Hello, why is the imperfect used in this sentence since knocking on the door is a single event?  Why not "fuimos" ?

Eramos nosotros los quien llamamos a la puerta

sorry about the accents

It would be so much nicer if one didn't need to scroll up and down the page during the exercise. Surely by resizing some of the components on the screen it should be possible to dispense with the need to scroll between each segment of the exercise, no?

Of course, if a cell phone is used that might cause more scrolling etc but on a 14" laptop screen it should be easy enough to presnet a page that's more concise . . .

En la frase "me quedo comtemplándola por horas", debería ser "contemplándola".

You told how not say each person is different.    How do we say it.

or also each dog is different.   or is it just people.

In the beginning of the exercise, you hint at using the word "parientes" for relatives but I think that the word needs to be added to the list of correct answers because currently, you only get a right answer for using "familiares". 

Is there a comprehensive rule for when to use (or not use) PARA before an infinitive? I sometimes encounter examples where para is used without the sense of "purpose" that is supposed to trigger the use of "para."  In other words, I can't use the rule "in order to" to translate these sentences.

Cuándo estaba en Australia, tenía muchos problemas para hablar inglés.

Tuvimos muchas dificultades para encontrar la parada de autobús.

Fue un día demasiado bueno para quedarse adentro.

please help me understand why we use tengo/tiene and not estoy-soy.

Me parece bastante torpe el uso de lo porque sabemos el sujeto. No deja de mostrar que esta institución como la que era, extraordinariamente cruel. (la institución es el sujeto). 😀
