Hello,
I am a native English speaker, born and raised in England. I have a distinction level master's degree in politics and have written too many essays to remember. Currently, I am working for a thinktank where I have to pen long and complicated political journalism pieces, and so, I am confident in my proof-reading abilities.
I see that you are from Argentina, hablo un poco espanol, so I think it may be a little easier for me to understand any grammar problems which you may face.
What is the text about?
