Input: Read this: An 1855 paper on the "introduction" of species, written by Alfred Russel Wallace, claimed that patterns in the geographical distribution of living and fossil species could be explained if every new species always came into existence near an already existing, closely related species. Charles Lyell recognised the implications of Wallace's paper and its possible connection to Darwin's work, although Darwin did not, and in a letter written on 1–2 May 1856 Lyell urged Darwin to publish his theory to establish priority. Darwin was torn between the desire to set out a full and convincing account and the pressure to quickly produce a short paper. He met Lyell, and in correspondence with Joseph Dalton Hooker affirmed that he did not want to expose his ideas to review by an editor as would have been required to publish in an academic journal. He began a "sketch" account on 14 May 1856, and by July had decided to produce a full technical treatise on species. His theory including the principle of divergence was complete by 5 September 1857 when he sent Asa Gray a brief but detailed abstract of his ideas.
Question: Which scientist recognized the possible validity and implications of Wallace's paper?

Output: Charles Lyell


QUES: Due to the Budget sequestration in 2013, the USAF was forced to ground many of its squadrons. The Commander of Air Combat Command, General Mike Hostage indicated that the USAF must reduce its F-15 and F-16 fleets and eliminate platforms like the A-10 in order to focus on a fifth-generation jet fighter future. In response to squadron groundings and flight time reductions, many Air Force pilots have opted to resign from active duty and enter the Air Force Reserve and Air National Guard while pursuing careers in the commercial airlines where they can find flight hours on more modern aircraft.

Why was the USAF forced to ground some of its squadrons in 2013?
What is the answer?
ANS: Budget sequestration


QUES: Madonna experimented with more folk and acoustic music in Music (2000) and American Life (2003). A change was noted in the content of the songs in Music, with most of them being simple love songs, but with an underlying tone of melancholy. According to Q magazine, American Life was characterized by "a thumping techno rhythm, liquid keyboard lines, an acoustic chorus and a bizarre Madonna rap." The "conventional rock songs" of the album were suffused with dramatic lyrics about patriotism and composition, including the appearance of a gospel choir in the song "Nothing Fails". Madonna returned to pure dance songs with Confessions on a Dance Floor, infusing club beats and retro music with the lyrics about paradoxical metaphors and reference to her earlier works. Madonna moved to urban direction with Hard Candy (2008), mixing R&B and hip hop music with dance tunes. MDNA (2012) largely focused in electronic dance music, which she has embraced since Ray of Light.
Most of the songs in Music are what type of songs?

ANS: simple love songs,


In the UK, the London, Brighton and South Coast Railway pioneered overhead electrification of its suburban lines in London, London Bridge to Victoria being opened to traffic on 1 December 1909. Victoria to Crystal Palace via Balham and West Norwood opened in May 1911. Peckham Rye to West Norwood opened in June 1912. Further extensions were not made owing to the First World War. Two lines opened in 1925 under the Southern Railway serving Coulsdon North and Sutton railway station. The lines were electrified at 6.7 kV 25 Hz. It was announced in 1926 that all lines were to be converted to DC third rail and the last overhead electric service ran in September 1929.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the cause of lines not being extended?
Ah, so.. the First World War


Question: On July 25, 2015, the 18th and 19th satellites were successfully launched from the Xichang Satellite Launch Center, marking the first time for China to launch two satellites at once on top of a Long March 3B/Expedition-1 carrier rocket. The Expedition-1 is an independent upper stage capable of delivering one or more spacecraft into different orbits.
Try to answer this question if possible: This marked the third time China launched how many satellites at once? 
Answer: unanswerable


Context and question: At the age of 21 he settled in Paris. Thereafter, during the last 18 years of his life, he gave only some 30 public performances, preferring the more intimate atmosphere of the salon. He supported himself by selling his compositions and teaching piano, for which he was in high demand. Chopin formed a friendship with Franz Liszt and was admired by many of his musical contemporaries, including Robert Schumann. In 1835 he obtained French citizenship. After a failed engagement to Maria Wodzińska, from 1837 to 1847 he maintained an often troubled relationship with the French writer George Sand. A brief and unhappy visit to Majorca with Sand in 1838–39 was one of his most productive periods of composition. In his last years, he was financially supported by his admirer Jane Stirling, who also arranged for him to visit Scotland in 1848. Through most of his life, Chopin suffered from poor health. He died in Paris in 1849, probably of tuberculosis.
In the last years of his life who was the person that supported him financially?
Answer:
Jane Stirling
