Me gusta esta historia porque soy un granjero!

Am I correct in understanding that the use of Unos/as is for countable nouns (pears, sunglasses, cellphones... etc)? For non countable nouns such as money, salt, or sugar, you would use a different word to say some?

Rafael y Julio son unos chicos muy deportistas? could you please explain why not Rafael y Julio son unos chicos muy deportistes?  since Rafael y julio are boys ?

I understand your explanation of the usage of this pair, but cannot relate them to the sentences that you set and so consequently keep getting marked wrong. It is very unlikely that I will ever do much writing in Spanish, so it is not very important to me. Unfortunately, the consequence of getting them wrong means that you keep on setting new ones on the same subject. A vicious circle. Can you please stop setting them for me so that I can move on and learn new things. The same applies to que/qué

In another unrelated lesson, a quiz sentence states, 'No me queda mucho dinero pero tengo para dos cervezas más.'  Where does this sentence fit in the various meanings of quedar, as explained in this lesson?

Is this common usage in both spoken and written Spanish? Is it more common in Spain than in Latin America? (i.e. Will there be raised eyebrows if I use it in Mexico, like there often are when I use "cover?") Thanks!
