TASK DEFINITION: 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.
PROBLEM: 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?

SOLUTION: Rhizophora mangle.

PROBLEM: Passage: Dodo Doubleday has been inexplicably reduced from first sergeant to staff sergeant and has resumed being orderly to his regimental commander Colonel Barkley.  Sergeant Ames is still a buck sergeant who hates Dodo because he advanced to outrank Ames within Dodo's first 24 hours in the army.  Dodo's former comrade in arms Charlie Cobb is also a buck sergeant.  As both Cobb and Ames are the best marksman in the regiment but constantly boast of their prowess, Colonel Barkley seeks to find an expert who can outshoot them.
Though possessing a photographic memory that enabled him to advance from private to senior non-commissioned officer in less than 24 hours, Dodo has one weakness: though his book knowledge enables him to give lectures on weapons disassembly and ballistics, he is gun shy and an incompetent marksman. After nearly shooting several of his fellow soldiers on the pistol range, with the actual target being the safest place to hide, Dodo is ordered to go into the woods to practice.  There his missed shots impress the picnicking colonel and his daughter Betty when Dodo accidentally shoots a hawk through the eye whilst in flight and after the colonel catches a fish who breaks the line and is in the process of rolling back into the water, an accidental discharge from Dodo's pistol shoots the fish through his eye.  Eager to deflate the boasting Ames and Cobb, the colonel bets a month's pay that Dodo can outshoot Ames and Cobb.
Ames and Cobb's hatred of Dodo increases when in the interests of promoting democracy in the United States Army, Betty invites Dodo to dinner at the colonel's quarters, but Ames and Cobb believe they have been invited as well. 
Question: Who is picnicking with the man that wants to find someone who can outshoot the buck sergeants?

SOLUTION: Betty.

PROBLEM: Passage: John Winston Ono Lennon  (9 October 1940 – 8 December 1980) was an English singer, songwriter and peace activist who co-founded the Beatles, the most commercially successful band in the history of popular music. He and fellow member Paul McCartney formed a much-celebrated songwriting partnership. Along with George Harrison and Ringo Starr, the group achieved worldwide fame during the 1960s. In 1969, Lennon started the Plastic Ono Band with his second wife, Yoko Ono, and he continued to pursue a solo career following the Beatles' break-up in April 1970.
Born  John Winston Lennon in Liverpool, he became involved in the skiffle craze as a teenager. In 1957, he formed his first band, the Quarrymen, which evolved into the Beatles in 1960. Further to his Plastic Ono Band singles such as "Give Peace a Chance" and "Instant Karma!", Lennon subsequently produced albums that included John Lennon/Plastic Ono Band and Imagine, and songs such as  "Working Class Hero", "Imagine" and "Happy Xmas (War Is Over)". After moving to New York City in 1971, he never returned to England again. In 1975, he disengaged himself from the music business to raise his infant son Sean, but re-emerged with Ono in 1980 with the album Double Fantasy. He was shot and killed in the archway of his Manhattan apartment building three weeks after the album's release.
Lennon revealed a rebellious nature and acerbic wit in his music, writing, drawings, on film and in interviews. He was controversial through his political and peace activism. From 1971 onwards, his criticism of the Vietnam War resulted in a three-year attempt by the Nixon administration to deport him. Some of his songs were adopted as anthems by the anti-war movement and the larger counterculture.
By 2012, Lennon's solo album sales in the United States had exceeded 14 million units. He had 25 number-one singles on the US Billboard Hot 100 chart as a writer, co-writer or performer. In 2002, Lennon was voted eighth in a BBC poll of the 100 Greatest Britons and in 2008, Rolling Stone ranked him the fifth-greatest singer of all time.  In 1987, he was posthumously inducted into the Songwriters Hall of Fame. Lennon was twice posthumously inducted into the Rock and Roll Hall of Fame: first in 1988 as a member of the Beatles and again in 1994 as a solo artist. 
Question: What is the first name of the person whose solo album sales in the United States had exceeded 14 million units?

SOLUTION:
John.
