Problem: Please answer a question about the following article about 2008 Summer Olympics torch relay:
 United States of America: The torch relay's North American leg occurred in San Francisco, California on April 9. On the day of the relay officials diverted the torch run to an unannounced route. The start was at McCovey Cove, where Norman Bellingham of the U.S. Olympic Committee gave the torch to the first torchbearer, Chinese 1992 Olympic champion swimmer Lin Li. The planned closing ceremony at Justin Herman Plaza was cancelled and instead, a ceremony was held at San Francisco International Airport, where the torch was to leave for Buenos Aires. The route changes allowed the run to avoid large numbers of China supporters and protesters against China. As people found out there would be no closing ceremony at Justin Herman Plaza, there were angry reactions. One demonstrator was quoted as saying that the route changes were an effort to "thwart any organized protest that had been planned." San Francisco Board of Supervisors President Aaron Peskin, a critic of Mayor Gavin Newsom, said that it was a "cynical plan to please the Bush State Department and the Chinese government because of the incredible influence of money." Newsom, on the other hand, said he felt it was in "everyone's best interest" and that he believed people had been "afforded the right to protest and support the torch" despite the route changes. Peter Ueberroth, head of the U.S. Olympic Committee, praised the route changes, saying, "The city of San Francisco, from a global perspective, will be applauded." People who saw the torch were surprised and cheered as shown from live video of CBS and NBC. The cost to the city for hosting the event was reported to be USD $726,400, nearly half of which has been recovered by private fundraising. Mayor Gavin Newsom said that "exponential" costs associated with mass arrests were avoided by his decision to change the route in consultation with police chief Heather Fong.
What is the name of the first North American torchbearer?
A: Lin Li

Hinkley Point C nuclear power station is a project to construct a 3,200 MW two reactor nuclear power station. On 18 October 2010, the British government announced that Hinkley Point – already the site of the disused Hinkley Point A and the still operational Hinkley Point B power stations – was one of the eight sites it considered suitable for future nuclear power stations. NNB Generation Company, a subsidiary of EDF, submitted an application for development consent to the Infrastructure Planning Commission on 31 October 2011. A protest group, Stop Hinkley, was formed to campaign for the closure of Hinkley Point B and oppose any expansion at the Hinkley Point site. In December 2013, the European Commission opened an investigation to assess whether the project breaks state-aid rules. On 8 October 2014 it was announced that the European Commission has approved the project, with an overwhelming majority and only four commissioners voting against the decision.
