In this task, you're given a passage, further information available on a particular linked term from the statement, and an answer term. Your job is to generate a question that can use the information provided to obtain the given answer. You should use the information on both passage and link information to create the question. Note that the answer to the question should be exactly the given answer, and if the answer is none, the answer to the question shouldn't be obtainable from the passage or linked information.

Question: Passage: The original catalyst for development was the ill-fated vanity project by Lord Kensington (died 1852) which consisted of the two-mile conversion of the insanitary Counter's Creek into the Kensington Canal (1826 onwards), followed by its eventual replacement first by "Mr Punch's railway", opened in 1844 and next, by the Metropolitan District Railway in 186569, which eventually became London Underground's District Line and was joined after 1907 by the Piccadilly line. Meanwhile, the congestion apparent in London and Middlesex for burials at the start of the century was causing public concern not least on health grounds. In 1837 a decision was made to lay out a new burial ground on the edge of Earl's Court in an outlying area of Brompton. The moving spirit behind the project was the engineer, Stephen Geary. It was necessary to form a company in order to get parliamentary permission to raise capital for the proposal. Securing the land some 40 acres from local landowner, Lord Kensington and the Equitable Gas Light Company, as well as raising the money proved an extended challenge. After two years the cemetery was duly established by Act of Parliament and laid out in 1839, it opened in 1840, originally as the West of London and Westminster Cemetery. It was consecrated by Charles James Blomfield, Bishop of London in June 1840, and is now one of Britain's oldest and most distinguished garden cemeteries, served by the adjacent West Brompton station.

Answer: How many months after the Piccadily line was created did it join with the London Underground's District line?

Question: Passage: In 1986, Mitsubishi Electric researchers Yoichi Akasaka and Tadashi Nishimura laid out the basic concepts and proposed technologies for 3DICs. The following year, a Mitsubishi research team including Nishimura, Akasaka and Osaka University graduate Yasuo Inoue fabricated an image signal processor (ISP) on a 3DIC, with an array of photosensors, CMOS A-to-D converters, arithmetic logic units (ALU) and shift registers arranged in a three-layer structure. In 1989, an NEC research team led by Yoshihiro Hayashi fabricated a 3DIC with a four-layer structure using laser beam crystallisation. In 1990, a Matsushita research team including K. Yamazaki, Y. Itoh and A. Wada fabricated a parallel image signal processor on a four-layer 3DIC, with SOI (silicon-on-insulator) layers formed by laser recrystallization, and the four layers consisting of an optical sensor, level detector, memory and ALU.

Question: Passage: This led to his role as collaborator over many years with Michael Atiyah, initially via the part played by periodicity in K-theory. Bott made important contributions towards the index theorem, especially in formulating related fixed-point theorems, in particular the so-called 'Woods Hole fixed-point theorem', a combination of the RiemannRoch theorem and Lefschetz fixed-point theorem (it is named after Woods Hole, Massachusetts, the site of a conference at which collective discussion formulated it). The major AtiyahBott papers on what is now the AtiyahBott fixed-point theorem were written in the years up to 1968; they collaborated further in recovering in contemporary language Ivan Petrovsky on Petrovsky lacunas of hyperbolic partial differential equations, prompted by Lars Garding. In the 1980s, Atiyah and Bott investigated gauge theory, using the YangMills equations on a Riemann surface to obtain topological information about the moduli spaces of stable bundles on Riemann surfaces. In 1983 he spoke to the Canadian Mathematical Society in a talk he called "A topologist marvels at Physics".
