Problem: Portugal:

Portuguese cuisine is diverse. The Portuguese consume a lot of dry cod (bacalhau in Portuguese), for which there are hundreds of recipes. There are more than enough bacalhau dishes for each day of the year. Two other popular fish recipes are grilled sardines and caldeirada, a potato-based stew that can be made from several types of fish. Typical Portuguese meat recipes, that may be made out of beef, pork, lamb, or chicken, include cozido a portuguesa, feijoada, frango de churrasco, leitao (roast suckling pig) and carne de porco a alentejana. A very popular northern dish is the arroz de sarrabulho (rice stewed in pigs blood) or the arroz de cabidela (rice and chickens meat stewed in chickens blood).

Problem: Circadian rhythm:

Studies by Nathaniel Kleitman in 1938 and by Derk-Jan Dijk and Charles Czeisler in the 1990s put human subjects on enforced 28-hour sleepwake cycles, in constant dim light and with other time cues suppressed, for over a month. Because normal people cannot entrain to a 28-hour day in dim light if at all,[citation needed] this is referred to as a forced desynchrony protocol. Sleep and wake episodes are uncoupled from the endogenous circadian period of about 24.18 hours and researchers are allowed to assess the effects of circadian phase on aspects of sleep and wakefulness including sleep latency and other functions.[page needed]

What is this forced type of study called?
---
A: forced desynchrony

Problem: Strasbourg:

Many people from Strasbourg were incorporated in the German Army against their will, and were sent to the eastern front, those young men and women were called Malgre-nous. Many tried to escape from the incorporation, join the French Resistance, or desert the Wehrmacht but many couldn't because they were running the risk of having their families sent to work or concentration camps by the Germans. Many of these men, especially those who did not answer the call immediately, were pressured to "volunteer" for service with the SS, often by direct threats on their families. This threat obliged the majority of them to remain in the German army. After the war, the few that survived were often accused of being traitors or collaborationists, because this tough situation was not known in the rest of France, and they had to face the incomprehension of many. In July 1944, 1500 malgre-nous were released from Soviet captivity and sent to Algiers, where they joined the Free French Forces. Nowadays history recognizes the suffering of those people, and museums, public discussions and memorials have been built to commemorate this terrible period of history of this part of Eastern France (Alsace and Moselle). Liberation of Strasbourg took place on 23 November 1944.

How many Malgre-nous were forced to join the German forces?
---
A: unanswerable

Problem: Mandolin:

Monroe's style involved playing lead melodies in the style of a fiddler, and also a percussive chording sound referred to as "the chop" for the sound made by the quickly struck and muted strings. He also perfected a sparse, percussive blues style, especially up the neck in keys that had not been used much in country music, notably B and E. He emphasized a powerful, syncopated right hand at the expense of left-hand virtuosity. Monroe's most influential follower of the second generation is Frank Wakefield and nowadays Mike Compton of the Nashville Bluegrass Band and David Long, who often tour as a duet. Tiny Moore of the Texas Playboys developed an electric five-string mandolin and helped popularize the instrument in Western Swing music.

What chording feeling was Monroe popular for?

A:
