Problem: Computer:

In 1941, Zuse followed his earlier machine up with the Z3, the world's first working electromechanical programmable, fully automatic digital computer. The Z3 was built with 2000 relays, implementing a 22 bit word length that operated at a clock frequency of about 5–10 Hz. Program code was supplied on punched film while data could be stored in 64 words of memory or supplied from the keyboard. It was quite similar to modern machines in some respects, pioneering numerous advances such as floating point numbers. Replacement of the hard-to-implement decimal system (used in Charles Babbage's earlier design) by the simpler binary system meant that Zuse's machines were easier to build and potentially more reliable, given the technologies available at that time. The Z3 was Turing complete.

How many relays did the Z3 contain?

A: 2000


Problem: The 2007 gross state product was $44.9 billion, 45th in the nation. Its per capita personal income for 2007 was $40,042, ranking 15th in the nation. According to a 2013 study by Phoenix Marketing International, Alaska had the fifth-largest number of millionaires per capita in the United States, with a ratio of 6.75 percent. The oil and gas industry dominates the Alaskan economy, with more than 80% of the state's revenues derived from petroleum extraction. Alaska's main export product (excluding oil and natural gas) is seafood, primarily salmon, cod, Pollock and crab.
Beyond petroleum, what is Alaska's smallest export?

As prosperity began to return in the 1980s, the city was stunned by the Wah Mee massacre in 1983, when 13 people were killed in an illegal gambling club in the International District, Seattle's Chinatown. Beginning with Microsoft's 1979 move from Albuquerque, New Mexico to nearby Bellevue, Washington, Seattle and its suburbs became home to a number of technology companies including Amazon.com, RealNetworks, Nintendo of America, McCaw Cellular (now part of AT&T Mobility), VoiceStream (now T-Mobile), and biomedical corporations such as HeartStream (later purchased by Philips), Heart Technologies (later purchased by Boston Scientific), Physio-Control (later purchased by Medtronic), ZymoGenetics, ICOS (later purchased by Eli Lilly and Company) and Immunex (later purchased by Amgen). This success brought an influx of new residents with a population increase within city limits of almost 50,000 between 1990 and 2000, and saw Seattle's real estate become some of the most expensive in the country. In 1993, the movie Sleepless in Seattle brought the city further national attention. Many of the Seattle area's tech companies remained relatively strong, but the frenzied dot-com boom years ended in early 2001.
What violent act happened in Seattle's Chinatown in 1983?
A: Wah Mee massacre


Context and question: All the major British cities had flourishing department stores by the mid-or late nineteenth century. Increasingly, women became the major shoppers and middle-class households. Kendals (formerly Kendal Milne & Faulkner) in Manchester lays claim to being one of the first department stores and is still known to many of its customers as Kendal's, despite its 2005 name change to House of Fraser. The Manchester institution dates back to 1836 but had been trading as Watts Bazaar since 1796. At its zenith the store had buildings on both sides of Deansgate linked by a subterranean passage "Kendals Arcade" and an art nouveau tiled food hall. The store was especially known for its emphasis on quality and style over low prices giving it the nickname "the Harrods of the North", although this was due in part to Harrods acquiring the store in 1919. Other large Manchester stores included Paulden's (currently Debenhams) and Lewis's (now a Primark).
Who acquired the Manchester store in 1919? 
Answer: Harrods


Question: In 1897, Frank Shuman, a U.S. inventor, engineer and solar energy pioneer built a small demonstration solar engine that worked by reflecting solar energy onto square boxes filled with ether, which has a lower boiling point than water, and were fitted internally with black pipes which in turn powered a steam engine. In 1908 Shuman formed the Sun Power Company with the intent of building larger solar power plants. He, along with his technical advisor A.S.E. Ackermann and British physicist Sir Charles Vernon Boys, developed an improved system using mirrors to reflect solar energy upon collector boxes, increasing heating capacity to the extent that water could now be used instead of ether. Shuman then constructed a full-scale steam engine powered by low-pressure water, enabling him to patent the entire solar engine system by 1912.
Is there an answer to this question: In what year did solar engine build his solar engine?

Answer: 1897

Public Safety Canada’s Canadian Cyber Incident Response Centre (CCIRC) is responsible for mitigating and responding to threats to Canada’s critical infrastructure and cyber systems. The CCIRC provides support to mitigate cyber threats, technical support to respond and recover from targeted cyber attacks, and provides online tools for members of Canada’s critical infrastructure sectors. The CCIRC posts regular cyber security bulletins on the Public Safety Canada website. The CCIRC also operates an online reporting tool where individuals and organizations can report a cyber incident. Canada's Cyber Security Strategy is part of a larger, integrated approach to critical infrastructure protection, and functions as a counterpart document to the National Strategy and Action Plan for Critical Infrastructure.
What functions as a counterpart document to the National Strategy and Action Plan for Critical Infrastructure?
A:
Canada's Cyber Security Strategy
