can you correct me if I made mistakes ¡¡¡ compare two cities I think that Rio de ganeiro and Buenos aires are the most beautiful cities in latin America , both have funniest people and beautiful places , many people said that Buenos aires is the as insecure as Rio de ganeiro on the other hand beaches in rio de ganeiro are colest than Buenos aires , I enjoy both cities in summer and Rio de ganeiro have the biggest festival and people who lives close proximity can enjoy that party propably I might go to brasil to live that more closely, about how much cost live I think that rio de ganeiro ist more expensive that Buenos aires , although both cities are the best to visit if you enjoy music and try good food.
