The OP's 'Member Type' is 'English Teacher'.This looks like homework to me.
That's true but those links you provided might well have simply given away the answer. We expect learners to do their own research, find their own material and give it a try first. Only after that do we generally start helping in that way.
I agree with you. If the learner don't know how to find a answer or the answer is wrong, the teacher here should give the learner helps or guideline the learner to find a better answer. It seems that you are encourage learner to post their question here and can get a answer from native speakers here. I support you.That's what this Georgian teacher of English who came to us for help was told.
You have to bear in mind that the teachers and native speakers on this site are quite disapproving of all these "Turn this perfectly acceptable active sentence into a totally unnatural passive sentence" exercises. They teach students how to construct sentences they will never need.
Was TheParser doing it in his above post?to turn a perfectly acceptable sentence innto the passive.
