Thomas Hobbes was an early modern philosopher who put forth the idea of a "social contract" -- that governments are formed by the will of the people. This was different than previous views which held that governments (kings) got their authority directly from God.
Hobbes published a famous work called<em> Leviathan</em> in 1651. The title "Leviathan" comes from a biblical word for a great and mighty beast. Hobbes believed government is formed by people for the sake of their personal security and stability in society. In Hobbes' view, once the people put a king (or other leader in power), then that leader needs to have supreme power (like a great and mighty beast). Hobbes' view of the natural state of human beings without a government held that people are too divided and too volatile as individuals -- everyone looking out for his own interests. So for security and stability, authority and the power of the law needs to be in the hands of a powerful ruler like a king or queen. And so people willingly enter a social contract in which they live under a government that provides stability and security for society.
Probably the most famous set of lines from Hobbes' Leviathan book describes what he saw as the natural state of human affairs without government -- one in which every individual had freedom, but that meant it was a situation of "war of all against all," or we might say, every man for himself. Hobbes wrote:
-
<em>In such condition, there is no place for industry; because the fruit thereof is uncertain: and consequently no culture of the earth; no navigation, nor use of the commodities that may be imported by sea; no commodious building; no instruments of moving, and removing, such things as require much force; no knowledge of the face of the earth; no account of time; no arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short.

The correct answer is b.) All three developed progressively more accurate models of our solar system.
Indeed, Copernicus proposed the heliocentric model, placing the Sun as the center of the universe and not Earth, in the 15th century. Kepler discovered the three scientific laws of planetary orbit around the Sun in the 17th century. Newton created the laws of universal gravitation and motion in the 17th century as well, basing a good deal of his research on Kepler’s work.
Explanation:
Here's a (very) brief summary of the fall of the Aztec empire, after the arrival of Hernando Cortes until the fall of Tenochtitlán (read a biography of Hernan Cortez here):
1519 (March 4): The Spaniards land in what is now Veracruz. The natives greet him with gifts. A contingent from Tenochtitlán also arrives with gifts. Cortes showed force and demonstrated his canons, terrifying the messengers.
Cortes sinks all the ships except one small vessel, and moves to the city-state of Tlaxcala. Generally speaking they begin on friendly terms.
The Spanish went on to Cholula. It's unclear what happened, but in the end many people in the city were killed by the Spanish. Read more about Cholula here.
1519 (Nov 8): Cortes and army arrives at Tenochtitlán, and begin on good terms. However, Cortes takes charge and demands tribute and some Roman Catholic shrines to replace the Aztec gods.
Cortes returns to the coast to defeat a rival Spanish army. The remaining soldiers join him.
The Aztecs revolt, driving the Spanish from the city. Cuitláhuac becomes emperor.
The Spanish go to Tlaxcala and make an alliance with them.
Most Aztec cities are conquered, and a siege of Tenochtitlán begins.
1521 (13 August): The last Aztec emperor, Cuauhtémoc, surrenders to Cortes.
