Question: What major river runs through the city where station KNVA is located? Passage 1:The team's first feud was against The Midnight Rockers, whom they defeated for the AWA World Tag Team Championship on March 19, 1988. During their year long title reign, Badd Company would feud heavily with Chavo and Mando Guerrero and the team known as the Top Guns (Ricky Rice and Derrick Dukes). They teamed with Madusa Miceli to face the team of the Top Guns and Wendi Richter at the first AWA PPV, SuperClash III. Both Badd Company's Tag Team Title and Wendi Richter's AWA World Women's Championship were on the line, but since Richter pinned Miceli, Badd Company remained the champions. Diamond and Tanaka's reign ended on March 25, 1989 as they lost to "the Olympians" (Brad Rheingans and Ken Patera). Shortly after losing their titles they split from Page, and had a short feud against each other before wrestling in singles competition until early 1990. Just before moving to the WWF, Diamond teamed with The Trooper Del Wilkes for a short run at the AWA Tag Team Titles against The Destruction Crew (Mike Enos and Wayne Bloom). Diamond and Trooper actually defeated The Destruction Crew, but were not awarded the titles when it was determined that Diamond pinned the wrong person.
Passage 2:Early in the Global War on Terror, Fontes served at US Central Command J5 overseeing issues of political-military cooperation in Afghanistan. In June 2004, she was moved to Combined Forces Command - Afghanistan headquarters in Kabul and served under David Barno as the head of the CJ5 staff for political-military coordination. Her staff was responsible for keeping General Barno "on message", overseeing the policies impacting military operations, and performing liaison work with both the Afghan Ministry of Defense and United Nations Assistance Mission in Afghanistan. At the end of her first year in Afghanistan and following Karl Eikenberry's assumption of command from Barno, Fontes volunteered to lead the Provincial Reconstruction Team (PRT) in Tarinkot. Daniel Green, the political adviser for the PRT, reported that though some Soldiers at the PRT had initial concerns due to her gender, those worries were shortly put to rest. She had been active in engaging with the Afghan people. Green said that Fontes, then a Lieutenant Colonel, pitched in a few hundred dollars of her own money to host a lunch on the PRT for local Afghan leaders. An article in Vanity Fair relates a story that she once refused to depart a meeting with Afghan elders in Chora District under threat of small arms fire, for fear of appearing weak in the face of the Taliban. Green asserts that in early 2006, she survived the first suicide vehicle-borne improvised explosive device attack in Urozgan Province due in part to the device's failure to detonate all of the mortar shells of which it was comprised. She departed Afghanistan in May 2006 to attend the US War College, graduating in 2007. She had been promoted that year to colonel. She was subsequently assigned as the chief of the American Security Assistance Office in Pakistan.
Passage 3:These two stations were once dual affiliates of both The CW and MyNetworkTV since their 2006 debuts: KWKB in Iowa City, Iowa, owned by KM Communications, which carried both The CW (as a primary) and MyNetworkTV (as a secondary), but dropped MyNetwork in September 2011; KNVA in Austin, Texas, owned by LIN Television, was the other, until it dropped the network on October 20, 2009. However, in March 2014, WKTC in Columbia, South Carolina, a locally owned station, switched its main channel's primary affiliation from MyNetworkTV to The CW, retaining MyNetworkTV as a secondary affiliation, making it one of three stations in the country that currently carry both The CW and MyNetwork on the same feed (WKTC would be joined in September 2016 by FTS-owned WPWR-TV in Chicago, licensed to Gary, Indiana, and in July 2018 by WUAB in Cleveland, licensed to Lorain, Ohio, in carrying both netlets on their primary channel). In addition, WTVY in Dothan, Alabama, a CBS affiliate owned by Gray Television, now carries MyNetworkTV on a digital subchannel which was previously affiliated with UPN, and also added a third digital subchannel for The CW. WTOK-TV in Meridian, Mississippi, also owned by Gray, has added a secondary MyNetworkTV affiliation to its then-Fox-affiliated digital subchannel and added another digital subchannel for The CW, in addition to ABC on its main channel.
