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: Three species of mangrove trees exist in the region: red (Rhizophora mangle), black (Avicennia germinans), and white (Laguncularia racemosa), although all are from different families. All have the same characteristics: they are tolerant of salt, brackish, and fresh water; they grow in oxygen-poor soil; and they can survive drastic water-level changes. Black and white mangroves excrete salt from under their leaves, and red mangroves filter the salinity of sea water. All species are integral to coastline protection during severe storms. Red mangroves, for example, have far-reaching roots that trap sediments. The trees not only stabilize coastlines, but add land as more sand and decaying vegetation is trapped in the root systems. All three mangroves also absorb the energy of waves and storm surges.
The estuaries act as fisheries for fry and nurseries for crustaceans. Shrimp, oysters, crabs, whelks, cockles, and snails thrive in these waters, as do primordial horseshoe crabs (Limulus polyphemus). The region supports a $59 million-a-year Tortugas pink shrimp (Farfantepenaeus duorarum) industry, and a $22 million-a-year stone crab (Menippe mercenaria) industry.  Between 80 and 90 percent of species that are harvested commercially in Florida are born or spend time in the shallow waters near the Everglades. Oysters and mangroves work in tandem to build up the coastline. The sand around the coastline has minute white particles of quartz and fine shells. When currents are right, oysters grow in colonies or beds, and deposit their shells, reinforcing the bed. Mangrove seeds, called propagules, are full embryos and float in water until they reach a favorable location and take root, often on oyster beds. They shed skin and litter, ensuring other trees will not compete for space and nutrients.Mangroves also serve as excellent rookeries for birds. Wading birds, such as roseate spoonbills (Platalea ajaja), egrets, and tricolored herons (Egretta tricolor) use the mangroves as a nursery, due to the proximity of food sources and the protection offered from most prey. Thousands of birds can nest in the mangroves at once, making a noisy and messy colony, but their droppings fertilize the mangrove trees. Shorebirds like rails, terns and gulls; diving birds such as pelicans and grebes; and birds of prey such as ospreys, hawks and vultures are among the more than 100 species of birds that use Everglades mangrove trees to raise their young. 
Question: What are the full scientific names of the three species of mangrove trees that exist in the Everglades?

A: Rhizophora mangle.

Q: Passage: Since King George VI's death, Queen Elizabeth II's custom has been to spend the anniversary of that and of her own accession privately with her family at Sandringham House, and, more recently, to use it as her official base from Christmas until February. In celebrating Christmas at Sandringham, the Queen follows the tradition of her last three predecessors, whereas her great-great-grandmother, Queen Victoria, held her celebrations at Windsor Castle. The taxation arrangements of the monarch meant that no inheritance tax was paid on the Sandringham or Balmoral estates when they passed to the Queen, at a time when it was having a deleterious effect on other country estates. On her accession, the Queen asked her husband, the Duke of Edinburgh, to take on the responsibility for the management of the estate. The Duke has worked to move towards self-sufficiency, generating additional income streams, taking more of the land in hand, and amalgamating many of the smaller tenant farms.In January 1957 the Queen received the resignation of the Prime Minister Anthony Eden at the house. Eden's wife, Clarissa, recorded the event in her diary, "8 January – Anthony has to go through a Cabinet and listening to Harold prosing for half an hour. Then by train to Sandringham. Many photographers. We arrive into the hall where everyone is looking at the television." At the end of that year, the Queen made her first televised Christmas broadcast from Sandringham. In the 1960s, plans were initiated to demolish the house and replace it with a modern residence by David Roberts, an architect who worked mainly at the University of Cambridge. The plans were not taken forward, but modernisation of the interior of the house and the removal of a range of ancillary buildings were carried out by Hugh Casson, who also decorated the Royal Yacht, Britannia. In 1977, for her silver jubilee, the Queen opened the house to the public.Sandringham continues to operate as a sporting estate. The pheasants and partridge are no longer reared for this purpose, and Sandringham is now one of the few wild shoots in England. Along with her equestrian interest in the Sandringham Stud, where she has bred several winning horses, the Queen has developed a successful gun dog breeding programme at Sandringham. Following the tradition of a kennels at Sandringham established by her great grandfather, when Queen Alexandra kept over 100 dogs on the estate, the Queen prefers black labrador retrievers, over the yellow type favoured by her father, and the terriers bred by her earlier predecessors. Since his retirement from official duties in August 2017, the Duke of Edinburgh has spent increasing amounts of time at Wood Farm, a cottage on the Sandringham Estate used by the Duke and the Queen when not hosting guests at the main house. Sandringham is one of the two homes owned by the Queen in her private capacity, rather than as head of state, the other being Balmoral Castle. 
Question: What is the full name of the person whose last three predecessors set the tradition for celebrating Christmas at Sandringham that she follows?

A: Queen Elizabeth II.

Q: Passage: Michael is looking for a woman who likes to play games, but when he finds Suzanne, he discovers to his cost that she may be more than he bargained for, especially since common sense does not show itself to be one of his assets or advantages. Once Michael meets Suzanne, they strike up a relationship which proves to be intense. Their first date takes them, first, to a restaurant, then into an alley where they fool around for a bit. They go back to his place to fool around some more. She then leaves. The next day, both attend a business meeting, during whose course Suzanne plays footsie with Michael. They return to his residence to fool around in his bathtub, then move onto his bed to try to fool around some more. But Suzanne flees and boards a taxi. This causes Michael, still naked under a bathrobe, to run after the cab taking Suzanne away. These actions reveal Suzanne to be very selfish, and Michael to be rather stupid in the practical sense. Arrested for indecent exposure, Michael places two telephone calls seeking release on bail. The first, to Suzanne, is without success. The second, to Nick, one of his friends, yields results. Suzanne then lures Michael to a motel bed and leaves him cuffed there to the bed naked while she leaves to go back to work to attend a meeting. She returns to him and they have sex on the motel bed. 
Question: Who has a friend named Nick?

A:
Michael.
