Problem: Please answer a question about the following article about Transistor:
BJTs have three terminals, corresponding to the three layers of semiconductoran emitter, a base, and a collector. They are useful in amplifiers because the currents at the emitter and collector are controllable by a relatively small base current. In an npn transistor operating in the active region, the emitterbase junction is forward biased (electrons and holes recombine at the junction), and electrons are injected into the base region. Because the base is narrow, most of these electrons will diffuse into the reverse-biased (electrons and holes are formed at, and move away from the junction) basecollector junction and be swept into the collector; perhaps one-hundredth of the electrons will recombine in the base, which is the dominant mechanism in the base current. By controlling the number of electrons that can leave the base, the number of electrons entering the collector can be controlled. Collector current is approximately (common-emitter current gain) times the base current. It is typically greater than 100 for small-signal transistors but can be smaller in transistors designed for high-power applications.
What are the layers of semiconductor in a BJT?
A: an emitter, a base, and a collector

The HMWSSB regulates rainwater harvesting, sewerage services and water supply, which is sourced from several dams located in the suburbs. In 2005, the HMWSSB started operating a 116-kilometre-long (72 mi) water supply pipeline from Nagarjuna Sagar Dam to meet increasing demand. The Telangana Southern Power Distribution Company Limited manages electricity supply. As of October 2014, there were 15 fire stations in the city, operated by the Telangana State Disaster and Fire Response Department. The government-owned India Post has five head post offices and many sub-post offices in Hyderabad, which are complemented by private courier services.

How long is the pipeline from the Nagarjuna Sagar Dam which the HMWSSB operates?
Answer: 116-kilometre-long (72 mi)

Problem: In 2002, Chinese geologist Chen Xuezhong published a Seismic Risk Analysis study in which he came to the conclusion that beginning with 2003, attention should be paid to the possibility of an earthquake with a magnitude of over 7.0 occurring in Sichuan region. He based his study on statistical correlation. That Sichuan is a seismically active area has been discussed for years prior to the quake, though few studies point to a specific date and time.
In what year did Chen Xuezhong publish an earthquake study?
The answer is the following: 2002

The USAF's KC-135 and KC-10 aerial refueling aircraft are based on civilian jets. The USAF aircraft are equipped primarily for providing the fuel via a tail-mounted refueling boom, and can be equipped with "probe and drogue" refueling systems. Air-to-air refueling is extensively used in large-scale operations and also used in normal operations; fighters, bombers, and cargo aircraft rely heavily on the lesser-known "tanker" aircraft. This makes these aircraft an essential part of the Air Force's global mobility and the U.S. force projection. The KC-46A Pegasus is undergoing testing and is projected to be delivered to USAF units starting in 2017.
What kind of aircraft is the USAF's KC-135?
aerial refueling aircraft

Input: Law of the United States
Early on, American courts, even after the Revolution, often did cite contemporary English cases. This was because appellate decisions from many American courts were not regularly reported until the mid-19th century; lawyers and judges, as creatures of habit, used English legal materials to fill the gap. But citations to English decisions gradually disappeared during the 19th century as American courts developed their own principles to resolve the legal problems of the American people. The number of published volumes of American reports soared from eighteen in 1810 to over 8,000 by 1910. By 1879 one of the delegates to the California constitutional convention was already complaining: "Now, when we require them to state the reasons for a decision, we do not mean they shall write a hundred pages of detail. We [do] not mean that they shall include the small cases, and impose on the country all this fine judicial literature, for the Lord knows we have got enough of that already."

What did the lawmakers think of the increase in reports?
Output: By 1879 one of the delegates to the California constitutional convention was already complaining

Problem: Please answer a question about the following article about Qing dynasty:
In 1884, pro-Japanese Koreans in Seoul led the Gapsin Coup. Tensions between China and Japan rose after China intervened to suppress the uprising. Japanese Prime Minister Ito Hirobumi and Li Hongzhang signed the Convention of Tientsin, an agreement to withdraw troops simultaneously, but the First Sino-Japanese War of 1895 was a military humiliation. The Treaty of Shimonoseki recognized Korean independence and ceded Taiwan and the Pescadores to Japan. The terms might have been harsher, but when Japanese citizen attacked and wounded Li Hongzhang, an international outcry shamed the Japanese into revising them. The original agreement stipulated the cession of Liaodong Peninsula to Japan, but Russia, with its own designs on the territory, along with Germany and France, in what was known as the Triple Intervention, successfully put pressure on the Japanese to abandon the peninsula.
Who signed the Convention of Tientsin?
A:
Ito Hirobumi and Li Hongzhang
