Spanish language Q&A Forum

One of the questions for this section was

Yo soy directora en una empresa. (I am a company manager).

Wouldn't it be better to say 

Yo soy directora de una empresa. ?

Above the Q&A form is this statement: This lesson is already in your notebook. Go to your notebook now to kwiz this topic as many times as you like.  When I click to go to my notebook to do the short kwiz again I am not able to do the kwiz again. The opportunity never comes. There is a problem with the program.

In this exercise, what exactly is the reason to prefer "libros buenos" rather than "buenos libros"?

I was informed by my test result that "tantas" was incorrect in this sentence: Mar tiene tantos días de vacaciones como tú.

Why "tantos" and not "tantas"?

Hola Inma,

Please could you advise me?

When speaking casually as in the conversation here, is it generally more common to use 'estar' than 'sentir' regarding 'to feel'?

Gracias :)

Es lo mismo igual que/ tan como, se asemejan y se pueden utilizar.

Tan rojas como las cerezas/ rojas igualnque las cerezas, es el mismo significado, e. El mismo tiempo. 

I’m confused, is there another way to determine when to use a direct or indirect pronoun? Eg, how do you apply “for whom, to whom” in this sentence: 

Me explicó su porqué pero no le creí. She explained her reason but I didn't believe her.
Muchas gracias,Shirley. 

The answer for "the test results" is singular.   But shouldn't it also be plural?  There could be many results for one test.
