Свој and asking чији?
Ten minutes on the topic's other two pieces: свој, used whenever the possessor is the sentence's own subject regardless of person - a husband and a wife each with своју own, never његову/њену - and чији/чија/чије, the question word possessives answer, which agrees with the thing owned exactly like the pronouns themselves. Build sentences with both before choosing and translating your way through the rest.

Свој - the reflexive possessive
Свој refers to something owned by the subject of the sentence, whatever the person: Марко воли своју кућу. (Marko loves his own house.) Use његову кућу if it belongs to another man.
Свој changes like мој/твој and agrees with the thing owned: Ја читам своју књигу.
Чији? - asking whose
Чији/чија/чије (whose) is the question word that possessive pronouns answer, and - like који/која/које in the lesson on questions - it agrees with the gender and number of the thing possessed, not with whoever might own it.
