Here is a question about this article: Chen Qingying, Professor of History and Director of the History Studies Institute under the China Tibetology Research Center in Beijing, writes that the Ming court conferred new official positions on ex-Yuan Tibetan leaders of the Phachu Kargyu and granted them lower-ranking positions. Of the county (zong or dzong) leaders of Neiwo Zong and Renbam Zong, Chen states that when "the Emperor learned the actual situation of the Phachu Kargyu, the Ming court then appointed the main Zong leaders to be senior officers of the Senior Command of Dbus and Gtsang." The official posts that the Ming court established in Tibet, such as senior and junior commanders, offices of Qianhu (in charge of 1,000 households), and offices of Wanhu (in charge of 10,000 households), were all hereditary positions according to Chen, but he asserts that "the succession of some important posts still had to be approved by the emperor," while old imperial mandates had to be returned to the Ming court for renewal.
What is the answer to this question: Who was the Director of the History Studies Institute?
****
So... Chen Qingying

The problem: Answer a question about this article:
In 550 BC, Cyrus the Great, son of Mandane and Cambyses I, took over the Median Empire, and founded the Achaemenid Empire by unifying other city states. The conquest of Media was a result of what is called the Persian Revolt. The brouhaha was initially triggered by the actions of the Median ruler Astyages, and was quickly spread to other provinces, as they allied with the Persians. Later conquests under Cyrus and his successors expanded the empire to include Lydia, Babylon, Egypt, parts of the Balkans and Eastern Europe proper, as well as the lands to the west of the Indus and Oxus rivers.
When did Cyrus the Great found the Achaemenid Empire?
****
The answer: 550 BC

Problem: Immediately after reading Price's sermon, Burke wrote a draft of what eventually became, Reflections on the Revolution in France. On 13 February 1790, a notice in the press said that shortly, Burke would publish a pamphlet on the Revolution and its British supporters, however he spent the year revising and expanding it. On 1 November he finally published the Reflections and it was an immediate best-seller. Priced at five shillings, it was more expensive than most political pamphlets, but by the end of 1790, it had gone through ten printings and sold approximately 17,500 copies. A French translation appeared on 29 November and on 30 November the translator, Pierre-Gaeton Dupont, wrote to Burke saying 2,500 copies had already been sold. The French translation ran to ten printings by June 1791.
How many copies did Reflections on the Revolution in France sell in 2 months?
The answer is the following: 17,500

Input: Article: Due to reciprocity (discussed above) the gain of an antenna used for transmitting must be proportional to its effective area when used for receiving. Consider an antenna with no loss, that is, one whose electrical efficiency is 100%. It can be shown that its effective area averaged over all directions must be equal to 2/4, the wavelength squared divided by 4. Gain is defined such that the average gain over all directions for an antenna with 100% electrical efficiency is equal to 1. Therefore, the effective area Aeff in terms of the gain G in a given direction is given by:

Now answer this question: hat could an antenna with complete electrical efficiency be said to have?

Output:
1
