question:
Passage: In 1938 Egypt, a team of archaeologists discover the tomb of pharaoh Ahkmenrah, including a young Cecil Fredericks, finding the magical Tablet of Ahkmenrah. The locals warn the group that removing the tablet will end its magic. In present-day New York City, Larry Daley remains the night guard of the American Museum of Natural History. He, Theodore Roosevelt, Sacagawea, Attila the Hun, Jedediah, Octavius, Rexy the Tyrannosaurus rex skeleton and Dexter the capuchin monkey help re-open the Hayden Planetarium. A new wax Neanderthal resembling Larry named Laaa is introduced, identifying Larry as his father. Ahkmenrah shows Larry that the tablet is corroding, which later causes the exhibits to act erratically, causing mayhem at the planetarium's reopening. Afterwards, Larry catches his son Nick, who plans on taking a gap year to sort out his life, throwing a house party.
Larry reunites with Cecil, now in retirement, who realizes the end of the tablet's magic will cause the exhibits to become lifeless. Cecil explains that Ahkmenrah's parents, Merenkahre and Shepseheret, may be able to restore the tablet's power but that they are located in the British Museum. Larry convinces the museum's curator, Dr. McPhee, to let him ship Ahkmenrah to London to restore the tablet, convinced that McPhee knows its secrets. Larry and Nick travel to the British Museum, bypassing the night guard Tilly. To Larry's surprise, Roosevelt, Sacagawea, Attila, Jed, Octavius, Dexter and Laaa have come as well, and Laaa is left to stand guard while the others search the museum, the tablet bringing its own exhibits to life. 
Question: What is the last name of the person who is helped by the museum exhibits to re-open the planetarium?
answer:
Daley.

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?
answer:
Baleen.


question:
Passage: Altrincham became a Free Borough, a self-governing township, when it was granted a charter in June 1290 by the Lord of the Manor, Hamon de Massey V. The charter allowed for the creation of a merchants' guild, run by the town's burgesses to tax people passing through the borough. Burgesses were free men who lived in the town. The borough was ruled by a Court Leet and elected a mayor since at least 1452. Amongst the court's responsibilities were keeping the public peace and regulating the markets and fairs.The borough was not one of those reformed by the Municipal Corporations Act of 1835, and continued to exist under the control of the Lord of the Manor and the Court Leet until its final abolition in 1886. The Public Health Act of 1848 led to the creation of Altrincham's Local Board of Health in 1851 to address the unsanitary conditions created by the town's growing population – the first such board in Trafford.The local board was reconstituted as an urban district council in the administrative county of Cheshire under the Local Government Act 1894. Altrincham Urban District was expanded in 1920 when parts of Carrington and Dunham Massey Civil Parishes were added. A further expansion took place in 1936; Timperley Civil Parish was abolished and most of its area incorporated into Altrincham UD. At the same time, there was a minor exchange of areas with Hale Urban District; a minor addition from Bowdon Urban District; and a further substantial portion of Dunham Massey Civil Parish was added. In 1937 the urban district was granted a charter of incorporation and became a municipal borough. The new borough was granted armorial bearings which featured heraldic references to the Masseys and Earls of Stamford. With the passage of the Local Government Act 1972, the administrative counties and municipal boroughs were abolished and Altrincham became part of the Metropolitan Borough of Trafford in Greater Manchester on 1 April 1974.Trafford Council is responsible for the administration of local services, such as education, social services, town planning, waste collection and council housing. The area is divided into seven electoral wards: Altrincham, Bowdon, Broadheath, Hale Barns, Hale Central, Timperley, and Village. These wards have 21 out of the 63 seats on the Trafford Council; as of the 2014 local elections fifteen of these seats were held by the Conservative Party, three by the Labour Party, and three by the Liberal Democrats. Altrincham was in the eponymous parliamentary constituency which was created in 1885. This lasted until 1945 when it was replaced by Altrincham and Sale. In 1997, this in turn became part of the newly created constituency of Altrincham and Sale West. Since its formation, Altrincham and Sale West has been represented in the House of Commons by the Conservative MP, Graham Brady. This is one of only four Conservative seats in Greater Manchester. 
Question: What are the exact names of the seven electoral wards wards that have 21 out of the 63 seats on the Trafford Council?
answer:

Altrincham.
