Comment: Good job everyone! Prose has been brought down to a more manageable size and in quite a short time I must say. It's good to see the article has so many interested editors willing to help. Having said that, here are some suggestions for further improvement:
 The article still needs some work to fully comply with the Manual of Style. Per Wikipedia:Only make links that are relevant to the context#Dates stand alone years should not be linked. There are several instances of linked years in this article. 
 Also per Wikipedia:Only make links that are relevant to the context words should only be linked if they provide appropriate context for the article. An example of this problem happens in the Economy section where common words such as aircraft, coffee and automobiles are linked. 
 Per WP:DASH date ranges should not use hyphens but rather endashes. This seems to be a problem in citations. 
 In the External links section there's no need to tag English sources as such; this is the English Wikipedia after all. Only tag sources in Portuguese. 
I have some more comments but no more time today. I'll get back on this tomorrow. Good luck,
