tips:

1 - What was the name of that important figure from Minas Gerais? I can't remember, I think he was a dentist. He fought against a gold tax, I think it was the teeth in the old days. Look, does he have a holiday just for him?

- Information i extracted from google: 21st of april (21, 04 because of how dates in Brazil work)

2 - A very important person in the history of Itajubá, he was a lawyer, I wonder how long it took him to graduate. Did he travel to Europe just to find teachers for a big project? I wonder when this project was consolidated.

- Information i extracted: The person is Teodomiro Carneiro Santiago. 5(?) years to graduate, the big project was the creation of UNIFEI in 1913 (5, 1913) (or maybe 5, 19, 13)

3 - An important man in Brazilian history? Does he even have a historical monument named after him in the city? What's the number of the landmark book he's registered in? Did he marry a woman from Itajuba? When will their wedding anniversary be?

- Information i extracted: The person is Wenceslau Braz. landmark book n° 2, wedding anniversary in 12th of september (2, 12, 09)

All tips together "21, 4, 5, 19, 13, 2, 12, 9" (I think)
