C.1  Comment 1 is the most unhelpful one because it has lots slang and it can be 
really tricky to read.

C.2  Comment 2 is quite helpful but it is a little bit unnecessary

C.3  Comment 3 is  helpful because it is easy to understand and it has no spelling
errors

C.4 Comment 4 is not very helpful because it has spelling errors and it doesn't say 
who it's too. 

C.5 Comment 5 is probably the best in my opinion because it is detailed, has the 
correct punctuation and easy to read.    

C.6 I think 6 isn't helpful because it doesn't say who its from.   

C.7 7 is really bad because its say only a few words.

C.8 8 is unnecessary and a bit weird
