Question:
Jose Rizal was born in 1861 to Francisco Mercado and Teodora Alonso in the town of Calamba in Laguna province. He had nine sisters and one brother. His parents were leaseholders of a hacienda and an accompanying rice farm by the Dominicans. Both their families had adopted the additional surnames of Rizal and Realonda in 1849, after Governor General Narciso Claveria
Jose Rizal's life is one of the most documented of 19th century Filipinos due to the vast and extensive records written by and about him. Almost everything in his short life is recorded somewhere, being himself a regular diarist and prolific letter writer, much of the material having survived. His biographers, however, have faced difficulty in translating his writings because of Rizal's habit of switching from one language to another.  They drew largely from his travel diaries with their insights of a young Asian encountering the West for the first time. They included his later trips, home and back again to Europe through Japan and the United States, and, finally, through his self-imposed exile in Hong Kong.  Shortly after he graduated from the Ateneo Municipal de Manila (now Ateneo de Manila University), Rizal (who was then 16 years old) and a friend, Mariano Katigbak, came to visit Rizal's maternal grandmother in Tondo, Manila. Mariano brought along his sister, Segunda Katigbak, a 14-year-old Batanguena from Lipa, Batangas. It was the first time they met and Rizal described Segunda as "rather short, with eyes that were eloquent and ardent at times and languid at others, rosy-cheeked, with an enchanting and provocative smile that revealed very beautiful teeth, and the air of a sylph; her entire self diffused a mysterious charm." His grandmother's guests were mostly college students and they knew that Rizal had skills in painting. They suggested that Rizal should make a portrait of Segunda. He complied reluctantly and made a pencil sketch of her. Unfortunately for him, Katigbak was engaged to Manuel Luz.  From December 1891 to June 1892, Rizal lived with his family in Number 2 of Rednaxela Terrace, Mid-levels, Hong Kong Island. Rizal used 5 D'Aguilar Street, Central district, Hong Kong Island, as his ophthalmologist clinic from 2 pm to 6 pm. This period of his life included his recorded affections of which nine were identified. They were Gertrude Beckett of Chalcot Crescent, London, wealthy and high-minded Nelly Boustead of the English and Iberian merchant family, last descendant of a noble Japanese family Seiko Usui (affectionately called O-Sei-san), his earlier friendship with Segunda Katigbak, Leonor Valenzuela, and eight-year romantic relationship with a distant cousin, Leonor Rivera (popularly thought to be the inspiration for the character of Maria Clara in Noli me tangere).

Answer the question at the end by quoting:

Curved Air are a pioneering English progressive rock group formed in 1970 by musicians from mixed artistic backgrounds, including classical, folk, and electronic sound. The resulting sound of the band was a mixture of progressive rock, folk rock, and fusion with classical elements. Along with High Tide and East of Eden, Curved Air were one of the first rock bands after It's a Beautiful Day and the United States of America to feature a violin. Curved Air released eight studio albums, the first three of which broke the UK Top 20, and had a hit single with "Back Street Luv" (1971) which reached number 4 in the UK Singles Chart.
Having retained a good working relationship, Sonja Kristina and Mike Wedgwood formed a new band with Kirby Gregory (electric guitar), Eddie Jobson (keyboards, violin), and Jim Russell (drums). Jobson had come from a band called Fat Grapple, who had been one of Curved Air's support acts on tour. This new band played a much more conventional brand of rock than the former Curved Air, with almost none of the classical influences of that group. However, on the suggestion of manager Clifford Davis, they continued using the name Curved Air so as to give them a commercial leg up.  Kristina later commented:  What I wanted to do with the band at the time was get more of a rock edge to it, and Kirby's guitar playing really excited me - he was just really wild. And Jim was the same way, a very solid rock drummer. Mike and I really wanted to continue, and it was our manager Clifford Davis who said we would do a better business continuing to call the band Curved Air. So we kept the name and followed along the same pattern as before, as a writer's band. Everybody in the new band contributed material except for Jim Russell, who really wasn't a writer. Before it had mainly been Darryl and Francis, but I had managed to get some of my compositions in.  The use of the Curved Air name was not enough, however. Whereas all three of the original Curved Air's albums had broken the UK top 20, the new band's sole album, Air Cut, failed to even chart. Due to artistic differences with Jobson, Kirby Gregory and Jim Russell both left the group to form Stretch. Warner Brothers realized that the current Curved Air was in essence not the same band they had signed, and so the remaining trio recorded a demo tape for the label. The demos failed to convince Warner Brothers, and they discontinued the contract. (These demos were later issued as part of the Lovechild record.) With no contract and only half a lineup, in summer 1973 Curved Air broke up. Jobson replaced Eno in Roxy Music, while Wedgwood joined Caravan.
