instruction:
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: As the 19th century progressed, the United States government's Indian removal policy pushed Native American tribes west of the Mississippi River.  In 1830, the Indian Removal Act was signed into law, and though that act did not directly address the Potawatomi people of Indiana, it led to several additional treaties that resulted in their removal.  In what came to be known as the Potawatomi Trail of Death, about 860 Potawatomi Indians who had refused to leave were forced to move from Indiana to Kansas.  On September 14, 1838, the group camped near Williamsport, and on September 15 they camped in the southwestern part of the county before moving into Illinois.  Before reaching their destination in Kansas, over 40 of them had died, many of them children; two children died and were buried at the second Warren County campsite.When the county was established, the Wabash River was vital to transportation and shipping.  Zachariah Cicott traded up and down the river, and cities like Attica, Perrysville, Baltimore and Williamsport were founded near the river's banks and flourished because of it.  In the 1840s, the Wabash and Erie Canal began to operate and provided even broader shipping opportunities, but the canal favored towns which were on the "right side" of the river; the canal was on the Fountain County side, and towns like Baltimore dwindled as a result.  Some towns, such as Williamsport and Perrysville, managed to participate in canal traffic through the use of side-cuts that brought traffic from the canal across the river.  When railroads were constructed starting in the 1850s, they in turn began to render the canals obsolete and allowed trade to reach towns that lacked water connections.  The canal continued to be used through the early 1870s.
answer:
What decade did the canals that provided broader shipping opportunities start to decline due to railroads?

Passage: Beginning on December 11, 1945, Stafford hosted the Tuesday and Thursday broadcasts of NBC musical variety radio program The Chesterfield Supper Club. On April 5, 1946, the entire cast, including Stafford and Perry Como, participated in the first commercial radio broadcast from an airplane. The initial plan was to use the stand-held microphones used in studios but when these proved to be problematic, the cast switched to hand-held microphones, which because of the plane's cabin pressure became difficult to hold. Three flights were made that day; a rehearsal in the afternoon, then two in the evening—one for the initial 6:00 pm broadcast and another at 10:00 pm for the West Coast broadcast.Stafford moved from New York to California in November 1946, continuing to host Chesterfield Supper Club from Hollywood. In 1948, she restricted her appearances on the show to Tuesdays, and Peggy Lee hosted the Thursday broadcasts. Stafford left the show when it was expanded to 30 minutes, making her final appearance on September 2, 1949. She returned to the program in 1954; it ended its run on NBC Radio the following year. During her time with Chesterfield Supper Club, Stafford revisited some of the folk music she had enjoyed as a child. Weston, her conductor on the programme, suggested using some of the folk music for the show. With her renewed interest in folk tunes came an interest in folklore; Stafford established a contest to award a prize to the best collection of American folklore submitted by a college student. The annual Jo Stafford Prize for American Folklore was handled by the American Folklore Society, with the first prize of $250 awarded in 1949.
answer:
What was the name of the person that conducted the Chesterfield Supper Club?


question:
Passage: Although the publicity generated by Five Leaves Left was minor, Boyd was keen to build on what momentum there was. Drake's second album, 1971's Bryter Layter, again produced by Boyd and engineered by John Wood, introduced a more upbeat, jazzier sound.Disappointed by his debut's poor commercial performance, Drake sought to move away from his pastoral sound, and agreed to Boyd's suggestions to include bass and drum tracks. "It was more of a pop sound, I suppose," Boyd later said. "I imagined it as more commercial." Like its predecessor, the album featured musicians from Fairport Convention, as well as contributions from John Cale on two songs: "Northern Sky" and "Fly". Trevor Dann noted that while sections of "Northern Sky" sound more characteristic of Cale, the song was the closest Drake came to a release with chart potential. Cale used heroin during this period, and his older friend Brian Wells suspected that Drake was also using.Boyd and Wood were confident that Bryter Layter would be a success, but it sold fewer than 3,000 copies. Reviews were again mixed: while Record Mirror praised Drake as a "beautiful guitarist—clean and with perfect timing, [and] accompanied by soft, beautiful arrangements", Melody Maker described the album as "an awkward mix of folk and cocktail jazz".Soon after its release, Boyd sold Witchseason to Island Records, and moved to Los Angeles to work with Warner Brothers to develop film soundtracks. The loss of his mentor, coupled with the album's poor sales, led Drake into further depression. His attitude to London had changed: he was unhappy living alone, and visibly nervous and uncomfortable performing at a series of concerts in early 1970. In June, Drake gave one of his final live appearances at Ewell Technical College, Surrey. Ralph McTell, who also performed that night, remembered: "Nick was monosyllabic. At that particular gig he was very shy. He did the first set and something awful must have happened. He was doing his song 'Fruit Tree' and walked off halfway through it."In 1971, Drake's family persuaded him to visit a psychiatrist at St Thomas's Hospital, London. He was prescribed antidepressants, but felt uncomfortable and embarrassed about taking them, and tried to hide the fact from his friends. He worried about their side effects and was concerned about how they would react with his regular cannabis use.Island Records urged Drake to promote Bryter Layter through interviews, radio sessions and live appearances. Drake, who by this time was smoking what Kirby described as "unbelievable amounts" of cannabis and exhibiting "the first signs of psychosis", refused. Disappointed by the reaction to Bryter Layter, he turned his thoughts inwards, and withdrew from family and friends. He rarely left his flat, and then only to play an occasional concert or to buy drugs. His sister recalled: "This was a very bad time. He once said to me that everything started to go wrong from [this] time on, and I think that was when things started to go wrong.".
answer:
What is the last name of the person who agreed to include bass and drum tracks?
