Spanish language Q&A Forum

I'm not clear on the difference between Quedar and Quedarse when expressing results.  The lesson says to use quedar to emphasize a result, and to use quedarse to express the result of a change.  What's the difference, please?  For instance, the following two examples seem pretty similar to me:

Seguro que quedarás contenta con tu pelado nuevo.
I am sure you will be/end up pleased with your new hair cut.

¡Laura va a quedarse pasmada con la noticia!
Laura will be astonished with the news!

Thanks. 

In the writing challenge we are asked to translate: "The Spanish guitar has 6 strings and consists of a wooden box, a neck and a fretboard". Kwiziq's answer is given as "La guitarra española tiene 6 cuerdas y está formada por una caja de madera, un mástil y un diapasón"  and "está hecha de una caja..." is given as an alternative answer. 

I used consistir en instead of estar formada por  or está hecha de. However, if the sentence had been "The Spanish guitar is made of..." I'm pretty sure I would have gone with está hecha de.

So, is my answer wrong? Or, could my answer be considered a third alternative? And could you explain the differences between the two forms, consistir en and estar formado por/estar hecha de, and in what contexts I might use one in preference to another.

Vosotros quisisteis comprar flores a Manuela.

Hi! In the above sentence, if the flowers were a present, would they buy them "para" instead of "a" Manuela? Just wondering if I'm correct that the "a" makes it more like a service than a present.

la compañía para que yo trabajo es el mejor.
Is this construct normally used in Spanish?

In the quiz, the sentence was :  Vas a ir con ella al teatro.  I know that it doesn't sound quite right to say "Vas a ir consigo al teatro", but why would that be incorrect?

What is the difference among these words: guapo, bonito, precioso, hermoso & bello?

I was confused by the hint given for the first sentence:

Use lo que + verb + subj for emphasis ...

I interpreted "subj" as "subjunctive", and made quite a mess of my answer !

How can you start the lesson with "Antes de que and Antes que are always followed by the subjunctive. For example:"

Then in the last part of the lesson give examples without the subjunctive. That's the opposite of always.
