Problem: Computer:

The bipolar transistor was invented in 1947. From 1955 onwards transistors replaced vacuum tubes in computer designs, giving rise to the "second generation" of computers. Compared to vacuum tubes, transistors have many advantages: they are smaller, and require less power than vacuum tubes, so give off less heat. Silicon junction transistors were much more reliable than vacuum tubes and had longer, indefinite, service life. Transistorized computers could contain tens of thousands of binary logic circuits in a relatively compact space.

When was the bipolar transistor created?
---
A: 1947.


Problem: The European powers continued to pursue diplomatic avenues. The representatives of the four neutral Great Powers—the United Kingdom, France, Austria and Prussia—met in Vienna, where they drafted a note that they hoped would be acceptable to both the Russians and the Ottomans. The peace terms arrived at by the four powers at the Vienna Conference were delivered to the Russians by the Austrian Foreign Minister Count Karl von Buol on 5 December 1853. The note met with the approval of Nicholas I; however, Abdülmecid I rejected the proposal, feeling that the document's poor phrasing left it open to many different interpretations. The United Kingdom, France, and Austria united in proposing amendments to mollify the Sultan, but the court of St. Petersburg ignored their suggestions.:143 The UK and France then set aside the idea of continuing negotiations, but Austria and Prussia did not believe that the rejection of the proposed amendments justified the abandonment of the diplomatic process.
Who approved the proposal given by Count Karl von Buol ?
---
Answer: Nicholas I

Vaccines rely on immune modulation or augmentation. Vaccination either excites or reinforces the immune competence of a host to ward off infection, leading to the activation of macrophages, the production of antibodies, inflammation, and other classic immune reactions. Antibacterial vaccines have been responsible for a drastic reduction in global bacterial diseases. Vaccines made from attenuated whole cells or lysates have been replaced largely by less reactogenic, cell-free vaccines consisting of purified components, including capsular polysaccharides and their conjugates, to protein carriers, as well as inactivated toxins (toxoids) and proteins.
What types of vaccines have been phased out?
A: Vaccines made from attenuated whole cells or lysates


Context and question: Cyborg anthropology originated as a sub-focus group within the American Anthropological Association's annual meeting in 1993. The sub-group was very closely related to STS and the Society for the Social Studies of Science. Donna Haraway's 1985 Cyborg Manifesto could be considered the founding document of cyborg anthropology by first exploring the philosophical and sociological ramifications of the term. Cyborg anthropology studies humankind and its relations with the technological systems it has built, specifically modern technological systems that have reflexively shaped notions of what it means to be human beings.
What does cyborg anthropology study about humankind and technological systems humans have built?
Answer: its relations


Question: Valleys and plains are found along the coastline and rivers. The north of the province lies just south of the Yangtze Delta, and consists of plains around the cities of Hangzhou, Jiaxing, and Huzhou, where the Grand Canal of China enters from the northern border to end at Hangzhou. Another relatively flat area is found along the Qu River around the cities of Quzhou and Jinhua. Major rivers include the Qiangtang and Ou Rivers. Most rivers carve out valleys in the highlands, with plenty of rapids and other features associated with such topography. Well-known lakes include the West Lake of Hangzhou and the South Lake of Jiaxing.
Is there an answer to this question: What is a minor river of the province in addition to the Qiangtang River?

Answer: unanswerable

Two Polish friends in Paris were also to play important roles in Chopin's life there. His fellow student at the Warsaw Conservatory, Julian Fontana, had originally tried unsuccessfully to establish himself in England; Albert Grzymała, who in Paris became a wealthy financier and society figure, often acted as Chopin's adviser and "gradually began to fill the role of elder brother in [his] life." Fontana was to become, in the words of Michałowski and Samson, Chopin's "general factotum and copyist".
Who was Frédéric's trusted adviser while in Paris?
A:
Albert Grzymała
