Normalmente, no hay en una zona residencial. a. casas privadas c. condominios b. departamentos d. fábricas

The answer is D there’s not fábricas in a residential zone

A residential area (zona residencial) is where most of the dwellings (houses and/or buildings) are grouped so that people live there, unlike a commercial or industrial area.

Generally, in those areas, depending on the social status there are condominiums (condominios), private houses (casas privadas) or apartments (departamentos).

Factory-type constructions are not allowed, as they are intended for industrial zones.

Therefore, the correct answer is:

Fábricas

(Factories)

Normalmente, no hay fábricas en una zona residencial

Normally, there are no factories in a residential area

Do you need me to translate or write the facts and opinions of the family union? im sorry i just couldnt tell

For this question, it will be important to use the words "mejor" (better), "lo mejor" (the best), and "lo peor" (the worst). while "mejor" is comparative (you are comparing one thing to something else), "lo mejor" and "lo peor" are superlative (there is nothing else better or worse than what these words are describing - there is no comparison).  you could say something like: la música rap es mejor que la música clásica - que es lo peor - pero la música rock es lo mejor de todas las formas de la música (rap music is better than classical music - which is the worst - but rock music is the best out of all the forms of music).
