Question: Arijit Singh is an Indian musician, singer, composer, music producer, recordist and music programmer. He sings predominantly in Hindi and Bengali, but has also lent his voice to various other Indian languages. Singh is regarded as one of the most versatile and successful singers in the History of Indian Music and Hindi Cinema. At the start of his singing career, he received nominations for the Upcoming Male Vocalist of the Year award at the 2013 Mirchi Music Awards for renditions of "Phir Le Aya Dil" and "Duaa", winning the award for the latter.

Singh has played a great role in the Bollywood singing career of one of his contemporaries today Ash King. Regarding his help King told the Times of India, "When I met Arijit in London through a mutual friend, he wasn't a star singer yet. I knew he'd be big someday. When I came back (to Kolkata) in 2010, Arijit invited me to Mumbai and recommended me to Pritam for the song 'I Love You' and 'Te Amo'. He has been a great motivating force." Singh said in an interview that he would love to serve people through his NGO named "Let There Be Light" which works for the Below Poverty Line (BPL) community. His NGO aims to include activities like bloodbank camp (with proof and records and photographs of all the blood being delivered properly), distribution of clothes, books, stationery, etc. to Below Poverty Line children on a huge scale and seasonal human ground activities. In an interview, he spoke about his desire to work for people. "I try and help people in whichever way I can. I owned an NGO long time ago which is now turned into something which helps the people in whichever way they can. For example, we collected a lot of things for victims of the Nepal earthquake. The biggest problem is that we are not ready for anything bad that happens, be it during disasters or helping people post one. For example, the first earthquake in Nepal happened on 25 April and it took me a while to collect something as basic as matchboxes, candles and so on. People basically are not ready to help others. I firmly feel that we over here need a lot of awareness when it comes to population and at times I even feel bad for the Government."

Question: Villa told a number of conflicting stories about his early life, and his "early life remains shrouded in mystery." According to most sources, he was born on 5 June 1878, and named Jose Doroteo Arango Arambula at birth. His father was a sharecropper named Agustin Arango, and his mother was Micaela Arambula. He grew up at the Rancho de la Coyotada, one of the largest haciendas in the state of Durango.

After Villa successfully captured the strategic prize of Torreon, Carranza ordered Villa to break off action south of Torreon and instead to divert to attack Saltillo. He threatened to cut off Villa's coal supply, immobilizing his supply trains, if he did not comply. This was widely seen as an attempt by Carranza to divert Villa from a direct assault on Mexico City in order to allow Carranza's forces under Alvaro Obregon, driving in from the west via Guadalajara, to take the capital first. This was an expensive and disruptive diversion for the Division del Norte. Villa's enlisted men were not unpaid volunteers but paid soldiers, earning the then enormous sum of one peso per day. Each day of delay cost thousands of pesos. Disgusted but having no practical alternative, Villa complied with Carranza's order and captured the less important city of Saltillo, and then offered his resignation. Felipe Angeles and the rest of Villa's staff officers argued for Villa to withdraw his resignation, defy Carranza's orders, and proceed to attack Zacatecas, a strategic railroad station heavily defended by Federal troops and considered nearly impregnable. Since the colonial era, Zacatecas was the source of much of Mexico's silver, and thus a supply of funds for whoever held it. Villa accepted his staff's advice and cancelled his resignation, and the Division del Norte defied Carranza and attacked Zacatecas. Attacking up steep slopes, the Division del Norte defeated the Federals in the Toma de Zacatecas (Taking of Zacatecas), the single bloodiest battle of the Revolution, with Federal casualties numbering approximately 7,000 dead and 5,000 wounded, and unknown numbers of civilian casualties. (A memorial to and museum of the Toma de Zacatecas is on the Cerro de la Bufa, a key defense point where the Federal Army was entrenched.) Villa's victory at Zacatecas in June 1914 broke the back of the Huerta regime. Huerta left the country on 14 July 1914. The Federal Army collapsed, ceasing to exist as an institution. In August 1914, Carranza and his revolutionary army entered Mexico City ahead of Villa. Civil war between the winners was the next stage of the Revolution.

the Division del Norte defied Carranza and attacked Zacatecas.
