Passage: 'A series of murders that took place in the East End of London from August to November 1888 was blamed on an unidentified assailant who acquired the nickname Jack the Ripper. Since that time, the identity of the killer or killers has been hotly debated, and over one hundred Jack the Ripper suspects have been named. Though many theories have been advanced, experts find none widely persuasive, and some can hardly be taken seriously at all. Due to the time frame in which the murders took place, and the time that has passed since then, everyone alive at the time is now dead, and despite the killer's identity continuing to be a hot topic of discussion, the killer will likely never be identified.'. Question: 'who is most likely to have been jack the ripper'.
