Por qué se dice 'evitar propagar' en vez de 'evitar propagando'

Why is the passage below la instead of lo?  

¿Está viendo la última película de Almodóvar? Sí, la está viendo.

Is he watching the last Almodóvar movie? -Yes, he's watching it.

Still struggling with this (and I can see I am not alone based on some comments, lol). Can I share my thinking and you tell me where I am making my mistake? On the quiz the question was: El policía persiguió al ladrón ________ no lo atrapó. (The policeman chased the thief but he didn't catch him. I went back and forth between "pero" and "sino que" for quite a while!  I thought "pero" would work because it makes a contrast (chased / caught). But, then I noted the change in verbs before and after "but," (persiguio / atrapo) and thus used "sino que." This issue, where I feel a note a second verb is one of the largest reasons I keep getting this wrong. How should I be approaching this differently? Thanks as always for your help! PS - I didn't use proper accents above as when I do my computer kicks me out of this program!

Instead of 'En caso de que tengas un problema...' is it possible to say 'Si tengas un problema...' whilst retaining the same meaning?

I thought you don't need to use the personal a with animals although it's commonly used with pets. Is that so? So couldn't it be "vio los elefantes"?

In this final example, why is it alguno and not algunos in the second sentence. Some in English would never refer to one thing so the English translation and the Spanish don’t seem to match to me. This doesn’t seem to be an example of the point before about “alguna revista” meaning some magazine or things like that.

Don't mix the indefinite adjective algún with the indefinite pronoun alguno. You can never use alguno with a noun!

Why is ser used in the exercise "El hombre fue acusado....." Why not use "El hombre acusó...." Is there a rule or custom about verbs with certain nouns.? 

Small clarification: does cocer actually mean "to boil"?
I thought it meant to cook in a hot water, not exactly "boil". 
If I am wrong then how is it different from hervir?

Thank you in advance.
