Hola todos,
in the examples like Nuria has lived in California for 3 months, shouldn't it be: Nuria has been living in California for 3 months to express that it is still ongoing?
In the test I was similarly irritated with the sentence I have lived on a boat for 4 weeks, which I would translate as He vivido en un barco por 4 semanas, but the only option making sense was the one having the form explained in this lesson.
Of course I may be wrong, English isn't my first language.

I would like to practice with possessive adjectives & pronouns, especially with the third person singular and plural

Where, in this rich Qwizik, can I find this kind of exercises ? 

Thanks !

The translation for 

I learned that you can use the futuro simple and the condicional simple to express something which might happen in the future.

Is the difference that the futuro simple only can be used with a sentence which states the probability of the action?

E.g.:

Tú ________ chocolate sin parar

Comerías

Pero:

Probablemente, tú comerás chocolate sin parar.

If my assumption is correct, what is the difference to:

Probablemente, tú comerías chocolate sin parar.
