Spanish language Q&A Forum

I am confused by the second sentence of this short paragraph. Why is the article "el" needed (required) before the color names?

Shouldn't it be groupos indígenos with an "o"?

Interesting switch . . . I managed to follow the English audio while thinking Spanish in my head. Bravo! Whether I could recite the Spanish translation while reading it in English is another proposition and i doubt I could do that.

Una dicción muy clara. Un audio excelente y un relato que chido.

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. 

When do you and when you don't use el/la/los/las?

I'm totally confused by this and always end up making the wrong choice. 

"In Spanish, you use hubo whether it is followed by one item or many, unlike in English."

In Preterite, if third person singular is also used for plural, when is third person plural used?

¡Gracias!

Someone else has asked a similar question but in regards to the interchangeability of the tenses, if you were to say "You could have called me the whole evening", can you still say "Podrías/Podías haberme llamado toda la tarde" or do you have to use "Pudiste haberme llamado toda la tarde" because it is in a set time frame now?
