Answer:
¿Cómo andás?
¿Dónde vivís?
Step-by-step explanation:
The question is:
Which ones are examples of "voseo"?
Where voseo is the use of the word "vos", that means something like "tú" or "usted", but less formal.
Usually, words, where the accent mark are in the last silave, are words related to the voseo.
examples 2 and 4, with the explicit "vos" sound like:
" ¿Vos cómo andás?"
"¿Vos dónde vivís?"
While option 1 is related to "tu"
"¿Tú qué escribes?"
And option 4 may work for both, but ins not really an example of voseo.
