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?

Ex Output:
Baleen.

Passage: Melanie Daniels, a young socialite, meets criminal defense attorney Mitch Brenner in a San Francisco pet shop. Mitch wants to purchase a pair of lovebirds for his sister's eleventh birthday, but the shop has none. He recognizes Melanie from a court appearance, but she does not know him; he plays a prank by pretending to mistake her for a saleswoman. Melanie is infuriated by the prank—but finds herself romantically intrigued by Mitch.
Melanie purchases a pair of lovebirds and drives to Mitch's weekend address in Bodega Bay to deliver them. Wanting to surprise him, she rents a motorboat so she can approach the Brenner house from the bay instead of the road. She sneaks the birds inside the house and heads back across the bay. Mitch discovers the birds, spots Melanie's boat during her retreat, and drives around the bay to meet her. Melanie is attacked and injured by a seagull near shore on the town side. Mitch treats her abrasion and invites her to dinner; she hesitantly agrees.
Melanie gets to know Mitch, his domineering mother Lydia, and his younger sister Cathy. She also befriends local school teacher Annie Hayworth, Mitch's ex-lover. While spending the night at Annie's house, she and Annie are startled by a loud thud: a gull kills itself by flying into the front door. At Cathy's birthday party the next day, the guests are attacked by seagulls. The following evening, sparrows invade the Brenner home through the chimney. 
Question: What is the first name of the person who befriends a local school teacher?

Ex Output:
Melanie.

Passage: Athens' local music is based primarily in the small downtown area of the northern part of the town. The nightclub 40 Watt Club is among the most famous indie rock venues on the East Coast; the club opened on Halloween in 1978, with a band called Strictly American featuring Curtis Crowe, founder of the club and future member of the band Pylon. Other major music venues in the city include the Georgia Theater, (a converted cinema that hosted both local and touring performers. The Theater burned down in June 2009, but has been fully remodelled into a state of the art music venue reopening in early August 2011), the Caledonia Lounge, the historic Foundry Music Venue (which was originally built in 1850 as an iron foundry), and the UGA Performing Arts Center, home to the Ramsey Concert Hall and the Hugh Hodgson Concert Hall. The Morton Theater is a historic venue, a major part of the city's African American community in the early 20th century; it claims to be the only theater from that era remaining in operation.Athens is home to the summer music festival Athfest,  AlanFest, the Athens Popfest and the late spring Athens Human Rights Festival and North Georgia Folk Festival. The college radio station WUOG (90.5 FM), the low-power (100.7) FM WPPP-LP and the free weekly Flagpole are the city's most prominent modern music media. Athens has never produced a major local label like many similar indie rock towns; the most important label of the 1970s and 1980s was DB Records, based out of Atlanta, though jangle pop pioneers Kindercore Records and Wuxtry Records were also Athens-based. Athens is home to long-running indie label Happy Happy Birthday To Me Records, which has been operating consistently since 1999. 
Question: When did the long-running indie label start in the city that has a late spring music festival?

Ex Output:

1999.
