Problem: Please answer a question about the following article about Antenna (radio):
Reflection of the original signal also occurs when it hits an extended conductive surface, in a fashion similar to a mirror. This effect can also be used to increase signal through the use of a reflector, normally placed behind the active element and spaced so the reflected signal reaches the element in-phase. Generally the reflector will remain highly reflective even if it is not solid; gaps less than 1⁄10 generally have little effect on the outcome. For this reason, reflectors often take the form of wire meshes or rows of passive elements, which makes them lighter and less subject to wind. The parabolic reflector is perhaps the best known example of a reflector-based antenna, which has an effective area far greater than the active element alone.
What allowance can be made for gaps without loss of performance?
A: less than 1⁄10
Problem: Please answer a question about the following article about Universal Studios:
Universal's 1936 Show Boat (released a little over a month later) became a critical and financial success, it was not enough to save the Laemmles' involvement with the studio. They were unceremoniously removed from the company they had founded. Because the Laemmles personally oversaw production, Show Boat was released (despite the takeover) with Carl Laemmle and Carl Laemmle Jr.'s names on the credits and in the advertising campaign of the film. Standard Capital's J. Cheever Cowdin had taken over as president and chairman of the board of directors, and instituted severe cuts in production budgets. Gone were the big ambitions, and though Universal had a few big names under contract, those it had been cultivating, like William Wyler and Margaret Sullavan, left.
Who became president of Universal after the Standard Capital takeover?
A: J. Cheever Cowdin
Problem: Please answer a question about the following article about Late Middle Ages:
The term "Late Middle Ages" refers to one of the three periods of the Middle Ages, along with the Early Middle Ages and the High Middle Ages. Leonardo Bruni was the first historian to use tripartite periodization in his History of the Florentine People (1442). Flavio Biondo used a similar framework in Decades of History from the Deterioration of the Roman Empire (1439–1453). Tripartite periodization became standard after the German historian Christoph Cellarius published Universal History Divided into an Ancient, Medieval, and New Period (1683).
What is the name for the division of the periods of history introduced by Bruni?
A: tripartite periodization
Problem: Please answer a question about the following article about Sino-Tibetan relations during the Ming dynasty:
Wang and Nyima state that after the official title "Education Minister" was granted to Tai Situ Changchub Gyaltsen (1302–1364) by the Yuan court, this title appeared frequently with his name in various Tibetan texts, while his Tibetan title "Degsi" (sic properly sde-srid or desi) is seldom mentioned. Wang and Nyima take this to mean that "even in the later period of the Yuan dynasty, the Yuan imperial court and the Phagmodrupa Dynasty maintained a Central-local government relation." The Tai Situpa is even supposed to have written in his will: "In the past I received loving care from the emperor in the east. If the emperor continues to care for us, please follow his edicts and the imperial envoy should be well received."
Who wrote in their will that they received loving care from the emperor in the east?
A:
The Tai Situpa
