 and 10, I wrote my answers on my email at first because my keyboard and screen are so small. So I had to check if there were any errors or not, arrange and modify the answer, and then I copied my answer from my email and posted it agian in the blank of Q9 because I was just worried about "What if it is submitted in the middle of writing ?"In the process of doing so,there must have beenkinda errors in my tablet PC .
 That's why my answer was posted like that. 
Certainly it was my own opinion. I swear! 
So please don't misunderstand me. 
The last text is my corrected answer! If my answer is perfect by itself, Could you please give me perfect score?
