Q: The answer to the question: What is the first name of the person who, with her husband, had 3 of their 18 children sruvive into adulthood? is inside the article: Barbara Holper was the daughter of Hieronymus Holper, under whom Albrecht the Elder served his apprenticeship as a goldsmith. The two men became friends, and when she came of age Holper gave his daughter into marriage when Dürer senior was 40 and she was 15. The couple were compatible, well-matched and fond of each other. Yet their son's writings detail their difficult lives and many setbacks; three of their 18 children survived into adulthood – 17 of whom had been born by the time of this portrait. After her husband died Barbara was destitute and went to live with her son. After she in turn died in 1514, her son wrote "This my pious Mother ... often had the plague and many other severe and strange illnesses, and she suffered great poverty, scorn, contempt, mocking words, terrors, and great adversities. Yet she bore no malice. Also she died hard ... I felt so grieved for her that I cannot express it." Barbara is shown wearing a red dress and a matte white bonnet which fully covers her hair, indicating her marital status. Her headdress is draped with a long scarf or train which stretches down her neck and across her left shoulder, contrasting in colour and shape against the black head-wear of her husband. The lines of her face contain touches of white paint to give a highlighting and enlivening effect; they are especially evident around her eyes, the bridge of her nose and around her upper lip. Barbara was attractive in her youth; her son described her as having been "comely and of erect bearing". However, by the time of this portrait the effects of time and losing so many children weigh heavily on her face. The panel was grounded with white paint, while the composition seems to have changed significantly from the  imprimatura. Faint traces of the original figuration are visible in parts of the background and in the darkened areas of her hood. At some point the panel was cut down at the left side, shifting the compositional balance and removing a portion of her shoulder and headdress., can you guess it ?
A: Barbara

Q: The answer to the question: What is the first name of the person that tries out his father's fishing rod? is inside the article: It's Christmas Eve and Richie Rich, the world's richest kid, is all excited to spend the day with his friends. While racing wildly with his friends in the snow, Richie's butler, Herbert Cadbury, controls the cars using a remote and guides the children back to Richie's house. He then reminds him about his responsibilities that are due to be executed on Christmas Eve, and instructs him to change his clothes and get ready for tea. Before going to do so, he visits his home scientist, Professor Keanbean, who shows him his recent invention, a wishing machine which works only on Christmas Eve. The day being that, Richie wishes for a "big pie" from it, and is given a "pig sty" instead. Cadbury is disgusted seeing this, and sends him off to change his clothes. He meets his parents, Richard and Regina Rich, to ask what they would like to have for Christmas. While with them, he also tries out his father's new fishing rod invented by Keanbean, which hooks on to a tuna sandwich in the vicinity. He then goes on to change his clothes. During tea, Richie meets his spoiled cousin, Reggie Van Dough, who wishes that he was as rich as Richie. Later, he dresses up like an elf with Cadbury as Santa Claus to distribute Christmas presents to the orphanage. While getting ready, Cadbury tells Richie about how he was a rock star in his youth days, in a band called Root Canal. When they take off in the sleigh with Richie driving it, Reggie takes control of it using the remote invented by Keanbean that Cadbury used earlier. He guides it through streets by shops, houses, and people, thus nearly destroying everything in the whole process. Richie and Cadbury end up in an accident in which the sleigh falls and literally explodes along with the presents, while Cadbury hurts his ankle badly. Richie runs off to fetch help, but once he enters the city, he sees that the situation has changed dramatically. Reggie is cooking up rumors about him, and all the people have turned against him., can you guess it ?
A: Richie

Q: The answer to the question: What has advantages over land-based mining? is inside the article: The seabed contains enormous reserves of minerals which can be exploited by dredging. This has advantages over land-based mining in that equipment can be built at specialised shipyards and infrastructure costs are lower. Disadvantages include problems caused by waves and tides, the tendency for excavations to silt up and the washing away of spoil heaps. There is a risk of coastal erosion and environmental damage. Seafloor massive sulphide deposits are potential sources of silver, gold, copper, lead and zinc and trace metals since their discovery in the 1960s. They form when geothermally heated water is emitted from deep sea hydrothermal vents known as "black smokers". The ores are of high quality but prohibitively costly to extract. Small scale mining of the deep sea floor is being developed off the coast of Papua New Guinea using robotic techniques, but the obstacles are formidable.There are large deposits of petroleum, as oil and natural gas, in rocks beneath the seabed. Offshore platforms and drilling rigs extract the oil or gas and store it for transport to land. Offshore oil and gas production can be difficult due to the remote, harsh environment. Drilling for oil in the sea has environmental impacts. Animals may be disorientated by seismic waves used to locate deposits, probably causing the beaching of whales. Toxic substances such as mercury, lead and arsenic may be released. The infrastructure may cause damage, and oil may be spilt.Large quantities of methane clathrate exist on the seabed and in ocean sediment at a temperature of around 2 °C (36 °F) and these are of interest as a potential energy source. Some estimates put the amount available at between one and 5 million cubic kilometres (0.24 to 1.2 million cubic miles). Also on the seabed are manganese nodules formed of layers of iron, manganese and other hydroxides around a core. In the Pacific these may cover up to 30 percent of the deep ocean floor. The minerals precipitate from seawater and grow very slowly. Their commercial extraction for..., can you guess it ?
