Passage: In February 1935, at Bridge's instigation, Britten was invited to a job interview by the BBC's director of music Adrian Boult and his assistant Edward Clark. Britten was not enthusiastic about the prospect of working full-time in the BBC music department and was relieved when what came out of the interview was an invitation to write the score for a documentary film, The King's Stamp, directed by Alberto Cavalcanti for the GPO Film Unit.
Britten became a member of the film unit's small group of regular contributors, another of whom was W. H. Auden. Together they worked on the documentary films Coal Face and Night Mail in 1935. They also collaborated on the song cycle Our Hunting Fathers (1936), radical both in politics and musical treatment, and subsequently other works including Cabaret Songs, On This Island, Paul Bunyan and Hymn to St. Cecilia. Auden was a considerable influence on Britten, encouraging him to widen his aesthetic, intellectual and political horizons, and also to come to terms with his homosexuality. Auden was, as David Matthews puts it, "cheerfully and guiltlessly promiscuous"; Britten, puritanical and conventional by nature, was sexually repressed.In the three years from 1935 to 1937 Britten wrote nearly 40 scores for the theatre, cinema and radio. Among the film music of the late 1930s Matthews singles out Night Mail and Love from a Stranger (1937); from the theatre music he selects for mention  The Ascent of F6 (1936), On the Frontier (1938) and Johnson Over Jordan (1939); and of the music for radio, King Arthur (1937) and The Sword in the Stone (1939).In 1937 there were two events of huge importance in Britten's life: his mother died, and he met the tenor Peter Pears. Although Britten was extraordinarily devoted to his mother and was devastated at her death, it also seems to have been something of a liberation for him. Only after that did he begin to engage in emotional relationships with people his own age or younger. Later in the year he got to know Pears while they were both helping to clear out the country cottage of a mutual friend who had died in an air crash. Pears quickly became Britten's musical inspiration and close (though for the moment platonic) friend. Britten's first work for him was composed within weeks of their meeting, a setting of Emily Brontë's poem, "A thousand gleaming fires", for tenor and strings.During 1937 Britten composed a Pacifist March to words by Ronald Duncan for the Peace Pledge Union, of which, as a pacifist, he had become an active member; the work was not a success and was soon withdrawn. The best known of his compositions from this period is probably Variations on a Theme of Frank Bridge for string orchestra, described by Matthews as the first of Britten's works to become a popular classic. It was a success in North America, with performances in Toronto, New York, Boston, Chicago and San Francisco, under conductors including John Barbirolli and Serge Koussevitzky. 
Question: What was the name of the company Britten became a member of?
answer:
GPO Film Unit.


question:
Passage: Writing after the fall of Nojpetén, friar Cano described the ultimate fate of Díaz de Velasco and his companions; he claimed to have received the information from interviews with the soldiers from Yucatán who had stormed the Itza capital and from Chʼol witnesses, although there were no Chʼol at Nojpetén. Díaz's party arrived at the lakeshore and were told by local Itza that Franciscan friars were at Nojpetén. They were wary at first and asked for proof, upon which an Itza messenger brought them a rosary as a token. Looking across the lake they saw men dressed as friars calling to them to come across, these were Itza dressed in the habits of the two Franciscans who had recently been killed at the island. Díaz and his companions then boarded the Itza canoes, leaving thirty Maya porters with their mules and supplies.Once on the lake the Itza overturned some of the canoes and killed some of Díaz's men; others were wounded and dragged ashore to be killed. Díaz, the Dominicans and two other men were in a large canoe that was not overturned and were taken to Nojpetén where a fierce struggle ensued as Díaz attempted to defend himself with his sword, killing several Itzas. The two other men were immediately killed while the friars were beaten and tied to X-shaped crosses before having their hearts cut out. Across the lake, the Itza attacked the porters guarding the expedition supplies and killed all of them. The Itza killed a total of 87 expedition members, including 50 soldiers, two Dominicans and about 35 Maya helpers. The remains of the small group that were killed on Nojpetén were later retrieved by the Spanish after the fall of the city and were taken back to Santiago de los Caballeros de Guatemala for burial. 
Question: What is the first name of the leader of the party that were wary at first and asked for proof?
answer:
Díaz.

Passage: The SSSI is designated as a Special Protection Area for birds for its variety of coastal habitats. The large breeding colonies of Sandwich terns and little terns, especially those at Blakeney Point and Scolt Head Island, are of "European importance" as defined in the Birds Directive, and the coast as a whole meets Natural England's criteria for nationally important populations of common terns, pied avocets and reedbed specialists like western marsh harriers, Eurasian bitterns and bearded reedlings. Other birds nesting in the wetlands include the northern lapwing, common redshank, and sedge, reed and Cetti's warblers. Ringed plovers and Eurasian oystercatchers lay their eggs on bare sand in the dunes. Little egrets, Eurasian spoonbills, ruffs and black-tailed godwits are present for much of the year, and the egret and spoonbill have both started nesting within the SSSI.In spring and early summer, migrant birds including the little gull, black tern, Temminck's stint and garganey may pass through on their way to breed elsewhere. In the autumn, birds arrive from the north; some, such as whimbrels, curlew sandpipers and little stints, just pausing for a few days to refuel before continuing south, others staying for the winter. Offshore, great and Arctic skuas, northern gannets and black-legged kittiwakes may pass close by in favourable winds. Large numbers of ducks winter along the coast, including many Eurasian wigeons, Eurasian teals, mallards and gadwalls, goldeneyes and northern pintails. Red-throated divers are usually on the sea, and brent geese feed on sea lettuce and other green algae. Barn owls and sometimes hen harriers quarter the marshes in winter, and snow bunting flocks can be found on the beaches. Thousands of geese, mainly pink-footed, roost at Holkham.The SSSI's north-facing east coast location can be favourable for huge numbers of migrating birds when the weather conditions are right. These may include vagrant rarities. A black-winged stilt, which acquired the nickname "Sammy", arrived at Titchwell in 1993 and became a permanent resident up to its disappearance in 2005. Other major rarities included a western sandpiper at Cley in 2012, a rufous-tailed robin at Warham Greens in 2011, and a black-winged pratincole at Titchwell in 2009. 
Question: What is the type of rare bird that arrived to Titchwell in 1993?
answer:

black-winged stilt.
