Assuming that the asterisks come before (not after) the chosen Your first answer is correct, the last option (the Aztecs and the Incas). The Olmec civilization is one of the oldest Pre-Columbian civilizations, and ended well before the arrival of Europeans.

The Aztecs were conquered by a Spaniard named Cortes and his troops, and the Incas were conquered by a Spaniard named Pizarro and his troops. Your second answer is incorrect. The Columbian Exchange wasn't only the trade of goods (including crops and animals), but also a diffusion of culture and disease (which played a large role in decimating indigenous populations who had no tolerance for these diseases). Your third answer is correct. The Protestant Reformation was a response to the abuse and corruption of the Catholic Church.

Your fourth answer is incorrect. The correct answer is the second option, raw materials and a large workforce. An Industrial Revolution is when a country begins to produce a lot of goods and services in a small amount of time. To do so, it's imperative to have 3 things: land, labor, and capital. The second option has two of these requirements (raw materials come from land and the workforce makes up the labor). The larger the workforce and the more raw materials available, the more goods that can be produced.
