question:
Passage: In 1986, Mitsubishi Electric researchers Yoichi Akasaka and Tadashi Nishimura laid out the basic concepts and proposed technologies for 3D ICs. The following year, a Mitsubishi research team including Nishimura, Akasaka and Osaka University graduate Yasuo Inoue fabricated an image signal processor (ISP) on a 3D IC, 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 3D IC 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 3D IC, with SOI (silicon-on-insulator) layers formed by laser recrystallization, and the four layers consisting of an optical sensor, level detector, memory and ALU.
 Link Information: The company was founded in 1918 Answer: 72
answer:
A Matsushita researched teamed fabricated a parallel image signal processor how long after the company was founded?


question:
Passage: Victor (sometimes spelled Viktor) became an officer in the Royal Navy in 1848 and was promoted to Lieutenant in 1854. As a Lieutenant, he served on the first-rate HMS St Jean d'Acre in the Mediterranean under Captain Henry Keppel in 1855; commanded the gunboat HMS Traveller for a few months in 1856 after her launch until she was paid off; served again under Keppel again on the fourth-rate HMS Raleigh in the East Indies and China, until she was wrecked near Macau in 1857. He was recommended for the Victoria Cross for his service in China in 1856. He was promoted to Commander in 1857, and commanded the first-rate sloop HMS Scourge in the Mediterranean. Promoted to Captain in 1859, he took command of the 21-gun corvette HMS Racoon from commissioning in 1863 until 1866, during which time Queen Victoria's second son, Alfred, Duke of Edinburgh (1844–1900) served on board as a lieutenant.
 Link Information: Henry Keppel (14 June 1809 – 17 January 1904 Answer: 46
answer:
How old was Henry Keppel when Prince Victor of Hohenlohe-Langenburg served under him?


question:
Passage: Alabama was central to the Civil War, with the secession convention at Montgomery, birthplace of the Confederacy, inviting other states to form a Southern Republic, during January–March 1861, and develop constitutions to legally run their own affairs. The 1861 Alabama Constitution granted citizenship to current U.S. residents, but prohibited import duties (tariffs) on foreign goods, limited a standing military, and as a final issue, opposed emancipation by any nation, but urged protection of African slaves, with trial by jury, and reserved the power to regulate or prohibit the African slave trade. The secession convention invited all slaveholding states to secede, but only 7 Cotton States of the Lower South formed the Confederacy with Alabama, while the majority of slave states were in the Union and voted to make U.S. slavery permanent by passing the Corwin Amendment, signed by President Buchanan and backed by President Lincoln on March 4, 1861.
 Link Information: Beginning February 4, 1861, representatives from Alabama, Georgia, Florida, Louisiana, Mississippi, and South Carolina met in Montgomery, host of the Southern Convention, to form the Confederate States of America. Answer: Beginning February 4, 1861
answer:

What dates did the secession convention occur in Alabama?
