Spanish language Q&A Forum

A little off topic, but consider:

1. donde, adonde/a donde

2. dónde, adónde/a dónde

and for that matter (or maybe especially for the case of), 

3. quizá, quizás 

Within each group the various options can be used interchangeably. But what factors influence the chosen form? For example do some people tend to use the same form all the time? Do people just randomly use all the forms equally? Do some localities tend to use one form more than others? Is there a pronunciation efficiency issue (similar to y and i  or  o and u, but not a hard-and-fast rule)?

I guess my questions especially apply to quizá versus quizás. 

Fernando ___ a Luisa... In another lesson you said that when naming the person, the "le, les" cannot be omitted. I used "estuvo explicándole" but the right answer is "estuvo explicando." Why? Thanks!

La narradora dice “las pilas” pero el texto dice “la pilas”, y el programa te corrige si escribes “las pilas” en tu transcripción. Me gusta esta expresión que no conocía antes. Creo que ya la entiendo, pero tal vez merezca una pequeña nota. ¡Gracias!

Hi, being back after a few months, I noticed that all example sentences use indicative mood, while the one in the lessons was in subjunctive:

De habérmelo explicado antes, no me hubiera enfadado tanto.

Why isn't this conditional, ... no me habría enfadado tanto?

Question: ¡Estén atentos! means: Pay attention!

I don't see anywhere on the lesson that explains this usage. It seems like it's being used as a command/order.

When do we not use the articles like "en casa" instead of "en la casa"?

Hola, the second last sentence says " Todo esto haría crecer nuestro negocio.". Can it be "Todo esto crecería nuestro negocio."? If it can, what would be the difference between these two expressions? Thank you.
