Hoje em dia (nowadays), it’s pretty common to take a DNA test to figure out who the father is. Watch how in this clip she says, ‘eu faria…’. This just means “i would do it”. In every day conversation the word ‘it’ doesn’t usually get said.

The conditional (would) of the verb FAZER = FARIA.
eu faria
você, ele, ela faria
nos faríamos
vocês, eles, elas faríam
