Problem: Background: Rivera was born and raised in Long Beach, California, to Rosa Saavedra and Pedro Rivera, who were from Mexico. Her parents raised Rivera and her sister and four brothers in a tight-knit, musical household; her brother Lupillo is also a regional Mexican musician. Rivera spoke both English and Spanish fluently. Her family introduced her to traditional Mexican music, including the genres of banda, nortena, and ranchera.
Context: She began to attain more substantial success with the record Parrandera, Rebelde y Atrevida, released in 2005, which peaked at No. 10 on the Billboard Top Latin Albums chart, since its release it has been certified double-platinum in the Latin field by the Recording Industry Association of America. The second single released from the album, "De Contrabando" became her first and only number--one song to hit the Latin Regional Mexican Airplay in the United States. It is also said to be one of her most known songs.  In 2007, she released Mi Vida Loca, which debuted at number 1 on the Regional Mexican Albums chart and number 2 on the Top Latin Albums chart in the United States, the album garnered an award for Regional Mexican Album of the Year at the 2008 Latin Billboard Music Awards. In a 2011 interview with Billboard magazine she stated, "That was more of Jenni telling her story through music. My life has been so put out there by the media that I figured I might as well put it out there myself, in my own words and through my music. I wanted to clear up speculations about my private life." The album also garnered Rivera her first Lo Nuestro Award for Regional Mexican Female Artist of the Year, an award she would dominate for the rest of her life. The same year she released La Diva en Vivo, a live album that consisted of songs recorded with a mariachi band, which garnered her, her second Latin Grammy nomination for Best Ranchero Album. That year she was the only female singer nominated in that category. The album was recorded at The Gibson Amphitheater in Universal City, California, Rivera sold out the concert which led her to become the first female banda singer to do so. Her tenth studio album, Jenni released in 2008, became her first No. 1 record on the Billboard Top Latin Albums chart in the United States. The album led Rivera to win her second Lo Nuestro Award for Banda Artist of the Year, becoming the first female act to win the accolade. A feat that currently stands to date.  In 2009, she changed course and recorded her first full mariachi studio album titled La Gran Senora, which garnered a Latin Grammy nomination for Best Ranchero Album, it peaked at No. 2 on the Billboard Top Latin Albums chart in the United States. In an interview Rivera said that releasing the album was very daring and marked her career in a positive way, she said she wanted to grow as an artist and the people that listen to banda will listen to mariachi if they find a good album that they feel is worth buying. She went on to say there are certain nationalities that will listen to mariachi and not banda. Those were the people that she was going after. She also stated, "Commercializing a ranchera album is much harder. There had not been a successful female mariachi artist in a long time. It was a big risk, but it was a risk that I was willing to take. La Gran Senora ended up being the biggest-selling [regional Mexican] album of 2010."
Question: How did the album do on the charts?
Answer: which peaked at No. 10 on the Billboard Top Latin Albums chart, since its release

Problem: Background: Maurice Robert "Mike" Gravel (; born May 13, 1930) is an American politician who was a Democratic United States Senator from Alaska from 1969 to 1981 and a candidate in the 2008 U.S. presidential election. Born and raised in Springfield, Massachusetts, by French-Canadian immigrant parents, Gravel served in the U.S. Army in West Germany, and he later graduated from the Columbia University School of General Studies. He moved to Alaska in the late 1950s, becoming a real estate developer and entering politics. He served in the Alaska House of Representatives from 1963 to 1966 and also became Speaker of the Alaska House.
Context: In 1980, Gravel was challenged for the Democratic Party's nomination by State Representative Clark Gruening, the grandson of the man Gravel had defeated in a primary 12 years earlier. Several factors made Gravel vulnerable. As an insurgent candidate in 1968, Gravel had never established a firm party base. Not liking to hunt or fish, he was also always culturally suspect in the state. A group of Democrats, including future governor Steve Cowper, led the campaign against Gravel, with Gravel's actions in respect to the 1978 and 1980 Alaskan lands bills a major issue, especially given that the latter's denouement happened but a week before the primary. The sources of Gravel's campaign funds, some of which came from political action committees outside the state, also became an issue in the contest. Another factor may have been Alaska's blanket primary system of the time, which allowed unlimited voting across party lines and from its many independents; Republicans believed Gruening would be an easier candidate to defeat in the general election.  Gruening won the bitterly fought primary, with about 55 percent of the vote to Gravel's 44 percent. Gravel would later concede that by the time of his defeat, he had alienated "almost every constituency in Alaska."  Gruening lost the general election to Republican Frank Murkowski. Gravel was the last Democrat to represent Alaska in Congress for 28 years, until Anchorage Mayor Mark Begich defeated Stevens, by now an aged, iconic figure who had just been convicted of seven felonies for taking unreported gifts, in a very close and protracted election result in mid-November 2008. (The charges against Stevens were subsequently dropped due to prosecutorial misconduct.)
Question: Why did that happen?
Answer:
As an insurgent candidate in 1968, Gravel had never established a firm party base.
