Spanish language Q&A Forum

There are too many people in my office.

Why is demasiada the correct answer and not demasiadas? Since we're using many in the English sentence. 

Thank you. 

1)hi, could you tell when is molestar used as gustar verb and not,        2)Also in the sentence, the heat annoys me , the spanish translation for this would be ,                                                                    Me molesta el calor,but wont ``the heat`` =lo(dop)                               So the sentence should be , ``me lo molesta``, but why isnt it so on the translators

3)the structure when molestar is used as ``gustar`` is , iop+molestar+subject.Is this an exception?                                                  R there nay other verbs  like this, 

¿Señor Hernandez, ________ otra copa de vino?

I answered "quiere usted" and was marked wrong. It's ok, isn't it?
