Passage: A professor at a college in California, Dr. Peter Proud, begins to have recurring dreams. In one nightmare, Proud appears to see a man murdered by a woman in a rowboat while he is swimming naked. The murdered man repeatedly cries, "Marcia, don't!"
Proud is haunted by his dreams and seeks medical treatment. He attends a "sleep lab" to try to decipher his dreams. However, the dreams do not register as being dreams; in fact, they do not register at all. One evening while watching television, several of his "visions" play out before him on a local documentary entitled "The Changing Face of America". He sees the arch and the church that have been dominating his dreams, and calls the television station to discover the location. Upon learning that the location of his "visions" is in Massachusetts, Proud and his girlfriend Nora travel there. In Massachusetts, the couple drive from town to town, but are unsuccessful until they arrive in Springfield. It is here that Proud begins to see familiar sights from his dreams, such as the bridge, the church, the Puritan statue, and others. Eventually, Peter locates Marcia, the mystery woman from his nightmares, and befriends her daughter Ann at a local country club.
Marcia is suspicious of Peter and curious about his motives and how he knows so much about her life. Ann and Peter eventually fall in love, to Marcia's disapproval, when she is made aware that Peter Proud is a reincarnation of her deceased husband.
Peter had discovered earlier that by re-enacting his dreams, he would stop having that particular dream/vision. The Lake Dream was his last nightmare to be conquered. The film ends as Peter Proud is drawn to the lake where the original crime was committed years ago, and suffers the same fate he did in his previous life. 
Question: What is the first name of the person that the mystery woman from Peter's nightmares is suspicious of?

Ex Output:
Peter.

Passage: On Christmas Eve in 19th-century London, Fred is sliding on ice on a sidewalk. He meets Peter and Tim Cratchit, sons of his uncle Ebenezer's clerk, Bob Cratchit. When Fred reveals who he is, the boys take off in terror. Fred soon arrives at the counting-house of his miserly maternal uncle, Ebenezer Scrooge. After declining an invitation from his nephew to dine with him on Christmas, Scrooge rejects two gentlemen collecting money for charity. That night, Scrooge reluctantly allows his employee Bob Cratchit to have Christmas off with pay but orders him back all the earlier the day after. Later Bob accidentally knocks off Scrooge's hat with a snowball. Scrooge dismisses Bob and withholds a week's pay to compensate for his ruined hat, also demanding a shilling to make up the difference. Bob spends the last of his wages on food for his family's Christmas dinner. 
In his house, Scrooge is confronted by the ghost of his deceased business partner, Jacob Marley, who warns Scrooge to repent his wicked ways or he will be condemned in the afterlife as Marley was. He tells Scrooge he will be haunted by three spirits.
At one o'clock, Scrooge is visited by the youthful Ghost of Christmas Past, who takes him back in time to his early life. Scrooge is shown his unhappiness when he was left to spend the holidays alone at school, and his joy when his sister, Fran, came to take him home for Christmas. The spirit reminds Scrooge that Fran, dead for some years, is the mother of his nephew. Scrooge is shown his early career in business and money lending as an employee under Fezziwig. 
Question: Who explains that there will be three spirits?

Ex Output:
Jacob Marley.

Passage: Social tensions were exacerbated by the revival of the Ku Klux Klan after 1915. The Tulsa Race Riot broke out in 1921, with whites attacking blacks. In one of the costliest episodes of racial violence in American history, sixteen hours of rioting resulted in 35 city blocks destroyed, $1.8 million in property damage, and a death toll estimated to be as high as 300 people. By the late 1920s, the Ku Klux Klan had declined to negligible influence within the state.During the 1930s, parts of the state began suffering the consequences of poor farming practice. This period was known as the Dust Bowl, throughout which areas of Kansas, Texas, New Mexico and northwestern Oklahoma were hampered by long periods of little rainfall, strong winds, and abnormally high temperatures, sending thousands of farmers into poverty and forcing them to relocate to more fertile areas of the western United States. Over a twenty-year period ending in 1950, the state saw its only historical decline in population, dropping 6.9 percent as impoverished families migrated out of the state after the Dust Bowl.
Soil and water conservation projects markedly changed practices in the state and led to the construction of massive flood control systems and dams; they built hundreds of reservoirs and man-made lakes to supply water for domestic needs and agricultural irrigation. By the 1960s, Oklahoma had created more than 200 lakes, the most in the nation.In 1995, Oklahoma City was the site of one of the most destructive acts of domestic terrorism in American history. The Oklahoma City bombing of April 19, 1995, in which Timothy McVeigh detonated a large, crude explosive device outside the Alfred P. Murrah Federal Building, killed 168 people, including 19 children. For his crime, McVeigh was executed by the federal government on June 11, 2001. His accomplice, Terry Nichols, is serving life in prison without parole for helping plan the attack and prepare the explosive.On May 31, 2016, several cities experienced record setting flooding. 
Question: What is the name of the state that saw its only historical decline in population over a twenty-year period ending in 1950?

Ex Output:

Oklahoma.
