Problem: History of science:

The scientific revolution is a convenient boundary between ancient thought and classical physics. Nicolaus Copernicus revived the heliocentric model of the solar system described by Aristarchus of Samos. This was followed by the first known model of planetary motion given by Johannes Kepler in the early 17th century, which proposed that the planets follow elliptical orbits, with the Sun at one focus of the ellipse. Galileo ("Father of Modern Physics") also made use of experiments to validate physical theories, a key element of the scientific method.

Which movement is considered to be a dividing line between ancient thought and classical physics?
---
A: The scientific revolution

Problem: Bell and his partners, Hubbard and Sanders, offered to sell the patent outright to Western Union for $100,000. The president of Western Union balked, countering that the telephone was nothing but a toy. Two years later, he told colleagues that if he could get the patent for $25 million he would consider it a bargain. By then, the Bell company no longer wanted to sell the patent. Bell's investors would become millionaires, while he fared well from residuals and at one point had assets of nearly one million dollars.
What did the President think the telephone was, such that he refused to buy the patent?
---
Answer: a toy

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the 12th and 13th centuries, Europe produced economic growth and innovations in methods of production. Major technological advances included the invention of the windmill, the first mechanical clocks, the manufacture of distilled spirits, and the use of the astrolabe. Concave spectacles were invented around 1286 by an unknown Italian artisan, probably working in or near Pisa.
What was invented in approximately 1286?
A: Concave spectacles

Context and question: A glacier (US /ler/ or UK /lsi/) is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.
What other kinds of ice are thicker than glaciers?
Answer: unanswerable

Question: Though human activities have allowed the expansion of a few species, such as the barn swallow and European starling, they have caused population decreases or extinction in many other species. Over a hundred bird species have gone extinct in historical times, although the most dramatic human-caused avian extinctions, eradicating an estimated 7501800 species, occurred during the human colonisation of Melanesian, Polynesian, and Micronesian islands. Many bird populations are declining worldwide, with 1,227 species listed as threatened by BirdLife International and the IUCN in 2009.
Is there an answer to this question: When did the most dramatic human-caused avian extinctions occur?

Answer: during the human colonisation of Melanesian, Polynesian, and Micronesian islands

Question: Despite being an original story, Spectre draws on Ian Fleming's source material, most notably in the character of Franz Oberhauser, played by Christoph Waltz. Oberhauser shares his name with Hannes Oberhauser, a background character in the short story "Octopussy" from the Octopussy and The Living Daylights collection, and who is named in the film as having been a temporary legal guardian of a young Bond in 1983. Similarly, Charmian Bond is shown to have been his full-time guardian, observing the back story established by Fleming. With the acquisition of the rights to Spectre and its associated characters, screenwriters Neal Purvis and Robert Wade revealed that the film would provide a minor retcon to the continuity of the previous films, with the Quantum organisation alluded to in Casino Royale and introduced in Quantum of Solace reimagined as a division within Spectre rather than an independent organisation.
Is there an answer to this question: Which group in previous Bond films was changed to be a part of Spectre instead of its own entity?

Answer:
Quantum
