Only the first word is being spoken in this example.

I know 'para' usually goes in front of verbs in the infinitive form. When does 'por' go in front of verbs in the infinitive form?

While working in a Spanish-speaking school, the kids would say, "Se puede entrar?" to ask if they could enter the class room. The teacher would respond by saying, "Sí, se puede." Why would they use this form? It's like saying, "Can one enter the room?" Is it actually a passive question instead?

In your explanation above under "careful", the original sense used "acabamos con" but the follow-up explanation used "nos acabamos". Are they interchangeable?
