Problem: A friend asked me to answer this question: What mine's shafts were both 590 meters deep?, using the article: SenghenyddSenghennydd in Welshis situated at the northern end of the Aber Valley, approximately four miles (6.4 km) north-west of Caerphilly and eleven miles (18 km) north-west of Cardiff. When geological surveys for coal began in 1890 it was a farming hamlet of around 100 people. Coal was found, and sinking of the first mineshaft for Universal Collierywhich was owned and developed by William Lewisbegan in 1891; the first coal was extracted in 1896. The colliery's two shafts were both 1,950 feet (590 m) deep, the downcast Lancaster and the upcast York. Development of the pit coincided with the Boer War, and sectors of the underground workings were named after key places in the war, such as Pretoria, or the lifting of the sieges at Ladysmith, Mafeking and Kimberley. South Wales miners, including those at Universal, were paid on a rate determined by the Sliding Scale Committee, which fixed wages on the price coal fetched at market. When the price of coal slumped in the late 1890s, low wages led to industrial unrest and, in 1898, a strike that the men at Universal joined at the end of April. The Monmouthshire and South Wales Coal Owners' Association refused to replace the scale, and the strike ended on 1 September with some small concessions granted by the owners. The colliery resumed production and in 1899 was producing 3,000 long tons (3,400 short tons) of coal a week.The industrial historians Helen and Baron Duckham consider Universal Colliery to have been "an unlucky mine". At approximately 5:00 am on 24 May 1901 three underground explosions occurred as the night shift was exiting the pit. Because the explosion damaged the pit winding gear, it took time to clear the debris from the pithead to allow rescuers to begin work. They descended at 11:00 am and rescued one man, an ostler, found alongside the corpse of the horse he was tending. There were no other survivors and 81 men died. Although the funerals for the victims started four days later, the rescue and recovery operations lasted for six weeks.The..., what would be the answer ?

A: Universal Colliery

Problem: A friend asked me to answer this question: What is the nickname of the guide that joined the United States Exploring Expedition whose name is not recorded?, using the article: The United States Exploring Expedition led by Lieutenant Charles Wilkes was tasked with a vast survey of the Pacific Ocean starting in 1838. In September 1840 they arrived in Honolulu, where repairs to the ships took longer than expected. Wilkes decided to spend the winter in Hawaii and take the opportunity to explore its volcanoes while waiting for better weather to continue the expedition. King Kamehameha III assigned American medical missionary Dr. Gerrit P. Judd to the expedition as a translator.Wilkes sailed to Hilo on the island of Hawaii and decided to climb Mauna Loa first, since it looked easier than Mauna Kea. On December 14 he hired about 200 porters, but after he left he realized only about half the equipment had been taken, so he had to hire more Hawaiians at higher pay. When they reached Kilauea after two days, their guide Puhano headed off to the established Ainapo Trail. Wilkes did not want to head back downhill so he blazed his own way through dense forest directed by a compass. The Hawaiians were offended by the waste of sacred trees which did not help morale. At about 6,000 feet (1,800 m) elevation they established a camp called "Sunday Station" at the edge of the forest. Two guides joined them at Sunday Station: Keaweehu, "the bird-catcher" and another whose Hawaiian name is not recorded, called "ragsdale". Although Wilkes thought he was almost to the summit, the guides knew they were less than halfway up. Since there was no water at Sunday Station, porters had to be sent back ten miles (16 km) to a lava tube on Ainapo Trail which had a known supply. After an entire day replenishing stocks, they continued up to a second camp they called "Recruiting Station" at about 9,000 feet (2,700 m) elevation. After another full day's hike they established "Flag Station" on December 22, and by this time were on the Ainapo Trail. Most of the porters were sent back down to get another load., what would be the answer ?

A: ragsdale

Problem: A friend asked me to answer this question: How does the dancer know Clay?, using the article: A musician named Dixie Dwyer begins working with mobsters to advance his career but falls in love with the girlfriend of gangland kingpin Dutch Schultz. A dancer from Dixie's neighborhood, Sandman Williams, is hired with his brother by the Cotton Club, a jazz club where most of the performers are black and the customers white. Owney Madden, a mobster, owns the club and runs it with his right-hand man, Frenchy. Dixie becomes a Hollywood film star, thanks to the help of Madden and the mob but angering Schultz. He also continues to see Schultz's moll, Vera Cicero, whose new nightclub has been financed by the jealous gangster. In the meantime, Dixie's ambitious younger brother Vincent becomes a gangster in Schultz's mob and eventually a public enemy, holding Frenchy as a hostage. Sandman alienates his brother Clay at the Cotton Club by agreeing to perform a solo number there. While the club's management interferes with Sandman's romantic interest in Lila, a singer, its cruel treatment of the performers leads to an intervention by Harlem criminal "Bumpy" Rhodes on their behalf. Dutch Schultz is violently dealt with by Madden's men while Dixie and Sandman perform on the Cotton Club's stage., what would be the answer ?

A:
his brother
