I don't understand it either. I like this course, but I would like it more if it had sentences that made more sense. I get that it's just been produced, but you'd think they'd make more relevant sentences in the first place. This is so vague and makes it hard to remember the verb since it has no context whatsoever.
Could refer to clay sculptures. My first impression was it referred to the children of working parents who are left in the care of nannies during their formative years, but maybe that's not how to use dibentuk
I think your first impression is right because another sentence is 'anak-anak dibentuk oleh keluarga mereka', children are shaped by their families
Other possible english words for dibentuk = formed, molded. The sentence definitely needs some changes though. It is strange. Definitely needs more context to make more sense.
