Problem: Incandescent light bulb:

Very small lamps may have the filament support wires extended through the base of the lamp, and can be directly soldered to a printed circuit board for connections. Some reflector-type lamps include screw terminals for connection of wires. Most lamps have metal bases that fit in a socket to support the lamp and conduct current to the filament wires. In the late 19th century, manufacturers introduced a multitude of incompatible lamp bases. General Electric introduced standard base sizes for tungsten incandescent lamps under the Mazda trademark in 1909. This standard was soon adopted across the US, and the Mazda name was used by many manufacturers under license through 1945. Today most incandescent lamps for general lighting service use an Edison screw in candelabra, intermediate, or standard or mogul sizes, or double contact bayonet base. Technical standards for lamp bases include ANSI standard C81.67 and IEC standard 60061-1 for common commercial lamp sizes, to ensure interchangeablitity between different manufacturer's products. Bayonet base lamps are frequently used in automotive lamps to resist loosening due to vibration. A bipin base is often used for halogen or reflector lamps.

What year was the Mazda trademark rejected?

A: unanswerable

Problem: One of the first demonstrations of the ability for telecommunications to help sign language users communicate with each other occurred when AT&T's videophone (trademarked as the "Picturephone") was introduced to the public at the 1964 New York World's Fair two deaf users were able to communicate freely with each other between the fair and another city. Various universities and other organizations, including British Telecom's Martlesham facility, have also conducted extensive research on signing via videotelephony. The use of sign language via videotelephony was hampered for many years due to the difficulty of its use over slow analogue copper phone lines, coupled with the high cost of better quality ISDN (data) phone lines. Those factors largely disappeared with the introduction of more efficient video codecs and the advent of lower cost high-speed ISDN data and IP (Internet) services in the 1990s.
In what decade were more efficient ways of using sign language via video-telephony developed?

Answer: 1990s

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On 15 May 1947, the General Assembly of the newly formed United Nations resolved that a committee, United Nations Special Committee on Palestine (UNSCOP), be created "to prepare for consideration at the next regular session of the Assembly a report on the question of Palestine". In the Report of the Committee dated 3 September 1947 to the UN General Assembly, the majority of the Committee in Chapter VI proposed a plan to replace the British Mandate with "an independent Arab State, an independent Jewish State, and the City of Jerusalem ... the last to be under an International Trusteeship System". On 29 November 1947, the General Assembly adopted a resolution recommending the adoption and implementation of the Plan of Partition with Economic Union as Resolution 181 (II). The Plan attached to the resolution was essentially that proposed by the majority of the Committee in the Report of 3 September 1947.
When was the UNSCOP formed?
A: 15 May 1947

Context and question: The company aims to reduce its external environmental impact through energy-efficient evolution of products, and also reduce its direct operational impact through energy-efficiency programs. Internal energy-efficiency programs reportedly save the company more than $3 million annually in energy-cost savings. The largest component of the company's internal energy-efficiency savings comes through PC power management: the company expects to save $1.8 million in energy costs through using specialized energy-management software on a network of 50,000 PCs.
What does Dell aim to increase by creating energy efficient products?
Answer: unanswerable

Question: U.S. submarines, as well as some British and Dutch vessels, operating from bases at Cavite in the Philippines (194142); Fremantle and Brisbane, Australia; Pearl Harbor; Trincomalee, Ceylon; Midway; and later Guam, played a major role in defeating Japan, even though submarines made up a small proportion of the Allied naviesless than two percent in the case of the US Navy. Submarines strangled Japan by sinking its merchant fleet, intercepting many troop transports, and cutting off nearly all the oil imports essential to weapons production and military operations. By early 1945 Japanese oil supplies were so limited that its fleet was virtually stranded.
Is there an answer to this question: What did submarines sinking Japanese ships do?

Answer: strangled Japan

Problem: Pope John XXIII:

On 12 January 1953, he was appointed Patriarch of Venice and, accordingly, raised to the rank of Cardinal-Priest of Santa Prisca by Pope Pius XII. Roncalli left France for Venice on 23 February 1953 stopping briefly in Milan and then to Rome. On 15 March 1953, he took possession of his new diocese in Venice. As a sign of his esteem, the President of France, Vincent Auriol, claimed the ancient privilege possessed by French monarchs and bestowed the red biretta on Roncalli at a ceremony in the Elysee Palace. It was around this time that he, with the aid of Monsignor Bruno Heim, formed his coat of arms with a lion of Saint Mark on a white ground. Auriol also awarded Roncalli three months later with the award of Commander of the Legion of Honour.

Pope Pius XII raised him to what rank?

A:
Cardinal-Priest of Santa Prisca
