Spanish language Q&A Forum

On two occasions the text moved on before I could submit my answers and on another occasion it didn't let me submit an answer as I had maybe pressed a key which triggered the "Not sure about that one?" response. 

Hello,

Can you please explain why in this exercise it is only correct to use preterito imperfecto in the third sentence: Teníamos que conseguir muchos puntos para acceder al tesoro escondido - even though the story starts in the indefinido tense. A few sentences later it jumps again to indefinido: Este juego nos ayudó a ser pacientes - while the rest of the sentences are in the imperfecto tense.

Thank you :)

If the following is true:

Bear in mind that used as adjectives, the hundreds must agree with the noun they accompany: 

Había veinte mil trescientas personas en el concierto.

There were twenty thousand three hundred people at the concert.

Then why is the following the opposite?

Ciento is invariable and doesn't have to agree with the noun it accompanies, for example:

Ciento treinta y cinco mil casas

One hundred and thirty-five thousand houses

Why is it 'como se llama' or 'como se llama usted' - not 'como te llama'?

This lesson is a little confusing because under "Examples and Resources", el Preterito Perfecto is shown, after being told above that el Preterito Indefinido is preferred in Latam.  

I use the app SpanishDict to help me check myself on certain concepts, especially on conjugations. For this concept, the gerund, the app uses past and present participles. Frankly, I did not receive a whole hell of a lot of instruction when it came to the difference between a participle and a gerund when I was younger but hey, I turned out ok! I have gotten the gist but the two things don't do the same thing  in Spanish as they do in English. I asked a Spanish professor friend of mine about this and he said one of them  (I can't remember which) was the gerund and the other is the participle. Is he correct? I got a questions wrong because I typed one form but it was actually the other. Also, is SpanishDict throwing me off?
