Problem: Railway electrification system:

In the Soviet Union, in the 1970s, a comparison was made between systems electrified at 3 kV DC and 25 kV AC (50 Hz). The results showed that percentage losses in the overhead wires (catenary and contact wires) was over 3 times greater for 3 kV DC than for 25 kV AC. But when the conversion losses were all taken into account and added to overhead wire losses (including cooling blower energy) the 25 kV AC lost a somewhat higher percent of energy than for 3 kV DC. Thus in spite of the much higher losses in the catenary, the 3 kV DC was a little more energy efficient than AC in providing energy from the USSR power grid to the terminals of the traction motors (all DC at that time). While both systems use energy in converting higher voltage AC from the USSR's power grid to lower voltage DC, the conversions for the DC system all took place (at higher efficiency) in the railway substation, while most of the conversion for the AC system took place inside the locomotive (at lower efficiency). Consider also that it takes energy to constantly move this mobile conversion hardware over the rails while the stationary hardware in the railway substation doesn't incur this energy cost. For more details see: Wiki: Soviet Union DC vs. AC.

What two systems were compare in the Soviet Union in 1970?
---
A: 3 kV DC and 25 kV AC (50 Hz


Problem: The American Idol Songwriter contest was also held this season. From ten of the most popular submissions, each of the final two contestants chose a song to perform, although neither of their selections was used as the "coronation song". The winning song, "The Time of My Life", was recorded by David Cook and released on May 22, 2008.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Many globally popular sports had modern rules codified in the British Isles, including golf, association football, cricket, rugby, snooker and darts, as well as many minor sports such as croquet, bowls, pitch and putt, water polo and handball. A number of sports are popular throughout the British Isles, the most prominent of which is association football. While this is organised separately in different national associations, leagues and national teams, even within the UK, it is a common passion in all parts of the islands. Rugby union is also widely enjoyed across the islands with four national teams from England, Ireland, Scotland and Wales. The British and Irish Lions is a team chosen from each national team and undertakes tours of the southern hemisphere rugby playing nations every four years. Ireland play as a united team, represented by players from both Northern Ireland and the Republic. These national rugby teams play each other each year for the Triple Crown as part of the Six Nations Championship. Also since 2001 the professional club teams of Ireland, Scotland, Wales and Italy compete against each other in the RaboDirect Pro12.
How many national Ruby teams are there in the United Kingdom?
A: four


Context and question: In the revival movement France held a foremost place, owing to the reputation and convincing power of the orator, Jean-Baptiste Henri Lacordaire (1802–1861). He took the habit of a Friar Preacher at Rome (1839), and the province of France was canonically erected in 1850. From this province were detached the province of Lyon, called Occitania (1862), that of Toulouse (1869), and that of Canada (1909). The French restoration likewise furnished many laborers to other provinces, to assist in their organization and progress. From it came the master general who remained longest at the head of the administration during the 19th century, Père Vincent Jandel (1850–1872). Here should be mentioned the province of St. Joseph in the United States. Founded in 1805 by Edward Fenwick, afterwards first Bishop of Cincinnati, Ohio (1821–1832), this province has developed slowly, but now ranks among the most flourishing and active provinces of the order. In 1910 it numbered seventeen convents or secondary houses. In 1905, it established a large house of studies at Washington, D.C., called the Dominican House of Studies. There are now four Dominican provinces in the United States.
What title did Pere Vincent Jandel hold during this time?
Answer: master general


Question: Weeks after ending the Sex Pistols, Lydon formed the experimental group Public Image Ltd and declared the project to be "anti music of any kind". Public Image and other acts such as the Pop Group and the Slits had begun experimenting with dance music, dub production techniques and the avant-garde, while punk-indebted Manchester acts such as Joy Division, The Fall and A Certain Ratio developed unique styles which drew on a similarly disparate range of influences across music and modernist literature. Bands such as Scritti Politti, Gang of Four and This Heat incorporated Leftist political philosophy and their own art school studies in their work.
Is there an answer to this question: What kind of group was Public Image Ltd?

Answer: "anti music of any kind"
