Porque não ganho Inquisitive bage , tenho 31/30 perguntas certas?
(I hope you don't mind me answering in English...)
You can click on the 'Inquisitive' label in your profile, and the popup shows that while you did satisfy the requirement to ask a positively received question on at least 30 days, you still need a so-called 'positive question record':
The FAQ tells what that means:
In order to qualify for any of these badges, you must have a "positive question record", which means you don't have too many Closed, Negative, or Deleted questions overall. The formula is
(TotalQuestions - Negative - Closed - Deleted) / TotalQuestions ≥ 0.5.
