28/04/2021. Good Morning.
I realized that in question 2 the template is wrong. The word TUDO will always be an indefinite pronoun, never an adverb, as it does not modify verbs, adjectives or adverbs. The referred question does not offer any option of correct choice, because in the prayer there is no adverb, which appears in all the options. In conclusion then... a correct option would be: PRONOUN-PRONOUN-CONJUNCTION*-VERB.
*Although the word WHAT is a relative pronoun, it can also function, in some cases, as a conjunction.
In question 3 I don't see 2 prepositions, but only one: “DE”. The word DA is a contraction (preposition + article). But anyway… although I disagree, different interpretations can be considered since there is a preposition within the word.
Finally, in question 5, I see colloquial language, yes. But with the observance of being “regional”, as you did and very well, in question 6 mentioning that the language is colloquial, but preferably “digital”. Or one of the options, in my opinion, would be: Regional language.
