The police officer warned the _____ communities against taking the law _____ hands?
Answer Details
The correct option is "feuding / into their own". The sentence means that the police officer warned the communities who were in conflict with each other not to take the law into their own hands. "Feuding" means being in a state of prolonged mutual hostility, especially between families or communities, and "into their own hands" means taking the responsibility to punish someone or do something oneself, rather than leaving it to the authorities.
