 Why is it  hubo fuegos artificiales when fireworks is plural? Why would it not be hubieron fuegos artificiales? 

Hi, just want to let you know that this is the third mini-quiz that I've come across on my recommended list that has no questions.  It just says "1 of 0".

The lesson says, " This happens in one of these two situations. But, it appears from the examples and the quiz that aunque is followed by the preterite imperfect subjunctive only if both a) an action in the past and b) the information is shared by the speaker and the listener.

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.

hi, in the case of saying ´en algún libro´etc where we mean some book, a book non specifically, can we use ´un´ in place of ´algún´?

In the text above, it says, 'no parará de reír.'

But in the exercise it was corrected to 'reirse'

Which is correct?

I think it should be noted that there are some additional adverbs which can be combined with de:

cerca (de)

adelante (de)

arriba (de)

Please confirm/update?
