dos pequenos problemas in la seccion verde asi, "And both of these categories are considered invariable indifinite pronouns, that is to say, they don't change to agree in gender or number with the noun that are substituying."

indefinite= indefinite

that are substituying  = that they are substitituting for

How does one know if

"Hay un incidente ahí; tendrán que llamar a la policía."

should be translated as

1) There is an accident there; they MIGHT have to call the police (probability)

vs

2) There is an accident there, they WILL have to call the police (statement of fact)

Thanks

 I noticed that " me pregunto cuándo van a llegar" was one of the options in this exercise.  Could I have used "van a llegar' instead of "llegaràn" to express probability

Thanks!

In the kwiz, the sentence is: "La matemática y la aritmética no son lo mismo." I understand that we use "lo mismo" when discussing an abstract idea, but in this case, does the phrase have to match the compound subject and verb, los mismos?
