Problem: Film speed:

Before the advent of the ASA system, the system of Weston film speed ratings was introduced by Edward Faraday Weston (1878–1971) and his father Dr. Edward Weston (1850–1936), a British-born electrical engineer, industrialist and founder of the US-based Weston Electrical Instrument Corporation, with the Weston model 617, one of the earliest photo-electric exposure meters, in August 1932. The meter and film rating system were invented by William Nelson Goodwin, Jr., who worked for them and later received a Howard N. Potts Medal for his contributions to engineering.

When was the Weston model 617 created?
---
A: August 1932


Problem: The NES uses a custom-made Picture Processing Unit (PPU) developed by Ricoh. All variations of the PPU feature 2 kB of video RAM, 256 bytes of on-die "object attribute memory" (OAM) to store the positions, colors, and tile indices of up to 64 sprites on the screen, and 28 bytes of on-die palette RAM to allow selection of background and sprite colors. The console's 2 kB of onboard RAM may be used for tile maps and attributes on the NES board and 8 kB of tile pattern ROM or RAM may be included on a cartridge. The system has an available color palette of 48 colors and 6 grays. Up to 25 simultaneous colors may be used without writing new values mid-frame: a background color, four sets of three tile colors and four sets of three sprite colors. The NES palette is based on NTSC rather than RGB values. A total of 64 sprites may be displayed onscreen at a given time without reloading sprites mid-screen. The standard display resolution of the NES is 256 horizontal pixels by 240 vertical pixels.
 How many mb of Video RAM did the PPU have?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Timber was the chief building material during the Han dynasty; it was used to build palace halls, multi-story residential towers and halls and single-story houses. Because wood decays rapidly, the only remaining evidence of Han wooden architecture is a collection of scattered ceramic roof tiles. The oldest surviving wooden halls in China date to the Tang dynasty (618–907 AD). Architectural historian Robert L. Thorp points out the scarcity of Han-era archaeological remains, and claims that often unreliable Han-era literary and artistic sources are used by historians for clues about lost Han architecture.
What was the primary component of a palace hall during the Han dynasty?
A: Timber


Context and question: Yale has had many financial supporters, but some stand out by the magnitude or timeliness of their contributions. Among those who have made large donations commemorated at the university are: Elihu Yale; Jeremiah Dummer; the Harkness family (Edward, Anna, and William); the Beinecke family (Edwin, Frederick, and Walter); John William Sterling; Payne Whitney; Joseph E. Sheffield, Paul Mellon, Charles B. G. Murphy and William K. Lanman. The Yale Class of 1954, led by Richard Gilder, donated $70 million in commemoration of their 50th reunion. Charles B. Johnson, a 1954 graduate of Yale College, pledged a $250 million gift in 2013 to support of the construction of two new residential colleges.
How much didn't Charles B. Johnson pledge to Yale in 2013?
Answer: unanswerable


Question: From 1938 until 1995, the U.S. Supreme Court did not invalidate any federal statute as exceeding Congress' power under the Commerce Clause. Most actions by the federal government can find some legal support among the express powers, such as the Commerce Clause, whose applicability has been narrowed by the Supreme Court in recent years. In 1995 the Supreme Court rejected the Gun-Free School Zones Act in the Lopez decision, and also rejected the civil remedy portion of the Violence Against Women Act of 1994 in the United States v. Morrison decision. Recently, the Commerce Clause was interpreted to include marijuana laws in the Gonzales v. Raich decision.
Is there an answer to this question: What happened between 1938 to 1959?

Answer: unanswerable


Question: On 29 May 1842, Victoria was riding in a carriage along The Mall, London, when John Francis aimed a pistol at her but the gun did not fire; he escaped. The following day, Victoria drove the same route, though faster and with a greater escort, in a deliberate attempt to provoke Francis to take a second aim and catch him in the act. As expected, Francis shot at her, but he was seized by plain-clothes policemen, and convicted of high treason. On 3 July, two days after Francis's death sentence was commuted to transportation for life, John William Bean also tried to fire a pistol at the Queen, but it was loaded only with paper and tobacco and had too little charge. Edward Oxford felt that the attempts were encouraged by his acquittal in 1840. Bean was sentenced to 18 months in jail. In a similar attack in 1849, unemployed Irishman William Hamilton fired a powder-filled pistol at Victoria's carriage as it passed along Constitution Hill, London. In 1850, the Queen did sustain injury when she was assaulted by a possibly insane ex-army officer, Robert Pate. As Victoria was riding in a carriage, Pate struck her with his cane, crushing her bonnet and bruising her forehead. Both Hamilton and Pate were sentenced to seven years' transportation.
Is there an answer to this question: What was the name of the man that tried to shoot Queen Victoria?

Answer:
John Francis
