Question:
Mana (Spanish: "manna") is a Mexican Rock band from Guadalajara, Jalisco. The group's current line-up consists of vocalist/guitarist Fher Olvera, drummer Alex Gonzalez, guitarist Sergio Vallin, and bassist Juan Calleros. Mana has earned four Grammy Awards, eight Latin Grammy Awards, five MTV Video Music Awards Latin America, six Premios Juventud awards, nineteen Billboard Latin Music Awards and fifteen Premios Lo Nuestro awards.
In 1997, the group released Suenos Liquidos, an album about the highs and lows of love, with songs like "Clavado en un bar" and "En el Muelle de San Blas," recorded in Puerto Vallarta and released simultaneously in 36 countries. The recording received a Grammy Award as Best Latin Rock/Alternative Album. The group performed acoustically in Miami for Latin America's MTV Unplugged program. A final version of the performance was mixed at Conway Recording Studios in Hollywood, and the band released Mana MTV Unplugged on 22 June 1999. In the summer of 1999, the band co-headlined an 18-city tour of the United States with Carlos Santana. Mana also appeared on Santana's 1999 album Supernatural on the song "Corazon Espinado". In 2002, in an effort to blend their sound with that of rock and roll from the sixties and seventies, the band recorded Revolucion de Amor. They won their fourth Grammy for the album. The band released a new version of "Eres mi Religion" for the Italian market in 2003, as a duet with Italian musician Zucchero, and also performed with Zucchero in a new recording of his "Baila Morena". This same year they participated in the annual Pavarotti & Friends concert, along with Queen, Deep Purple, Ricky Martin, Andrea Bocelli, Zucchero and Bono. In 2006, after a four-year hiatus, they released their seventh studio album, Amar es Combatir. It reached #4 on the Billboard Top 200 in its first week, selling over 60,000 copies in the first week. Their first single off the album, "Labios Compartidos", rose to the top of the music charts upon its debut in July, when the group played the song live at the Premios Juventud. Amar es Combatir has sold over 644,000 copies, and the Amar es Combatir Tour in promotion of the album grossed more than $35 million. In 2008, Mana released a live album entitled Arde El Cielo, in both a CD and CD/DVD package. This release shows the band performing during the Amar es Combatir Tour in support of Amar es Combatir.

Question:
Charles Krauthammer (; born March 13, 1950) is an American syndicated columnist, author, political commentator, and former physician whose weekly column is syndicated to more than 400 publications worldwide. While in his first year studying at Harvard Medical School, Krauthammer became permanently paralyzed from the neck down after a diving accident, severing the spinal cord at C5. After spending 14 months recovering in a hospital, he returned to medical school, graduating to become a psychiatrist involved in the creation of the Diagnostic and Statistical Manual of Mental Disorders III, and later developing a career as a Pulitzer Prize-winning writer. He was a weekly panelist on PBS news program Inside Washington from 1990 until it ceased production in December 2013.
Krauthammer criticized President George W. Bush's nomination of Harriet Miers to succeed Supreme Court Justice Sandra Day O'Connor. He called the nomination of Miers a "mistake" on several occasions. He noted her lack of constitutional experience as the main obstacle to her nomination. On October 21, 2005, Krauthammer published "Miers: The Only Exit Strategy", in which he explained that all of Miers's relevant constitutional writings are protected by both attorney-client privilege and executive privilege, which presented a unique face-saving solution to the mistake: "Miers withdraws out of respect for both the Senate and the executive's prerogatives." Six days later, Miers withdrew, employing that argument: "As I stated in my acceptance remarks in the Oval Office, the strength and independence of our three branches of government are critical to the continued success of this great Nation. Repeatedly in the course of the process of confirmation for nominees for other positions, I have steadfastly maintained that the independence of the Executive Branch be preserved and its confidential documents and information not be released to further a confirmation process. I feel compelled to adhere to this position, especially related to my own nomination. Protection of the prerogatives of the Executive Branch and continued pursuit of my confirmation are in tension. I have decided that seeking my confirmation should yield." The same day, NPR noted, "Krauthammer's scenario played out almost exactly as he wrote." Columnist E.J. Dionne wrote that the White House was following Krauthammer's strategy "almost to the letter". A few weeks later, the New York Times reported that Krauthammer's "exit strategy" was "exactly what happened," and that Krauthammer "had no prior inkling from the administration that they were taking that route; he has subsequently gotten credit for giving [the Bush administration] a plan."
