"if the answer was 'IDK' "

When you put 4 or more questions in one topic, and even add to the topic with more questions, then you get the answers to those questions. There is no IDK; why would anyone bother to reply they don't even know what to reply with? I gave you lots of resources and answers.

But I warned you that you might not like the answers.

Otherwise, you are Welcome; glad to help.
