In the example, 

El armario es dificil de montar, can you say (difícil a montar)?

Is that acceptable in any situation?

Hello,

I noticed that oler seems to be sometimes built with the preposition "a" before introducing the smell of something, such as in:

Tú hueles a perfume fresco. 

or

Las galletas huelen a chocolate.

So I thought it was used in the meaning of "smelling like something", when the subject themselves smells like something. But then I also noticed it in ¿Vosotros oléis a pollo quemado?".

So is the "a" used rather when the smell has no article? What is the rule (if any)?

Thank you!

Hola!

Solo un FYI, la grabación salta en la tercera frase.

Gracias

With respect to the question "Which of the following masculine adjectives are the same in the feminine form?" which provides six choices, does the lesson provide the necessary information to correctly identify which are the same in their feminine form? I have the sense I am not comprehending exactly what the lesson is trying to tell us.   

(I think I know what the lesson is trying to say now--Would the question above be true if it were stated thus: "Which of the following masculine adjectives remain masculine when used with feminine nouns?")

never mind, I see what I did wrong (i do not see a way to delete a question)

In the test question, "Rafael y Julio son unos chicos muy . . . ," The English translation omits the "some" (unos). I wonder why that was done. Was it to show that "unos" is always added in the given Spanish usage? I would be interested in any corresponding lesson.

Not exactly sure what "These adjectives are always invariable in masculine and feminine singular" is trying to tell me. Does this imply that -e ending nationalities can be either masculine or feminine?

This is an excellent lesson.  Very clearly explained.

I understand the idea of using the imperfect to picture what is happening in the moment.  But there is another tense for this as well.  I forget the name of it, so I will just use an example.

"La profesora abría la puerta."

"La profesora estaba abriendo la puerta."

Would the choice between these two tenses be up to the speaker, or would there be a grammatical rule that tells us which one to use?

Thanks.
