Here is a question about this article: Universal could seldom afford its own stable of stars, and often borrowed talent from other studios, or hired freelance actors. In addition to Stewart and Dietrich, Margaret Sullavan, and Bing Crosby were two of the major names that made a couple of pictures for Universal during this period. Some stars came from radio, including Edgar Bergen, W. C. Fields, and the comedy team of Abbott and Costello (Bud Abbott and Lou Costello). Abbott and Costello's military comedy Buck Privates (1941) gave the former burlesque comedians a national and international profile.
What is the answer to this question: What military comedy did Bud Abbott and Lou Costello star in?
****
So... Buck Privates


The problem: Answer a question about this article:
Active solar techniques use photovoltaics, concentrated solar power, solar thermal collectors, pumps, and fans to convert sunlight into useful outputs. Passive solar techniques include selecting materials with favorable thermal properties, designing spaces that naturally circulate air, and referencing the position of a building to the Sun. Active solar technologies increase the supply of energy and are considered supply side technologies, while passive solar technologies reduce the need for alternate resources and are generally considered demand side technologies.
What is an active solar technique used to generate energy?
****
The answer: designing spaces that naturally circulate air


Problem: Please answer a question about the following article about Planck constant:
The theoretical difficulties arise from the fact that all of the methods except the X-ray crystal density method rely on the theoretical basis of the Josephson effect and the quantum Hall effect. If these theories are slightly inaccurate – though there is no evidence at present to suggest they are – the methods would not give accurate values for the Planck constant. More importantly, the values of the Planck constant obtained in this way cannot be used as tests of the theories without falling into a circular argument. Fortunately, there are other statistical ways of testing the theories, and the theories have yet to be refuted.
What is the saving grace of relying on these theories?
A: there are other statistical ways of testing the theories, and the theories have yet to be refuted.

 North Korea: The event was held in Pyongyang on April 28. It was the first time that the Olympic torch has traveled to North Korea. A crowd of thousands waving pink paper flowers and small flags with the Beijing Olympics logo were organized by the authoritarian regime watched the beginning of the relay in Pyongyang, some waving Chinese flags. The event was presided over by the head of the country's parliament, Kim Yong Nam. The North, an ally of China, has been critical of disruptions to the torch relay elsewhere and has supported Beijing in its actions against protests in Tibet. Kim passed the torch to the first runner Pak Du Ik, who played on North Korea's 1966 World Cup soccer team, as he began the 19-kilometre route through Pyongyang. The relay began from the large sculpted flame of the obelisk of the Juche Tower, which commemorates the national ideology of Juche, or "self-reliance", created by the country's late founding President Kim Il Sung, father of leader Kim Jong Il, who did not attend.

Who was the first torchbearer in North Korea?
Answer:
Pak Du Ik
