Task: Question Generation
Input (English): Passage: McVeigh and Nichols purchased or stole the materials they needed to manufacture the bomb, which they stored in rented sheds. In August 1994, McVeigh obtained nine Kinestiks from gun collector Roger E. Moore, and ignited the devices with Nichols outside Nichols's home in Herington, Kansas. On September 30, 1994, Nichols bought forty 50-pound (23 kg) bags of ammonium nitrate fertilizer from Mid-Kansas Coop in McPherson, Kansas, enough to fertilize 12.5 acres (5.1 hectares) of farmland at a rate of 160 pounds (73 kg) of nitrogen per acre (.4 ha), an amount commonly used for corn. Nichols bought an additional 50-pound (23 kg) bag on October 18, 1994. McVeigh approached Fortier and asked him to assist with the bombing project, but he refused.McVeigh and Nichols then robbed Moore in his home of $60,000 worth of guns, gold, silver, and jewels, transporting the property in the victim's own van. McVeigh wrote a letter to Moore in which he claimed that the robbery had been committed by government agents. Items stolen from Moore were later found in Nichols's home and in a storage shed that he had rented.In October 1994, McVeigh showed Michael Fortier and his wife, Lori, a diagram he had drawn of the bomb he wanted to build. McVeigh planned to construct a bomb containing more than 5,000 pounds (2,300 kg) of ammonium nitrate fertilizer, mixed with about 1,200 pounds (540 kg) of liquid nitromethane and 350 pounds (160 kg) of Tovex. Including the weight of the sixteen 55-U.S.-gallon drums in which the explosive mixture was to be packed, the bomb would have a combined weight of about 7,000 pounds (3,200 kg). McVeigh had originally intended to use hydrazine rocket fuel, but it proved to be too expensive. During the Chief Auto Parts Nationals National Hot Rod Association Drag Racing Championship Series event at the Texas Motorplex, McVeigh posed as a motorcycle racer and initially attempted to purchase 55-U.S.-gallon (46 imp gal; 210 L) drums of nitromethane on the pretense that he and some fellow bikers needed the fuel for racing, despite the lack of nitromethane-powered motorcycles at the meeting, and not having an NHRA competitors' license.  Denied by one representative, Steve LeSueur, due to LeSueur's suspicions of McVeigh's actions and attitudes, he was then permitted to purchase three barrels from another representative, Tim Chambers. Chambers questioned the purchase of three barrels when typically only 1–5 gallons of nitromethane, he noted, would be purchased by a Top Fuel Harley rider, even though the class was not raced that weekend.  LeSueur reported the incident to the FBI immediately after rejecting McVeigh's request.
Output (English): What is the last name of the person who did not have an NHRA competitors' license?
