Input: Consider Input: Passage: The gut is generally an almost straight tube supported by the mesenteries (vertical partitions within segments), and ends with the anus on the underside of the pygidium. However, in members of the tube-dwelling family Siboglinidae the gut is blocked by a swollen lining that houses symbiotic bacteria, which can make up 15% of the worms' total weight. The bacteria convert inorganic matter – such as hydrogen sulfide and carbon dioxide from hydrothermal vents, or methane from seeps – to organic matter that feeds themselves and their hosts, while the worms extend their palps into the gas flows to absorb the gases needed by the bacteria. Question: How much of a Siboglinidae's weight is symbiotic bacteria?

Output: 15%


Input: Consider Input: Passage: In the spring of 1834, Chopin attended the Lower Rhenish Music Festival in Aix-la-Chapelle with Hiller, and it was there that Chopin met Felix Mendelssohn. After the festival, the three visited Düsseldorf, where Mendelssohn had been appointed musical director. They spent what Mendelssohn described as "a very agreeable day", playing and discussing music at his piano, and met Friedrich Wilhelm Schadow, director of the Academy of Art, and some of his eminent pupils such as Lessing, Bendemann, Hildebrandt and Sohn. In 1835 Chopin went to Carlsbad, where he spent time with his parents; it was the last time he would see them. On his way back to Paris, he met old friends from Warsaw, the Wodzińskis. He had made the acquaintance of their daughter Maria in Poland five years earlier, when she was eleven. This meeting prompted him to stay for two weeks in Dresden, when he had previously intended to return to Paris via Leipzig. The sixteen-year-old girl's portrait of the composer is considered, along with Delacroix's, as among Chopin's best likenesses. In October he finally reached Leipzig, where he met Schumann, Clara Wieck and Felix Mendelssohn, who organised for him a performance of his own oratorio St. Paul, and who considered him "a perfect musician". In July 1836 Chopin travelled to Marienbad and Dresden to be with the Wodziński family, and in September he proposed to Maria, whose mother Countess Wodzińska approved in principle. Chopin went on to Leipzig, where he presented Schumann with his G minor Ballade. At the end of 1836 he sent Maria an album in which his sister Ludwika had inscribed seven of his songs, and his 1835 Nocturne in C-sharp minor, Op. 27, No. 1. The anodyne thanks he received from Maria proved to be the last letter he was to have from her. Question: What was the first name of the girl Chopin proposed to?

Output: Maria


Input: Consider Input: Passage: Oda Nobunaga made innovations in the fields of organization and war tactics, heavily used arquebuses, developed commerce and industry and treasured innovation. Consecutive victories enabled him to realize the termination of the Ashikaga Bakufu and the disarmament of the military powers of the Buddhist monks, which had inflamed futile struggles among the populace for centuries. Attacking from the "sanctuary" of Buddhist temples, they were constant headaches to any warlord and even the Emperor who tried to control their actions. He died in 1582 when one of his generals, Akechi Mitsuhide, turned upon him with his army. Question: Who used arquebuses a lot?


Output: Oda Nobunaga
