text_A: My dear friend, please forgive me, if I can’t pay you a visit, but since I found someone to carry a message, I’m sending you news on this tape. Here we play football, there’s lots of samba, lots of choro and rock’n'roll. Some days it rains, some days it’s sunny but I want to tell you that things here are pretty dark. Here, we’re wheeling and dealing for survival, and we’re only surviving because we’re stubborn. And everyone’s drinking because without cachaça, everybody succumbs to this squeeze.
text_B: If people survive the squeeze, is cachaça a major reason?
YES.
