Question: In what year did Ivan write Smrt Smail-age Čengića? Passage:Travelogue writer, brother of more noted Ivan, the writer of the well-known epic Smrt Smail-age Čengića. He attended a German school in his native town, where he was trained to become a blacksmith. Often he indulged into travels (Montenegro, Serbia), and exceptionally in a few occasions to Bosnia. In 1841 he was back to Novi, practicing his craft and agriculture, but also engaging in literature and cultural issues in general. In 1847 he ended up in Vienna, in 1848 again in Bosnia (in Sarajevo, at the court of Fazli-paša Šerifija). At the end of 1848, in a letter addressed to his brothers he says: "I don't know when I shall return home, for I have been, I'm afraid, created for this country. Turks are very fond of me for my prudence, they say, and rayah grows ever more trust in me, and therefrom there is no other outcome but mitre on the head or a stake in the arse". After Sarajevo, Matija went to Istanbul (though the exact dates cannot be ascertained), and according to some legends even further, to Suez and the Egypt. In 1852 Matija was back to Novi, where he settled until growing ill in 1879. He lived a secluded life until the symptoms of mind degeneration have started to show, finally dying in the sanatorium of a well-known psychiatrist Richard von Krafft-Ebing, near Graz, on April 17, 1881.

Question: How many days after the episode aired where Beckett creates a gene therapy did the episode air where Beckett helps the Hoffans develop a drug that kills the Wraith who feeds on humans? Passage:While in the Antarctic outpost in the pilot episode "Rising", Dr. Rodney McKay forces Beckett to sit in an Ancient control chair. Beckett's Ancient gene causes him to accidentally activate a drone weapon zeroing on General O'Neill and Major Sheppard's helicopter, but he manages to stop it. After finding and arriving in the city of Atlantis, Beckett examines a severed Wraith arm that Major Sheppard brought back from the planet Athos. Beckett can provide the first information about Wraith physiology and becomes the chief medical officer in Atlantis. In "Hide and Seek", he creates a gene therapy that emulates the ATA gene in normal humans with a 48 percent success rate. In "Poisoning the Well", Beckett helps the Hoffans develop a drug that kills the Wraith who feed on humans, but the drug has the side effect of killing 50 percent of the human recipients as well. One of the casualties is Perna, a Hoffan woman he has grown attached to. Carson leaves in disgust when the Hoffans decide to disseminate the drug among their people at all costs. In "The Gift", he discovers that Teyla has Wraith DNA in her genetic makeup, which allows her to tap into the Wraith psychic network in this and future episodes. In the second season, Beckett takes up more offworld activities, including one mission where he removes a Wraith tracker from Ronon Dex's spine in "Runner".
