Different parts of this post are inconsistent each with other and contradict each other.

To make sure, add first 10 multiple choice questions and next 3 multiple choice questions.
You will get 13 multiple choice questions, BUT NOT six multiple choice questions,
as it is announced in the post.

I just answered on this request once - see the link

but you ignored it, as if you did not see it or did not read it or did not understand it (or all of that altogether).

Read your post attentively and try to understand what is written there and why it does not work.
