Hola.  Could you please explain why, in the following question, "todo aquel que" is a wrong answer?

________ vinieron el año pasado han vuelto este año.All those who came last year returned this year.(HINT: It refers to people in general both male and female)

Note that in El Futuro Simple, only the 3rd person form habrá is ever used on its own and it means there will be.

I don't understand the meaning of this statement. Can you explain and/or give an example?

Can you use estar para + noun? e.g. Miguel no está para bromas

¿Qué te parece utilizar "podrías pedir" en lugar de "podrías preguntar" en la segunda pregunta de este ejercicio?

It seems to me it is not always the case that se comes from a pronominal verb.

I think not when the situtation is accidental or emotional, right? So a non pronominal verb can accompany se while it is being activated buy these 2 states. In other words in, 

Los niños se nos están haciendo mayores sin darnos cuenta.Our children are growing without us realising.
 hacerse not here,  se only comes from emotional involvement. Or is it always the case? I can see where hacerse means becoming.

For the last sentence, can't we use 'llevar' to talk about time spent doing something? 

Why is creer not the right verb for "she thought that" . Difference between pensar and creer please? 

Would a correct answer to this also be ¿Se deben estudiar más?
