How do I restore something I deleted off my Facebook wall?

[кαтяιηα]

It wasn't a status update or anything but it was a post from someone from that questions app. They answered 12 questions about me and I hate having that stupid crap all over my wall so I blocked the app and all the questions went away but then I saw that my brother was on my Facebook and all those questions were still there, even though their hidden from my page. How do I restore those questions so I can delete them one by one? Any help would be appreciated. Thanks!

Press the "Account" tab in the top right corner, then click "Privacy Settings." Scroll down until you find Block List. Underneath it will say "Edit your lists of blocked people." Click that, scroll down to Blocked Apps, and Unblock the Questions App. Hope this helped.
