Problem: Please answer a question about the following article about On the Origin of Species:
He notes that both A. P. de Candolle and Charles Lyell had stated that all organisms are exposed to severe competition. Darwin emphasizes that he used the phrase "struggle for existence" in "a large and metaphorical sense, including dependence of one being on another"; he gives examples ranging from plants struggling against drought to plants competing for birds to eat their fruit and disseminate their seeds. He describes the struggle resulting from population growth: "It is the doctrine of Malthus applied with manifold force to the whole animal and vegetable kingdoms." He discusses checks to such increase including complex ecological interdependencies, and notes that competition is most severe between closely related forms "which fill nearly the same place in the economy of nature".
What was Charles Lyell's perception of what organisms are exposed to in their struggle for survival?
A: all organisms are exposed to severe competition
Problem: Please answer a question about the following article about Modern history:
Under Peter I (the Great), Russia was proclaimed an Empire in 1721 and became recognized as a world power. Ruling from 1682 to 1725, Peter defeated Sweden in the Great Northern War, forcing it to cede West Karelia and Ingria (two regions lost by Russia in the Time of Troubles), as well as Estland and Livland, securing Russia's access to the sea and sea trade. On the Baltic Sea Peter founded a new capital called Saint Petersburg, later known as Russia's Window to Europe. Peter the Great's reforms brought considerable Western European cultural influences to Russia. Catherine II (the Great), who ruled in 1762–96, extended Russian political control over the Polish-Lithuanian Commonwealth and incorporated most of its territories into Russia during the Partitions of Poland, pushing the Russian frontier westward into Central Europe. In the south, after successful Russo-Turkish Wars against the Ottoman Empire, Catherine advanced Russia's boundary to the Black Sea, defeating the Crimean khanate.
In what year was Russia declared an empire?
A: 1721
Problem: Please answer a question about the following article about Airport:
The majority of the world's airports are non-towered, with no air traffic control presence. However, at particularly busy airports, or airports with other special requirements, there is an air traffic control (ATC) system whereby controllers (usually ground-based) direct aircraft movements via radio or other communications links. This coordinated oversight facilitates safety and speed in complex operations where traffic moves in all three dimensions. Air traffic control responsibilities at airports are usually divided into at least two main areas: ground and tower, though a single controller may work both stations. The busiest airports also have clearance delivery, apron control, and other specialized ATC stations.
ATC responsibilities are usually divided into how many main areas?
A: two
Problem: Please answer a question about the following article about Indigenous peoples of the Americas:
About 5% of the Nicaraguan population are indigenous. The largest indigenous group in Nicaragua is the Miskito people. Their territory extended from Cape Camarón, Honduras, to Rio Grande, Nicaragua along the Mosquito Coast. There is a native Miskito language, but large groups speak Miskito Coast Creole, Spanish, Rama and other languages. The Creole English came about through frequent contact with the British who colonized the area. Many are Christians. Traditional Miskito society was highly structured with a defined political structure. There was a king, but he did not have total power. Instead, the power was split between himself, a governor, a general, and by the 1750s, an admiral. Historical information on kings is often obscured by the fact that many of the kings were semi-mythical. Another major group is the Mayangna (or Sumu) people, counting some 10,000 people.
What didn't the king have in Miskito society?
A:
total power
