Spanish language Q&A Forum

I am a bit confused here. Below are two responses which I got wrong. In both cases the "hint" is that it is a "future idea". So why should one of them be indicative and the other subjunctive? "Even if you don't want to" I put in the subjunctive because there seemed to be a bit of doubt, and that was marked wrong. "Even if you do extra hours" I put in the indicative because it seemed that that was definitely going to happen.

I think this is a very complicated and nuanced piece of grammar so I would appreciate some help, thank you.

PS I tried to include a screenshot of my answers but the system wouldn't let me.

Hello, why is the imperfect used in this sentence since knocking on the door is a single event?  Why not "fuimos" ?

Eramos nosotros los quien llamamos a la puerta

sorry about the accents

This is a good concise explanation, but having more targeted practice opportunities would help me progress in this area. 

I believe that according to RAE, the vosotros form of both verbs should have a tilde – creáis.

This problem is in addition to the yo form problem others have mentioned.

In my experience, and according to my dictionary, reflection (in a mirror or an observation) is el reflejo, unless it is the action in physics of something bouncing of something else

In the first sentence, it sounds like the reader skips the word "hacer". Did I miss it even though I replayed it several times?

Since The main differences between ser and estar include that ser is used for permanent qualities, like your name, your place of origin, and your physical appearance, while estar is used to talk about temporary situations, such as how you’re feeling right now or your location.

So why is SER used in this sentence:  Tú eras muy bueno.  - the person that you are talking to is not always good so it is not a permant state.

Ditto in the following sentence.  You are not always rich so why use SER in the following:  Vosotros erais ricos.
