Spanish language Q&A Forum

Seems like I have seen hacer used in sentences like this. For example.  El hizo re hipotecar la casa.  Is this correct? Possible?

It says that the correct answer is  "QUERÍAMOS".  I don't understand why you don't use "quisimos".  We wanted to help and actually did help, so it is a completed action.

Acá se puede usar «del que» o «del cual» también?

"Acordaos que estamos fríendo esta tortilla a fuego lento."

Shouldn't it be "de que"?

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. 

I think the cave that we were going to see pasada mañana is as far from the speaker as from the listeners, and it is far. Caves are usually somewhere outside of a city. So I used aquella and even after I read the lesson I i think that it was the correct answer.

Why isn't "las" used to modify both bicicletas and cintas de correr? I thought bicycles and treadmills were a general class of equipment, and not a specific bike or a specific treadmill. Thank you. 

"Sería tan romántico que mas las diera" is a B2 construction.
