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.

Example Input: Passage: Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago.  Whales consist of eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the grey whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales).
Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on. They use their throat pleats to expand the mouth to take in huge gulps of water. Balaenids have heads that can make up 40% of their body mass to take in water. Toothed whales, on the other hand, have conical teeth adapted to catching fish or squid. Baleen whales have a well developed sense of "smell", whereas toothed whales have well-developed hearing − their hearing, that is adapted for both air and water, is so well developed that some can survive even if they are blind. Some species, such as sperm whales, are well adapted for diving to great depths to catch squid and other favoured prey. 
Question: What are the types of whales that use throat pleats to expand the mouth?
Example Output: Baleen.

Example Input: Passage: William Etty (1787–1849), the seventh son of a York baker and miller, had originally been an apprentice printer in Hull, but on completing his seven-year apprenticeship in 1805 moved to London to become an artist. In January 1807 he was admitted to the Royal Academy Schools as a probationer, and in July of that year became a student of renowned portrait painter Thomas Lawrence, studying under him for a year.Strongly influenced by the works of Titian and Rubens, Etty became famous for painting nude figures in biblical, literary and mythological settings. He became well-respected for his ability to capture flesh tones accurately in painting, and for his fascination with contrasts in skin tones. Many of his peers greatly admired his work, and in February 1828 he defeated John Constable by 18 votes to five to become a full Royal Academician, at the time the highest honour available to an artist.Between 1820 and 1829 Etty exhibited 15 paintings, of which 14 depicted nude figures. While some nude paintings by foreign artists existed in private collections in England, the country had no tradition of nude painting and the display and distribution of nude material to the public had been suppressed since the 1787 Proclamation for the Discouragement of Vice.Etty was the first British artist to specialise in the nude, and the prurient reaction of the lower classes to these paintings caused concern throughout the 19th century. Although his portraits of male nudes were generally well received, many critics condemned his recurrent depictions of female nudity as indecent. 
Question: What is the full name of the person who had their depictions of female nudity condemned?
Example Output: William Etty.

Example Input: 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: What is the full name of the person who has a photographic memory?
Example Output:
Dodo Doubleday.
