Critical Reasoning (CR) | Re: Editorial: The roof of Northtown Council’s equipment-storage

I feel the statement E says that though the roof was empty it fall down. Which means the construction was so weak that even empty roof collapsed . Otherwise , some people may say that because of heavy load on roof and not because of faulty nails the roof collapsed . So the statement E does help the conclusion , however the problem with this option is that , it do not relate the conclusion with premise .

I would be thankful if you reply to my observation .
