ipar can also be sister in law
My brother in laws are from Jakarta. Provided answer was "My brothers-in-law are from Jakarta"
Its a weird thing in English because people say your answer, but the grammatically correct answer is to pluralise the first part, in this case 'brothers'
Ipar can be either male or female, my answer should have been accepted
Wondering how many brothers-in-law he has?
I also did sister in law and was incorrect twice. This needs to be corrected. Either the definition or the answer
