Spanish language Q&A Forum

I just did an exercise and 'No todavía me he vestido para la fiesta'  was wrong. The correct answer was  'Todavía no me he vestido para la fiesta'.  I don't understand the difference. Help please.

If the example used "Vamos, ..." as "Come on, ...", why cannot I use it in my Quiz answer? Perhaps the Quiz needs to be more modified to remove the multiple correct options and be more concise. 

"Hurry, Run!"  Can I interpret "Hurry" as Command, too? If so, none of the options is appropriate. 

II read in the lesson that eso and ello are mostly interchangable, except when used as a direct object. In that case you must use Eso. But in some sentences where I have used eso it was marked as incorrect in favour of ello.  What am i missing?  I didn't see a rule that said this is when ello is correct and eso is not acceptable.  Thanks

It would really help if the English translations were closer to the answer you're looking for, especially in this lesson where depending on whether you're in Latin America or Spain, people could choose either option and be correct.

This is the question from the quiz that I got wrong:

Hoy no _________________ a nadie interesante.I haven't met anybody interesting today.
I selected "he conocido" because that is the direct translation and it seems like that's what they'd say in Spain due to the timing. But in Latin America (which is my selected profile but I'm not sure that it actually impacts my quizzes or not), it would be "conoci".
If you translated it to "I didn't meet anyone interesting today", that would make sense in English and prompt the correct answer, would it not? Because it seems like based on this lesson, either answer is correct depending on what Spanish-speaking country you're in!
