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.
question:
Passage: While diving off the Miami coast seeking one of the eleven fabled Spanish Galleons sunk in 1591, private investigator Tony Rome discovers a dead woman, her feet encased in cement, at the bottom of the ocean.
Rome reports this to Lieutenant Dave Santini and thinks nothing more of the incident, until Waldo Gronski hires him to find a missing woman, Sandra Lomax. Gronski has little in the way of affluence, so he allows Rome to pawn his watch to retain his services.
After investigating the local hotspots and picking up on a few names, Rome soon comes across Kit Forrester, whose party Sandra Lomax was supposed to have attended. Rome's talking to Forrester raises the ire of racketeer Al Mungar, a supposedly reformed gangster who looks after Kit's interests.
Thinking there may be a connection between Lomax, Forrester and Mungar, Rome starts probing into their backgrounds and begins a romantic relationship with Kit. With both cops and crooks chasing him and the omnipresent Gronski breathing down his neck, Rome finds himself deep in a case which provides few answers.
answer:
What is the first name of the man that pawns the watch of the person looking for the missing woman?

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?


question:
Passage: Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American singer, songwriter, and dancer. Dubbed the "King of Pop", he is widely regarded as one of the most significant cultural figures of the 20th century and one of the greatest entertainers of all time. He was also known for his unorthodox lifestyle, residing in a private amusement park he called Neverland Ranch, and often becoming the focus of tabloid scrutiny. Jackson's contributions to music, dance, and fashion, along with his publicized personal life, made him a global figure in popular culture for over four decades. 
The eighth child of the Jackson family, Michael made his professional debut in 1964 with his elder brothers Jackie, Tito, Jermaine, and Marlon as a member of the Jackson 5. He began his solo career in 1971 while at Motown Records, and in the early 1980s, became a dominant figure in popular music. His music videos, including those for "Beat It", "Billie Jean", and "Thriller" from his 1982 album Thriller, are credited with breaking racial barriers and transforming the medium into an art form and promotional tool. Their popularity helped bring the television channel MTV to fame. Bad (1987) was the first album to produce five US Billboard Hot 100 number-one singles. He continued to innovate throughout the 1990s with videos such as "Black or White" and "Scream", and forged a reputation as a touring artist. Through stage and video performances, Jackson popularized complicated dance techniques such as the robot and the moonwalk, to which he gave the name. His sound and style have influenced artists of various genres.
Jackson is one of the best-selling music artists of all time, with estimated sales of over 350 million records worldwide; Thriller is the best-selling album of all time, with estimated sales of 66 million copies worldwide. His other albums, including Off the Wall (1979), Bad (1987), Dangerous (1991), and HIStory (1995), also rank among the world's best-selling. He won hundreds of awards (more than any other artist in the history of popular music), has been inducted into the Rock and Roll Hall of Fame twice, and is the only pop or rock artist to have been inducted into the Dance Hall of Fame. His other achievements include Guinness world records (including the Most Successful Entertainer of All Time), 15 Grammy Awards (including the Legend and Lifetime Achievement awards), 26 American Music Awards (more than any other artist), and 13 number-one US singles (more than any other male artist in the Hot 100 era). Jackson was the first artist to have a top ten single in the Billboard Hot 100 in five different decades. In 2016, his estate earned $825 million, the highest yearly amount for a celebrity ever recorded by Forbes.

What is the first name of the person whose estate in 2016, earned $825 million, the highest yearly amount for a celebrity ever recorded by Forbes?
