In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Input: Consider Input: Passage: Elliot Hopper is a workaholic widower who is about to land the deal of a lifetime at work, which he hopes will win him a promotion and a company car. After he forgets his daughter Diane's birthday, he attempts to make it up to her by promising her she can have his car when he secures the deal at work on the coming Thursday. After being persuaded to give the car to his daughter early, Elliot must hail a taxi from work, which is driven by Satanist Curtis Burch, who drives erratically and is of control. Attempting to get the taxi stopped, Elliot announces that he is Satan and commands him to stop the taxi, and also attempts to give him his wallet. Shocked to see his "Evil Master", Burch drives off a bridge and into the river.
Elliot emerges from the accident scene, only to learn that he is a ghost when a police officer fails to notice him and a speeding bus goes straight through him. When he gets home he discovers that his three children can see him, but only in a totally dark room, and they can't hear him at times. He struggles to tell them what happened when he is whisked away to London by paranormal researcher Sir Edith, who tells him he is a ghost who has yet to enter the afterlife because "they screwed up"; his soul will not cross over until Thursday.
The pressures of work and family life lead to many comedic events, as Elliot attempts to renew his life insurance policy and complete his company's merger, so his family will be provided for once he crosses over. One day, he must choose between staying in an important work meeting and helping his son with a magic trick at school. He eventually decides that his family's happiness is more important and walks out on his furious boss, Mr. Collins, who later smugly fires him. Dejected, Elliot reveals himself as a ghost to his love interest, Joan, whose initial shock soon turns to sympathy. 
Question: Who is Elliot Hopper's boss?

Output: Mr. Collins.


Input: Consider Input: Passage: After the Southwest became part of the U.S., explorers continued to look for good east–west routes along the 35th parallel. In 1853, a crew led by U.S. Army Lieutenant Amiel Whipple surveyed along a sandy wash in the northern part of the Petrified Forest. So impressed was Whipple by the petrified wood along the banks of the arroyo that he named it Lithodendron Creek (Stone Tree Creek). Geologist Jules Marcou, a member of the Whipple expedition, observed that the petrified trees were from the Triassic.A slightly later route along the parallel was a wagon road, built between 1857 and 1860, that involved experimental use of camels as transport. In the late 19th century, settlers and private stagecoach companies followed similar east–west routes. Homesteaders who stayed in the area developed cattle ranches on the grasslands, and cattle grazed in the Petrified Forest until the mid-20th century.Also close to the 35th parallel was the Atlantic and Pacific Railroad. Its opening in the early 1880s led to the founding of towns like Holbrook and Adamana. Visitors could stop at the Adamana train station, book a hotel room, and take a tour of what was then called the Chalcedony Forest. Over the years, the line changed hands, becoming the Atchison, Topeka and Santa Fe Railway, and then the BNSF. More than 60 BNSF trains, mostly carrying freight, pass through the park every day. U.S. Route 66, a former transcontinental auto highway developed in 1926 from part of the National Old Trails Road, ran parallel to the railroad tracks until it was decommissioned in 1985. The park has preserved within its boundaries a small grassy section of the road. Interstate 40, which crosses the park, replaced the older highway. 
Question: What road did Interstate 40 replace?

Output: U.S. Route 66.


Input: Consider Input: Passage: At 3:06 pm, on November 13, 1985, Nevado del Ruiz began to erupt, ejecting dacitic tephra more than 30 kilometres (19 mi) into the atmosphere. The total mass of the erupted material (including magma) was 35 million tonnes—only 3% of the amount that erupted from Mount St. Helens in 1980.  The eruption reached a value of 3 on the Volcanic Explosivity Index. The mass of the ejected sulfur dioxide was about 700,000 tonnes, or about 2% of the mass of the erupted solid material, making the eruption atypically sulfur-rich.The eruption produced pyroclastic flows that melted summit glaciers and snow, generating four thick lahars that raced down river valleys on the volcano's flanks. It also destroyed a small lake that was observed in Arenas crater several months before the eruption. Water in such volcanic lakes tends to be extremely salty and contain dissolved volcanic gases. The lake's hot, acidic water significantly accelerated the melting of the ice; this effect was confirmed by the large amounts of sulfates and chlorides found in the lahar flow.
The lahars, formed of water, ice, pumice, and other rocks, mixed with clay as they travelled down the volcano's flanks. They ran down the volcano's sides at an average speed of 60 km per hour, eroding soil, dislodging rock, and destroying vegetation. After descending thousands of meters down the side of the volcano, the lahars were directed into all of the six river valleys leading from the volcano. While in the river valleys, the lahars grew to almost 4 times their original volume. In the Gualí River, a lahar reached a maximum width of 50 meters (200 ft).One of the lahars virtually erased the town of Armero in Tolima, which lay in the Lagunilla River valley. Only one quarter of its 28,700 inhabitants survived. The second lahar, which descended through the valley of Chinchiná River, killed about 1,800 people and destroyed about 400 homes in the town of Chinchiná, in the department of Caldas. In total, over 23,000 people were killed and approximately 5,000 were injured. More than 5,000 homes were destroyed. The Armero tragedy, as the event came to be known, was the second-deadliest volcanic disaster in the 20th century, being surpassed only by the 1902 eruption of Mount Pelée, and is the fourth-deadliest volcanic eruption in recorded history. It is also the deadliest known lahar, and Colombia's worst natural disaster. A young girl named Omayra Sánchez became a worldwide symbol of the disaster after images of her trapped under the debris of her former home, after the eruption made the news worldwide. 
Question: What eruption reached a value of 3 on the Volcanic Explosivity Index?


Output: Nevado del Ruiz.
