Problem: Please answer a question about the following article about Glacier:
Ogives are alternating wave crests and valleys that appear as dark and light bands of ice on glacier surfaces. They are linked to seasonal motion of glaciers; the width of one dark and one light band generally equals the annual movement of the glacier. Ogives are formed when ice from an icefall is severely broken up, increasing ablation surface area during summer. This creates a swale and space for snow accumulation in the winter, which in turn creates a ridge. Sometimes ogives consist only of undulations or color bands and are described as wave ogives or band ogives.
How are ogives formed?
A: when ice from an icefall is severely broken up, increasing ablation surface area during summer
Problem: Please answer a question about the following article about Communication:
The broad field of animal communication encompasses most of the issues in ethology. Animal communication can be defined as any behavior of one animal that affects the current or future behavior of another animal. The study of animal communication, called zoo semiotics (distinguishable from anthroposemiotics, the study of human communication) has played an important part in the development of ethology, sociobiology, and the study of animal cognition. Animal communication, and indeed the understanding of the animal world in general, is a rapidly growing field, and even in the 21st century so far, a great share of prior understanding related to diverse fields such as personal symbolic name use, animal emotions, animal culture and learning, and even sexual conduct, long thought to be well understood, has been revolutionized. A special field of animal communication has been investigated in more detail such as vibrational communication.
What is the study of human communication called?
A: anthroposemiotics
Problem: Please answer a question about the following article about Napoleon:
Napoleon continued to entertain a grand scheme to establish a French presence in the Middle East in order to put pressure on Britain and Russia, and perhaps form an alliance with the Ottoman Empire. In February 1806, Ottoman Emperor Selim III finally recognized Napoleon as Emperor. He also opted for an alliance with France, calling France "our sincere and natural ally." That decision brought the Ottoman Empire into a losing war against Russia and Britain. A Franco-Persian alliance was also formed between Napoleon and the Persian Empire of Fath-Ali Shah Qajar. It collapsed in 1807, when France and Russia themselves formed an unexpected alliance. In the end, Napoleon had made no effective alliances in the Middle East.
In what year did Napoleon's Franco-Persian alliance end?
A: 1807
Problem: Please answer a question about the following article about Vacuum:
Historically, there has been much dispute over whether such a thing as a vacuum can exist. Ancient Greek philosophers debated the existence of a vacuum, or void, in the context of atomism, which posited void and atom as the fundamental explanatory elements of physics. Following Plato, even the abstract concept of a featureless void faced considerable skepticism: it could not be apprehended by the senses, it could not, itself, provide additional explanatory power beyond the physical volume with which it was commensurate and, by definition, it was quite literally nothing at all, which cannot rightly be said to exist. Aristotle believed that no void could occur naturally, because the denser surrounding material continuum would immediately fill any incipient rarity that might give rise to a void.
What did Aristotle believe about a void?
A:
no void could occur naturally,
