Input: Han dynasty
Emperor Zhang's (r. 7588 AD) reign came to be viewed by later Eastern Han scholars as the high point of the dynastic house. Subsequent reigns were increasingly marked by eunuch intervention in court politics and their involvement in the violent power struggles of the imperial consort clans. With the aid of the eunuch Zheng Zhong (d. 107 AD), Emperor He (r. 88105 AD) had Empress Dowager Dou (d. 97 AD) put under house arrest and her clan stripped of power. This was in revenge for Dou's purging of the clan of his natural motherConsort Liangand then concealing her identity from him. After Emperor He's death, his wife Empress Deng Sui (d. 121 AD) managed state affairs as the regent empress dowager during a turbulent financial crisis and widespread Qiang rebellion that lasted from 107 to 118 AD.

When did Emperor He's reign end?
Output: 105 AD

Input: Article: Efforts by local kings to fight the invaders led to the formation of new political entities. In Anglo-Saxon England, King Alfred the Great (r. 871899) came to an agreement with the Viking invaders in the late 9th century, resulting in Danish settlements in Northumbria, Mercia, and parts of East Anglia. By the middle of the 10th century, Alfred's successors had conquered Northumbria, and restored English control over most of the southern part of Great Britain. In northern Britain, Kenneth MacAlpin (d. c. 860) united the Picts and the Scots into the Kingdom of Alba. In the early 10th century, the Ottonian dynasty had established itself in Germany, and was engaged in driving back the Magyars. Its efforts culminated in the coronation in 962 of Otto I (r. 936973) as Holy Roman Emperor. In 972, he secured recognition of his title by the Byzantine Empire, which he sealed with the marriage of his son Otto II (r. 967983) to Theophanu (d. 991), daughter of an earlier Byzantine Emperor Romanos II (r. 959963). By the late 10th century Italy had been drawn into the Ottonian sphere after a period of instability; Otto III (r. 9961002) spent much of his later reign in the kingdom. The western Frankish kingdom was more fragmented, and although kings remained nominally in charge, much of the political power devolved to the local lords.

Now answer this question: Of what dynasty was Otto I a member?

Output: Ottonian dynasty

Article: At the beginning of the 13th century, there were reasonably accurate Latin translations of the main works of almost all the intellectually crucial ancient authors, allowing a sound transfer of scientific ideas via both the universities and the monasteries. By then, the natural philosophy contained in these texts began to be extended by notable scholastics such as Robert Grosseteste, Roger Bacon, Albertus Magnus and Duns Scotus. Precursors of the modern scientific method, influenced by earlier contributions of the Islamic world, can be seen already in Grosseteste's emphasis on mathematics as a way to understand nature, and in the empirical approach admired by Bacon, particularly in his Opus Majus. Pierre Duhem's provocative thesis of the Catholic Church's Condemnation of 1277 led to the study of medieval science as a serious discipline, "but no one in the field any longer endorses his view that modern science started in 1277". However, many scholars agree with Duhem's view that the Middle Ages were a period of important scientific developments.

Question: Who favored empirical methods?
Ans: Bacon

Here is a question about this article: As they grew older Madonna and her sisters would feel deep sadness as the vivid memory of their mother began drifting farther from them. They would study pictures of her and come to think that she resembled poet Anne Sexton and Hollywood actresses. This would later raise Madonna's interest in poetry, with Sylvia Plath being her favourite. Later, Madonna commented: "We were all wounded in one way or another by [her death], and then we spent the rest of our lives reacting to it or dealing with it or trying to turn into something else. The anguish of losing my mom left me with a certain kind of loneliness and an incredible longing for something. If I hadn't had that emptiness, I wouldn't have been so driven. Her death had a lot to do with me sayingafter I got over my heartacheI'm going to be really strong if I can't have my mother. I'm going to take care of myself." Taraborrelli felt that in time, no doubt because of the devastation she felt, Madonna would never again allow herself, or even her daughter, to feel as abandoned as she had felt when her mother died. "Her death had taught [Madonna] a valuable lesson, that she would have to remain strong for herself because, she feared weaknessparticularly her ownand wanted to be the queen of her own castle."
What is the answer to this question: Who felt that her mother death was the driving force behind her success?
****
So... Madonna

The problem: Answer a question about this article:
Resonant antennas are expected to be used around a particular resonant frequency; an antenna must therefore be built or ordered to match the frequency range of the intended application. A particular antenna design will present a particular feedpoint impedance. While this may affect the choice of an antenna, an antenna's impedance can also be adapted to the desired impedance level of a system using a matching network while maintaining the other characteristics (except for a possible loss of efficiency).
Which antenna type would be best for a project requiring a specific frequency?
****
The answer: Resonant antennas

The problem: Answer a question about this article:
The above explanation is merely a simple introduction to vacuum pumping, and is not representative of the entire range of pumps in use. Many variations of the positive displacement pump have been developed, and many other pump designs rely on fundamentally different principles. Momentum transfer pumps, which bear some similarities to dynamic pumps used at higher pressures, can achieve much higher quality vacuums than positive displacement pumps. Entrapment pumps can capture gases in a solid or absorbed state, often with no moving parts, no seals and no vibration. None of these pumps are universal; each type has important performance limitations. They all share a difficulty in pumping low molecular weight gases, especially hydrogen, helium, and neon.
What pump can capture gases in a solid or absorbed state?
****
The answer:
Entrapment pumps
