Hello,everyone.I'm learning portuguese with ROSSETA STONE V 3.0.35.I have some questions to ask you.
1. A garçonete está respondendo a uma pergunda.
I don't know if the sentence is right. I think the "a"should be"à".
2.Esse edifíco fica em Nova Lorque.
Esse edifício fica em Barcelona.
Esse edifício fica na Austrária.
I don't tell the difference between "em" and "na".
Me ajuda,por favor.Obrigado!
In the first case, you don't put 'à' because "uma", but, if the sentence it's "A garçonete está respondendo 'à' pergunta", you should put its because of verb "responder" (who anwser a question, it answers to someone)
In the second case, I don't get the rules, but whither I know, it depends of verb and the adjective.
Just it ^^
A garçote está respondendo 'à' pergunta", In this case, you should put "crase" because verb "responder" ("quem responde, responde 'a' alguém").
