I feel like wanna slap myself

I just have my maths test today, and I finished it in time.  

And then I was thinking.. "HUH? THIS IS A RARE CASE, I FINISHED IT 10 MINUTES BEFORE END!" 

Then I do checking... First Question.... Second Question.... Third Question a).... b) .... ehhhhh~~~ Why question C seems so strange? 

OMG I never read this sentence before! I just accidentally skipped this question! 

OMFG it's 7 marks! 

=___= 30 seconds for me to complete it. 

AND I SCREWED IT. 

I just write till the second line. =__= And I estimate I  can earn 1 mark out of 7 marks from this dumb question.
