Hey, the first context sentence of 増える is:
"ここ2、3年、ビエトが一日に飲むお酒、かなり増えてるんだよね。
“Over the past few years, Viet’s daily amount of alcohol has been considerably increasing.”
I’m not 100% sure but the Japanese sentence seems a bit different to the English translation?
Looks fine to me
Which part are you unsure about? Looks fine to me too.
The tenses, maybe?
(Also, the main clause is broken up by a comma in the Japanese, but not in the English.)
ここ2、３年 - in the last 2 or 3 years (technically slightly different)
ビエトが - Viet (as the subject)
一日に飲む - drunk in one day
一日に飲むお酒 - alcohol drunk in one day = daily alcohol
かなり増えてる - increase significantly
んだ - explanatory のだ
よね - right?/emphasis/flavor
“Viet’s daily alcohol amount has significantly increased in the last 2 or 3 years, right?”
Seems fine
Looks fine here too!
