Problem: 51st state:

Poland has historically been staunchly pro-American, dating back to General Tadeusz Kosciuszko and Casimir Pulaski's involvement in the American Revolution. This pro-American stance was reinforced following favorable American intervention in World War I (leading to the creation of an independent Poland) and the Cold War (culminating in a Polish state independent of Soviet influence). Poland contributed a large force to the "Coalition of the Willing" in Iraq. A quote referring to Poland as "the 51st state" has been attributed to James Pavitt, then Central Intelligence Agency Deputy Director for Operations, especially in connection to extraordinary rendition.

What culminated in a Polish state dependent on Soviet influence?

Problem: Notre Dame alumni work in various fields. Alumni working in political fields include state governors, members of the United States Congress, and former United States Secretary of State Condoleezza Rice. A notable alumnus of the College of Science is Medicine Nobel Prize winner Eric F. Wieschaus. A number of university heads are alumni, including Notre Dame's current president, the Rev. John Jenkins. Additionally, many alumni are in the media, including talk show hosts Regis Philbin and Phil Donahue, and television and radio personalities such as Mike Golic and Hannah Storm. With the university having high profile sports teams itself, a number of alumni went on to become involved in athletics outside the university, including professional baseball, basketball, football, and ice hockey players, such as Joe Theismann, Joe Montana, Tim Brown, Ross Browner, Rocket Ismail, Ruth Riley, Jeff Samardzija, Jerome Bettis, Brett Lebda, Olympic gold medalist Mariel Zagunis, professional boxer Mike Lee, former football coaches such as Charlie Weis, Frank Leahy and Knute Rockne, and Basketball Hall of Famers Austin Carr and Adrian Dantley. Other notable alumni include prominent businessman Edward J. DeBartolo, Jr. and astronaut Jim Wetherbee.

Context and question: Home-based manufacturing operations were active year round. Families willingly deployed their children in these income generating home enterprises. In many cases, men worked from home. In France, over 58 percent of garment workers operated out of their homes; in Germany, the number of full-time home operations nearly doubled between 1882 and 1907; and in the United States, millions of families operated out of home seven days a week, year round to produce garments, shoes, artificial flowers, feathers, match boxes, toys, umbrellas and other products. Children aged 514 worked alongside the parents. Home-based operations and child labour in Australia, Britain, Austria and other parts of the world was common. Rural areas similarly saw families deploying their children in agriculture. In 1946, Frieda Miller - then Director of United States Department of Labour - told the International Labour Organisation that these home-based operations offered, "low wages, long hours, child labour, unhealthy and insanitary working conditions."
What time were home manufactoring activities for children taking place?
Answer: year round

Question: Despite repeated efforts by the Tajik government to improve and expand health care, the system remains extremely underdeveloped and poor, with severe shortages of medical supplies. The state's Ministry of Labor and Social Welfare reported that 104,272 disabled people are registered in Tajikistan (2000). This group of people suffers most from poverty in Tajikistan. The government of Tajikistan and the World Bank considered activities to support this part of the population described in the World Bank's Poverty Reduction Strategy Paper. Public expenditure on health was at 1% of the GDP in 2004.
Is there an answer to this question: How many disabled people are unregistered in Tajikistan?

Answer: unanswerable

Problem: Incandescent light bulb:

A variation of the incandescent lamp did not use a hot wire filament, but instead used an arc struck on a spherical bead electrode to produce heat. The electrode then became incandescent, with the arc contributing little to the light produced. Such lamps were used for projection or illumination for scientific instruments such as microscopes. These arc lamps ran on relatively low voltages and incorporated tungsten filaments to start ionization within the envelope. They provided the intense concentrated light of an arc lamp but were easier to operate. Developed around 1915, these lamps were displaced by mercury and xenon arc lamps.

What was a common application for this type of bulb?
---
A:
scientific instruments such as microscopes
