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.

Q: Passage: In Reno, Nevada, Roslyn Tabor is a 30-year-old woman who has just filed for a quickie six-week divorce from her inattentive husband Raymond. After leaving the Washoe County Courthouse, Roslyn ignores Raymond's attempts to talk to her, and meets with her best local friend and landlord, Isabelle Steers, who is also a divorcee. Isabelle takes Roslyn to a bar at Harrah's Reno for drinks to let the reality of her divorce sink in. While there, they meet an aging cowboy named Gaylord 'Gay' Langland and his tow truck driver friend Guido. They invite Roslyn and Isabelle to Guido's old house in the Nevada country to help her forget about the divorce, after Gay tells Roslyn that he is also divorced. They arrive at the unfinished house Guido built for his late wife, who died several years earlier during childbirth. They drink and dance. Roslyn has too much to drink, so Gay drives her home to Reno.
Eventually, Roslyn and Gay move into Guido's half-finished house and start to work on it. One day after breakfast, Gay tells Roslyn how he wishes he were more of a father to his own children, whom he has not seen for some years. Later that afternoon, Roslyn and Gay argue when Gay states his intention to find and kill the rabbits which have been eating the vegetable garden they planted outside Guido's house. 
Question: What are the first names of the people who arrived at the unfinished house?

A: Roslyn.

Q: Passage: Martin's first recording session with the Beatles took place at EMI's Abbey Road Studios in London on 6 June 1962. Martin immediately complained to Epstein about Best's poor drumming and suggested they use a session drummer in his place. Already contemplating Best's dismissal, the Beatles replaced him in mid-August with Ringo Starr, who left Rory Storm and the Hurricanes to join them. A 4 September session at EMI yielded a recording of "Love Me Do" featuring Starr on drums, but a dissatisfied Martin hired drummer Andy White for the band's third session a week later, which produced recordings of "Love Me Do", "Please Please Me" and "P.S. I Love You".Martin initially selected the Starr version of "Love Me Do" for the band's first single, though subsequent re-pressings featured the White version, with Starr on tambourine. Released in early October, "Love Me Do" peaked at number seventeen on the Record Retailer chart. Their television debut came later that month with a live performance on the regional news programme People and Places. After Martin suggested rerecording "Please Please Me" at a faster tempo, a studio session in late November yielded that recording, of which Martin accurately predicted, "You've just made your first No.1."In December 1962, the Beatles concluded their fifth and final Hamburg residency. By 1963, they had agreed that all four band members would contribute vocals to their albums – including Starr, despite his restricted vocal range, to validate his standing in the group. Lennon and McCartney had established a songwriting partnership, and as the band's success grew, their dominant collaboration limited Harrison's opportunities as a lead vocalist. Epstein, in an effort to maximise the Beatles' commercial potential, encouraged them to adopt a professional approach to performing. Lennon recalled him saying, "Look, if you really want to get in these bigger places, you're going to have to change – stop eating on stage, stop swearing, stop smoking ..." Lennon said: "We used to dress how we liked, on and off stage. He'd tell us that jeans were not particularly smart and could we possibly manage to wear proper trousers, but he didn't want us suddenly looking square. He'd let us have our own sense of individuality.". 
Question: What is the name of the band whose television debut was a live performance on the news programme People and Places?

A: the Beatles.

Q: Passage: The impact would have caused a megatsunami over 100 metres (330 ft) tall that would have reached all the way to what are now Texas and Florida. The height of the tsunami was limited by the relatively shallow sea in the area of the impact; in deep ocean it would have been 4.6 kilometres (2.9 mi) tall. A cloud of super-heated dust, ash and steam would have spread from the crater as the impactor burrowed underground in less than a second. Excavated material along with pieces of the impactor, ejected out of the atmosphere by the blast, would have been heated to incandescence upon re-entry, broiling the Earth's surface and possibly igniting wildfires; meanwhile, colossal shock waves would have triggered global earthquakes and volcanic eruptions. Fossil evidence for an instantaneous die-off of diverse animals was found in a soil layer only 10 centimetres (3.9 in) thick in New Jersey some 5,000 kilometres (3,100 mi) away from the impact site, indicating that death and burial under debris occurred suddenly and quickly over wide distances on land.The emission of dust and particles could have covered the entire surface of the Earth for several years, possibly a decade, creating a harsh environment for living things. The shock production of carbon dioxide caused by the destruction of carbonate rocks would have led to a sudden greenhouse effect. Over a decade or longer, sunlight would have been blocked from reaching the surface of the Earth by the dust particles in the atmosphere, cooling the surface dramatically. Photosynthesis by plants would also have been interrupted, affecting the entire food chain. A model of the event developed by Lomax et al. (2001) suggests that net primary productivity (NPP) rates may have increased to higher than pre-impact levels over the long term because of the high carbon dioxide concentrations.In February 2008, a team of researchers led by Sean Gulick at the University of Texas at Austin's Jackson School of Geosciences used seismic images of the crater to determine that the impactor landed in deeper water than was previously assumed. They argued that this would have resulted in increased sulfate aerosols in the atmosphere. According to the press release, that "could have made the impact deadlier in two ways: by altering climate (sulfate aerosols in the upper atmosphere can have a cooling effect) and by generating acid rain (water vapor can help to flush the lower atmosphere of sulfate aerosols, causing acid rain)." This was borne out by the results of a drilling project in 2016 which found that sulfate-containing rocks found in the area were not found in the peak ring (the rocks found were from deep within the earth's crust instead), the interpretation being that they had been vaporized by the impact and dispersed into the atmosphere. 
Question: What is the full name of what NPP stands for?

A:
net primary productivity.
