Spanish language Q&A Forum

Hi, there are two questions on the quiz that I don't understand: (1) "Esos chicles son mentolados pero  ____  no tienen sabor" and (2) "Esos estudiantes van a viajar a Asia pero ________ no tienen dinero." Kwiziq is saying that the correct demonstrative pronoun in both cases is "estos." However, my understanding was that demonstrative pronouns should vary in gender with the noun they refer to, unless it isn't known or we are referring to statement, idea, or situation. In 1, the noun being referred to is "chicles," which is a masculine plural noun, so the demonstrative pronoun should be "estes," not estos, correct? With 2, I understand that we may not know the gender of the group, so we use esto. Can you explain?

Do you have se lessons for things like, se me hace, no se te quita, ya no se te nota mucho acento, ya no se les atiende, se percate.  I ask because none of these seem to find homes in the lessons, in order to practice and understand. I mean they are not accidental. Thanks

Hola

In relation to "después de que", I have questions:

(1) why "hallase" (instead of "se halla") is used in this sentence:

"...es el final de un camino [...] después de que la Guardia Civil hallase en la 'tablet' de la víctima un enigmático mensaje."

(2) what construction is this? what are the grammar rules?

Muchas gracias.

I have a question about constructions like this: "Omar y Cristina son nuestros panaderos," e.g. "Omar and Cristina are our bakers." I understand it is "nuestros" because it is the nosotros form of the possessive adjective. However, I'm confused about the gender. Why is it masculine here?

here it says ¨Nosotros no deberíamos haberlo escuchado.¨ Should it be  Nosotros no deberíamos haberle escuchado? Le instead of Lo?

In this question from a quiz:

"El presidente ________ Gobierno tiene su residencia oficial en el Palacio de la Moncloa, en Madrid"

I was told that it should be del. However, in the lesson it says not to use contractions prior to proper nouns. Is this not a proper noun, despite the fact it is capitalized?

Is there any problem with adding "se" to the verb "reír" here? 

Why do we say "ciento por ciento"? Ciento is more than one hundred so shouldn't it only be cien por ciento and cien por cien?
