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.

Question: Passage: The crew of a malfunctioning alien cargo ship make an emergency landing on Earth. This draws the attention of four sexually-frustrated humans in a nearby park: Oliver and Prudence (a mild-mannered professional and his highly-strung fiancée), Willy (a bumbling shop assistant) and Cliff (a middle-aged man).
Oliver, Prudence, Willy and Cliff wander into the ship and encounter three aliens resembling human women: engineer Partha, nurse Cosia and the captain, known only as Skipper. Willy inadvertently drops some pornographic magazines that he has recently bought. The aliens mistake some approaching cows for a hostile force and hurriedly take off, despite warnings from the long-suffering computer about the precarious state of the ship's systems. Resuming their original course, they study their guests in detail. Fascinated by the anatomy of the males, they decide to sell them to a zoo for exotic lifeforms on a distant planet. They also debate the significance of the acts depicted in Willy's magazines. Partha is particularly keen to emulate them and enthusiastically has sex with Cliff.
Skipper, Cosia and Partha subject the males to a series of tests to learn more about their abilities. Oliver and Cliff fail miserably. However, Willy, looking for his magazines, beats Skipper's combat simulation by unknowingly evading her attacks, causing her to collapse with exhaustion and infer that he is a stronger being. While conducting a physical examination on Willy, Cosia discovers that his biology is more advanced than anything known to their species; encouraging Cosia with exaggerated claims about his sexual prowess, Willy loses his virginity to her. Later, he passes an intelligence test by a fluke and has sex with Partha. 
Question: Who decides to sell people to a zoo for exotic lifeforms on a distant planet?

Answer: Skipper.


Question: Passage: Johnny Clay is a veteran criminal planning one last heist before settling down and marrying Fay. He plans to steal $2 million from the money-counting room of a racetrack during a featured race. He assembles a team consisting of a corrupt cop, a betting window teller to gain access to the backroom, a sharpshooter to shoot the favorite horse during the race to distract the crowd, a wrestler to provide another distraction by provoking a fight at the track bar, and a track bartender.
George Peatty, the teller, tells his wife Sherry about the impending robbery. Sherry is bitter at George for not delivering on the promises of wealth he once made her, so George hopes telling her about the robbery will placate and impress her. Sherry does not believe him at first but, after learning that the robbery is real, enlists her lover Val Cannon to steal the money from George and his associates.
The heist is successful, although the sharpshooter is shot and killed by a security guard. The conspirators gather at the apartment where they are to meet Johnny and divide the money. Before Johnny arrives, Val appears and holds them up. A shootout ensues and a badly wounded George emerges as the only man standing. He goes home and shoots Sherry before collapsing.
Johnny, on his way to the apartment, sees George staggering in the street and knows that something is wrong. He buys the biggest suitcase he can find to put the money in (and struggles to lock it properly). At the airport Johnny and Fay are not allowed to take the case on their flight due to its size. Instead, they must check it as regular luggage. Johnny reluctantly complies. While waiting to board the plane the couple watch the suitcase fall off a baggage cart onto the runway, break open, and the loose banknotes scattered and then swept away by the backdraft from the aircraft's propellers. 
Question: What are the names of the couple who watch the suitcase fall off a baggage cart onto the runway and break open?

Answer: Johnny Clay.


Question: Passage: Libby's original exchange reservoir hypothesis assumed that the 14C/12C ratio in the exchange reservoir is constant all over the world, but it has since been discovered that there are several causes of variation in the ratio across the reservoir.Marine effect
The CO2 in the atmosphere transfers to the ocean by dissolving in the surface water as carbonate and bicarbonate ions; at the same time the carbonate ions in the water are returning to the air as CO2. This exchange process brings14C from the atmosphere into the surface waters of the ocean, but the 14C thus introduced takes a long time to percolate through the entire volume of the ocean. The deepest parts of the ocean mix very slowly with the surface waters, and the mixing is uneven. The main mechanism that brings deep water to the surface is upwelling, which is more common in regions closer to the equator. Upwelling is also influenced by factors such as the topography of the local ocean bottom and coastlines, the climate, and wind patterns. Overall, the mixing of deep and surface waters takes far longer than the mixing of atmospheric CO2 with the surface waters, and as a result water from some deep ocean areas has an apparent radiocarbon age of several thousand years. Upwelling mixes this "old" water with the surface water, giving the surface water an apparent age of about several hundred years (after correcting for fractionation). This effect is not uniform – the average effect is about 400 years, but there are local deviations of several hundred years for areas that are geographically close to each other. These deviations can be accounted for in calibration, and users of software such as CALIB can provide as an input the appropriate correction for the location of their samples.  The effect also applies to marine organisms such as shells, and marine mammals such as whales and seals, which have radiocarbon ages that appear to be hundreds of years old.Hemisphere effect
The northern and southern hemispheres have atmospheric circulation systems that are sufficiently independent of each other that there is a noticeable time lag in mixing between the two. The atmospheric 14C/12C ratio is lower in the southern hemisphere, with an apparent additional age of about 40 years for radiocarbon results from the south as compared to the north. This is because the greater surface area of ocean in the southern hemisphere means that there is more carbon exchanged between the ocean and the atmosphere than in the north. Since the surface ocean is depleted in 14C because of the marine effect, 14C is removed from the southern atmosphere more quickly than in the north.  The effect is strengthened by strong upwelling around Antarctica.Other effects. 
Question: What effect is not uniform?

Answer:
Upwelling.
