ふと上記のフレーズを何と言うか気になったので聞いてみました。

SÓ POR CURIOSIDADE,MAS EU QUERO SABER COMO SE FALA PARAGRAFIO SUPRACITADO EM PORTUGUÊS.

Sections 1, 2 and 3 are disconnected from sections 4, 5 and 6.

Notes:

In the section 1:
It looks really hard
might be
It sounds really hard
if the speaker is listening to someone's explanation about it.

In sections 4, 5 and 6,
"Sir" and/or "Mr. OOO"
might be
"Ma'am" and/or "Ms. OOO"
you can't tell in Japanese.

The "Sir" (or "Ma'am") and "Mr. OOO" (or "Ms. OOO") are perhaps the speaker's teachers or doctors, judging from the terms of address used.

If it is really "Ms. OOO," the translation of the fifth and sixth sections should be:

Because she can't read Japanese, she just said it in fun, but it was pretty inappropriate, I must say...

She made a "Portuguese-style joke," but do Brazilians also make similar ones?

In section 6, we don't clearly know from the Japanese WHO said "s/he made a Portuguese-style joke": it could be
You said s/he made....
or even some other person might have said s/he did.
