question:
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?
answer:
Rhizophora mangle.

Passage: As the national media descended on Beach Haven, Spring Lake, and Matawan, the Jersey Shore attacks started a shark panic. According to Capuzzo, this panic was "unrivaled in American history," "sweeping along the coasts of New York and New Jersey and spreading by telephone and wireless, letter and postcard." At first, after the Beach Haven incident, scientists and the press reluctantly blamed the death of Charles Vansant on a shark. The New York Times reported that Vansant "was badly bitten in the surf ... by a fish, presumably a shark." Still, State Fish Commissioner of Pennsylvania and former director of the Philadelphia Aquarium James M. Meehan asserted in the Philadelphia Public Ledger that the shark was preying on the dog, but bit Vansant by mistake. He specifically de-emphasized the threat sharks posed to humans:
Despite the death of Charles Vansant and the report that two sharks having been caught in that vicinity recently, I do not believe there is any reason why people should hesitate to go in swimming at the beaches for fear of man-eaters. The information in regard to the sharks is indefinite and I hardly believe that Vansant was bitten by a man-eater. Vansant was in the surf playing with a dog and it may be that a small shark had drifted in at high water, and was marooned by the tide. Being unable to move quickly and without food, he had come in to bite the dog and snapped at the man in passing.
The media's response to the second attack was more sensational. Major American newspapers such as the Boston Herald, Chicago Sun-Times, The Philadelphia Inquirer, The Washington Post and San Francisco Chronicle placed the story on the front page. The New York Times' headline read, "Shark Kills Bather Off Jersey Beach". The growing panic had cost New Jersey resort owners an estimated $250,000 ($5,800,000 in 2018) in lost tourism, and sun bathing had declined by 75 percent in some areas. A press conference was convened on July 8, 1916, at the American Museum of Natural History with scientists Frederic Augustus Lucas, John Treadwell Nichols, and Robert Cushman Murphy as panelists. To calm the growing panic, the three men stressed that a third run in with a shark was unlikely, although they were admittedly surprised that sharks bit anyone at all. Nevertheless, Nicholsthe only ichthyologist in the triowarned swimmers to stay close to shore and to take advantage of the netted bathing areas installed at public beaches after the first attack.
Question: What are the full names of the three men who were admittedly surprised that sharks bit anyone at all?
answer:
Frederic Augustus Lucas.

question:
Passage: New strains developed between the band members regarding the appointment of a financial adviser, the need for which had become evident without Epstein to manage business affairs. Lennon, Harrison and Starr favoured Allen Klein, who had managed the Rolling Stones and Sam Cooke; McCartney wanted Lee and John Eastman father and brother, respectively, of Linda Eastman, whom McCartney married on 12 March. Agreement could not be reached, so both Klein and the Eastmans were temporarily appointed: Klein as the Beatles' business manager and the Eastmans as their lawyers. Further conflict ensued, however, and financial opportunities were lost. On 8 May, Klein was named sole manager of the band, the Eastmans having previously been dismissed as the Beatles' lawyers. McCartney refused to sign the management contract with Klein, but he was out-voted by the other Beatles.Martin stated that he was surprised when McCartney asked him to produce another album, as the Get Back sessions had been "a miserable experience" and he had "thought it was the end of the road for all of us". The primary recording sessions for Abbey Road began on 2 July 1969. Lennon, who rejected Martin's proposed format of a "continuously moving piece of music", wanted his and McCartney's songs to occupy separate sides of the album. The eventual format, with individually composed songs on the first side and the second consisting largely of a medley, was McCartney's suggested compromise. On 4 July, the first solo single by a Beatle was released: Lennon's "Give Peace a Chance", credited to the Plastic Ono Band. The completion and mixing of "I Want You (She's So Heavy)" on 20 August 1969 was the last occasion on which all four Beatles were together in the same studio. Lennon announced his departure to the rest of the group on 20 September, but agreed to withhold a public announcement to avoid undermining sales of the forthcoming album.Released six days after Lennon's declaration, Abbey Road sold 4 million copies within three months and topped the UK charts for a total of seventeen weeks. Its second track, the ballad "Something", was issued as a single the only Harrison composition ever to appear as a Beatles A-side. Abbey Road received mixed reviews, although the medley met with general acclaim. Unterberger considers it "a fitting swan song for the group", containing "some of the greatest harmonies to be heard on any rock record". Musicologist and author Ian MacDonald calls the album "erratic and often hollow", despite the "semblance of unity and coherence" offered by the medley. Martin has singled it out as his personal favourite of all the band's albums; Lennon said it was "competent" but had "no life in it". Recording engineer Emerick notes that the replacement of the studio's valve mixing console with a transistorised one yielded a less punchy sound, leaving the group frustrated at the thinner tone and lack of impact and contributing to its "kinder, gentler" feel relative to their previous albums.For the still unfinished Get Back album, one last song, Harrison's "I Me Mine", was recorded on 3 January 1970. Lennon, in Denmark at the time, did not participate. In March, rejecting the work Johns had done on the project, now retitled Let It Be, Klein gave the session tapes to American producer Phil Spector, who had recently produced Lennon's solo single "Instant Karma!" In addition to remixing the material, Spector edited, spliced and overdubbed several of the recordings that had been intended as "live". McCartney was unhappy with the producer's approach and particularly dissatisfied with the lavish orchestration on "The Long and Winding Road", which involved a fourteen-voice choir and 36-piece instrumental ensemble. McCartney's demands that the alterations to the song be reverted were ignored, and he publicly announced his departure from the band on 10 April 1970, a week before the release of his first, self-titled solo album.On 8 May, the Spector-produced Let It Be was released. Its accompanying single, "The Long and Winding Road", was the Beatles' last; it was released in the United States, but not in the UK. The Let It Be documentary film followed later that month, and would win the 1970 Academy Award for Best Original Song Score. Sunday Telegraph critic Penelope Gilliatt called it "a very bad film and a touching one ... about the breaking apart of this reassuring, geometrically perfect, once apparently ageless family of siblings". Several reviewers stated that some of the performances in the film sounded better than their analogous album tracks. Describing Let It Be as the "only Beatles album to occasion negative, even hostile reviews", Unterberger calls it "on the whole underrated"; he singles out "some good moments of straight hard rock in 'I've Got a Feeling' and 'Dig a Pony'", and praises "Let It Be", "Get Back", and "the folky 'Two of Us', with John and Paul harmonising together". McCartney filed suit for the dissolution of the Beatles' contractual partnership on 31 December 1970. Legal disputes continued long after their break-up, and the dissolution was not formalised until 29 December 1974, when John Lennon signed the paperwork terminating the partnership while on vacation with his family at Walt Disney World Resort in Florida.
Question: What is the last name of the person who publicly announced his departure from the band on 10 April 1970?
answer:
McCartney.
