question:
Passage: Conquistadors often wore steel armour that included chainmail and helmets. The Spanish were sufficiently impressed by the quilted cotton armour of their Maya enemies that they adopted it in preference to their own steel armour. Maya weaponry was not sufficiently powerful to justify the discomfort of wearing European armour. Quilted cotton armour, although still uncomfortably hot, was flexible and weighed much less. The Maya armour was adapted by the Spanish, who used knee-length quilted cotton tunics and Spanish-style caps. Horsemen wore long quilted cotton leg protectors; their horses were also protected with padded cotton armour. After the final push to the Petén lakes in early 1697, the Spanish recorded that they left with their garrison over 50 Dutch- and French-made muskets, three 1-pound (0.45 kg) calibre light cannons (piezas) cast from iron and mounted on carriages, four iron and two bronze pedreros (2-chambered stone-launchers) and six of at least eight bronze light cannons (known as esmiriles). 
Question: Who had four iron and two bronze pedreros?
answer:
the Spanish.


question:
Passage: The Mozart family grand tour was a journey through western Europe, undertaken by Leopold Mozart, his wife Anna Maria, and their musically gifted children Maria Anna (Nannerl) and Wolfgang Amadeus from 1763 to 1766. At the start of the tour the children were aged eleven and seven respectively. Their extraordinary skills had been demonstrated during a visit to Vienna in 1762, when they had played before the Empress Maria Theresa at the Imperial Court. Sensing the social and pecuniary opportunities that might accrue from a prolonged trip embracing the capitals and main cultural centres of Europe, Leopold obtained an extended leave of absence from his post as deputy Kapellmeister to the Prince-Archbishopric of Salzburg. Throughout the subsequent tour, the children's Wunderkind status was confirmed as their precocious performances consistently amazed and gratified their audiences.
The first stage of the tour's itinerary took the family, via Munich and Frankfurt, to Brussels and then on to Paris where they stayed for five months. They then departed for London, where during a stay of more than a year Wolfgang made the acquaintance of some of the leading musicians of the day, heard much music, and composed his first symphonies. The family then moved on to the Netherlands, where the schedule of performances was interrupted by the illnesses of both children, although Wolfgang continued to compose prolifically. The homeward phase incorporated a second stop in Paris and a trip through Switzerland, before the family's return to Salzburg in November 1766.
The material rewards of the tour, though reportedly substantial, did not transform the family's lifestyle, and Leopold continued in the Prince-Archbishop's service. However, the journey enabled the children to experience to the full the cosmopolitan musical world, and gave them an outstanding education. In Wolfgang's case this would continue through further journeys in the following six years, prior to his appointment by the Prince-Archbishop as a court musician. 
Question: What location did the touring musician family return to at the end of the tour?
answer:
Salzburg.

Passage: During the First World War, a British officer - David Compton - on leave from the trenches in Paris falls in love with and has a liaison of three days with a French performing artist: Deloryse/Lola. He proposes to her and tells her to get ready for the wedding in an hour. He rushes to search for the English church. On the way he meets his superior, who tells him that he has to report immediately, they have to leave Paris. He doesn't even have the time to see his fiancé again.
After returning to fight on the front, he suffers from shellshock and forgets everything that happened in the last four years. After recovering he goes back to his wealthy life of rich industrialist, marries a British Socialite, with whom he runs entirely separate lives. She is the one to invite Deloryse to London to dance on one of her charity events. While dancing and singing on the stage she sees him in a loge. During her second number, where she sings the same song of when he met her in Paris, he finally has a flash back of the song and the singer. After the performance he sends her a notice that he wants to see her. She's very excited, but when Doctor Gavron comes to see her, he measures her pulse and tells her, that she has to give up the stage, as the strain might kill her, even if she dances once more. Then David comes. He meets her and his son Davey. But  he is now married to a British Socialite: Vesta Compton, who never wanted children, to the big regret of her husband. 
Question: What is the full name of the person who invites Deloryse to London?
