Problem: George VI:

Throughout the war, the King and Queen provided morale-boosting visits throughout the United Kingdom, visiting bomb sites, munitions factories, and troops. The King visited military forces abroad in France in December 1939, North Africa and Malta in June 1943, Normandy in June 1944, southern Italy in July 1944, and the Low Countries in October 1944. Their high public profile and apparently indefatigable determination secured their place as symbols of national resistance. At a social function in 1944, Chief of the Imperial General Staff Sir Alan Brooke, revealed that every time he met Field Marshal Bernard Montgomery he thought he was after his job. The King replied: "You should worry, when I meet him, I always think he's after mine!"

What improved when the King and Queen visited different military sites?

A: morale


Problem: In 1971, Akira Endo, a Japanese biochemist working for the pharmaceutical company Sankyo, identified mevastatin (ML-236B), a molecule produced by the fungus Penicillium citrinum, as an inhibitor of HMG-CoA reductase, a critical enzyme used by the body to produce cholesterol. Animal trials showed very good inhibitory effect as in clinical trials, however a long term study in dogs found toxic effects at higher doses and as a result mevastatin was believed to be too toxic for human use. Mevastatin was never marketed, because of its adverse effects of tumors, muscle deterioration, and sometimes death in laboratory dogs.
In what year was Penicillium discovered?

Context and question: The opening years of the 1980s saw a number of changes in personnel and direction of established hard rock acts, including the deaths of Bon Scott, the lead singer of AC/DC, and John Bonham, drummer with Led Zeppelin. Whereas Zeppelin broke up almost immediately afterwards, AC/DC pressed on, recording the album Back in Black (1980) with their new lead singer, Brian Johnson. It became the fifth-highest-selling album of all time in the US and the second-highest-selling album in the world. Black Sabbath had split with original singer Ozzy Osbourne in 1979 and replaced him with Ronnie James Dio, formerly of Rainbow, giving the band a new sound and a period of creativity and popularity beginning with Heaven and Hell (1980). Osbourne embarked on a solo career with Blizzard of Ozz (1980), featuring American guitarist Randy Rhoads. Some bands, such as Queen, moved away from their hard rock roots and more towards pop rock, while others, including Rush with Moving Pictures (1981), began to return to a hard rock sound. The creation of thrash metal, which mixed heavy metal with elements of hardcore punk from about 1982, particularly by Metallica, Anthrax, Megadeth and Slayer, helped to create extreme metal and further remove the style from hard rock, although a number of these bands or their members would continue to record some songs closer to a hard rock sound. Kiss moved away from their hard rock roots toward pop metal: firstly removing their makeup in 1983 for their Lick It Up album, and then adopting the visual and sound of glam metal for their 1984 release, Animalize, both of which marked a return to commercial success. Pat Benatar was one of the first women to achieve commercial success in hard rock, with three successive Top 5 albums between 1980 and 1982.
Who quit the band Led Zeppelin to move to another band?
Answer: unanswerable


Question: Armenians enjoy many different native and foreign foods. Arguably the favorite food is khorovats an Armenian-styled barbecue. Lavash is a very popular Armenian flat bread, and Armenian paklava is a popular dessert made from filo dough. Other famous Armenian foods include the kabob (a skewer of marinated roasted meat and vegetables), various dolmas (minced lamb, or beef meat and rice wrapped in grape leaves, cabbage leaves, or stuffed into hollowed vegetables), and pilaf, a rice dish. Also, ghapama, a rice-stuffed pumpkin dish, and many different salads are popular in Armenian culture. Fruits play a large part in the Armenian diet. Apricots (Prunus armeniaca, also known as Armenian Plum) have been grown in Armenia for centuries and have a reputation for having an especially good flavor. Peaches are popular as well, as are grapes, figs, pomegranates, and melons. Preserves are made from many fruits, including cornelian cherries, young walnuts, sea buckthorn, mulberries, sour cherries, and many others.
Is there an answer to this question: What reputation do cornelian cherries have?

Problem: Warsaw Pact:

The strategy behind the formation of the Warsaw Pact was driven by the desire of the Soviet Union to dominate Central and Eastern Europe. This policy was driven by ideological and geostrategic reasons. Ideologically, the Soviet Union arrogated the right to define socialism and communism and act as the leader of the global socialist movement. A corollary to this idea was the necessity of intervention if a country appeared to be violating core socialist ideas and Communist Party functions, which was explicitly stated in the Brezhnev Doctrine. Geostrategic principles also drove the Soviet Union to prevent invasion of its territory by Western European powers.

Who wanted to dominate Western and Eastern Europe?
