4. Esteban le pidió a Katarina que se casara con él.
Explanation: Since I understand that you can invent the replies, and since I do not know your level of Spanish, I have tried to use concise sentences, all featuring the "pretérito perfecto simple" or simple past of the verbs <em>ir</em> (to go) and <em>pedir</em> (to ask), since all the questions ask for actions that took place in the past. This tense is used to refer to actions, processes, or states that happened in the past and have already finished when the speaker is talking.
