the entire Western Hemisphere would come under the domination of European nations, leading to profound changes to its landscape, population, and plant and animal life. In the nineteenth century alone over 50 million people left Europe for the Americas. The post-1492 era is known as the period of the Columbian Exchange. The potato, the pineapple, the turkey, dahlias, sunflowers, magnolias, maize, chilies, and chocolate went East across the Atlantic Ocean. Smallpox and measles but also the horse and the gun traveled West.The European and Asian lifestyle included a long history of sharing close quarters with domesticated animals such as cows, pigs, sheep, goats, horses, and various domesticated fowl, which had resulted in epidemic diseases unknown in the Americas.The first conquests were made by the Spanish and the Portuguese. In the 1494 Treaty of Tordesillas, ratified by the Pope, these two kingdoms divided the entire non-European world between themselves, with a line drawn through South America.
Answer:
D. No, since some theories better account for more important data than do others.
Explanation:
While it is true that total objectivity is impossible, and no theory can fully explain a phenomenon, some theories are better than others at explaining things (mostly because they are built on previous theories).
For example, Einstein's General Relativity is better at explaining the Universe than Newton's laws of general motion, or Copernicus' heliocentric view of the Universe, even while the three theories are an improvement over the Ptolemaic geocentric cosmology that dominated Western thought for millenia.
And while Einstein's theories are not perfect, adhering to Newton's or Copernicus' theory instead would be unscientific.
