Strengthen With Necessary can be Strengthen with sufficient

Hi Mazen, This is actually not uncommon. Quite a few necessary assumption questions have a correct answer that is also a sufficient assumption. As weird as this seems it does actually make sense. A necessary assumption is something the author must believe in if their argument holds true. A sufficient assumption is one that fully makes the argument valid. I think that in almost every case, the author must believe that the thing that would make their argument valid is true.

Thank You Emil.
