Input: Question: What is the population of the city that the University of Notre Dame is located in? Passage 1:Despite this, Farr was discharged from hospital and sent back to the front with the 1st Battalion of the West Yorkshire Regiment, a part of the 6th Infantry Division, with which he fought in the Battle of the Somme. Farr reported himself to the medical station several times over the following months. In April 1916, he was kept at the medical station for a fortnight due to his state. On 22 July 1916 he spent the night at a medical station and was discharged for duty the following morning. On 17 September 1916 he again attempted to seek the help of a medical orderly, but was refused as he was not physically wounded and the aid station was dealing with a high number of battle casualties. Farr reported for duty at the transport lines at 8 P.M. that evening, but went missing shortly afterwards. Upon being found at 11 P.M., he refused to return to the front line. He was subsequently arrested for disobeying orders, and on 1 October 1916 tried by court martial at Ville-sur-Ancre. He had to defend himself against the formal accusation of 'misbehaving before the enemy in such a manner as to show cowardice'. The Divisional court martial, presided over by Lieutenant-Colonel Frederick Spring, the Commanding Officer of the 11th (Service) Battalion of the Essex Regiment, lasted 20 minutes, and questions have subsequently been raised about its competence. The hearing found Farr guilty and sentenced him to death. General Sir Douglas Haig, as the Commander-in-Chief of the British Expeditionary Force subsequently confirmed the execution order, and Farr was shot by a firing squad made up from men of his own regiment at 6.00 A.M. on 18 October 1916, near Carnoy on the Somme. His family have always argued that he was suffering from shell shock at the time.
Passage 2:"Tobacco", an eighteen-minute segment about the tobacco industry, was delivered by John Oliver on February 15, 2015, during the second episode of Last Week Tonight second season. Oliver introduces the topic of tobacco smoking by showing video clips of "trusted newsmen, cartoon characters, and cowboys in TV commercials" who are smoking cigarettes. He says that the cowboy in the clip is Marlboro Man, a figure used in advertising campaigns for Marlboro cigarettes, and notes that four of the actors portraying Marlboro Man have died from lung cancer or smoking-related illnesses. Oliver says that cigarette smoking is no longer as prevalent in the United States because of, among other things, mandatory warnings on all cigarette boxes and a ban on TV advertisements for cigarettes. The comedian says that tobacco executives adamantly refused to acknowledge the potential drawbacks to smoking, despite strong evidence to prove these drawbacks. He shows a video of Joseph Cullman, the former CEO of the tobacco company Philip Morris International (PMI), saying that "some women would prefer having smaller babies" in response to a reporter's comment that pregnant women who smoke will give birth to smaller babies as a result. Even so, the restrictions on smoking advertisements contributed to a decline in smoking rates among American adults, as only 18% of adults smoked in 2014, compared to 43% of adults in 1965.
