Which theory holds that language shapes our thoughts and perceptions to such an extent that people who speak languages that lack
Bas_tet [7]

Answer:

c. Linguistic determinism hypothesis.

Explanation:

The linguistic determinism hypothesis is also known as the Sapir-Whorf hypothesis. According to this theory, the language we speak determines our thought processes - such as memorization, categorization, and perception - and influences our social reality. Therefore, people who grow up speaking different mother tongues may have a hard time expressing their ideas in other languages. Their ideas and perceptions of the world are connected to the language they speak.

The Sapir-Whorf theory is used in the movie "Arrival", in which a linguist's cognitive processes are deeply enhanced by learning and immersing in an alien language.

Why did native American have a high death rate from European disease ​
Greeley [361]

Answer:

There were an estimated 18 million Native Americans living north of Mexico at the beginning of the European invasion. Prior to the arrival of the Europeans, American Indians were remarkably free of serious diseases. People did not often die from diseases. As the European explorers and colonists began to arrive, this changed and the consequences were disastrous for Native American people. The death tolls from the newly introduced European diseases often reached 80-90 percent. Entire groups of people vanished before the tidal wave of disease.  

Explanation:

The diseases brought to this continent by the Europeans included bubonic plague, chicken pox, pneumonic plague, cholera, diphtheria, influenza, measles, scarlet fever, smallpox, typhus, tuberculosis, and whooping cough. The diseases introduced in the Americas by the Europeans were crowd diseases: that is, individuals who have once contracted the disease and survived become immune to the disease. In a small population, the disease will become extinct. Measles, for instance, requires a population of about 300,000 to survive. If the population size drops below this threshold, the virus can cause illness and death, but after one epidemic, the virus itself dies out.

Another important factor in the European diseases was the presence of domesticated animals. The source of many of the infections was the domesticated animals which lived in close proximity with the humans.

Overall, hundreds of thousands of Indians died of European diseases during the first two centuries following contact. In terms of death tolls, smallpox killed the greatest number of Indians, followed by measles, influenza, and bubonic plague.

Ibn khaldun, a muslim historian was one of the first to study
AnnZ [28]

His family's high rank enabled Ibn Khaldun to study with the best teachers in Maghreb. He received a classical Islamic education, studying the Quran, which he memorized by heart, Arabic linguistics; the basis for understanding the Qur'an, hadith, sharia (law) and fiqh (jurisprudence). He received certification (ijazah) for all of those subjects.[18] The mathematician and philosopher Al-Abili of Tlemcen introduced him to mathematics, logic and philosophy, and he studied especially the works of Averroes, Avicenna, Razi and Tusi. At the age of 17, Ibn Khaldūn lost both his parents to the Black Death, an intercontinental epidemic of the plague that hit Tunis in 1348–1349.[19]

Following family tradition, he strove for a political career. In the face of a tumultuous political situation in North Africa, that required a high degree of skill in developing and dropping alliances prudently to avoid falling with the short-lived regimes of the time.[20][citation needed] Ibn Khaldūn's autobiography is the story of an adventure, in which he spends time in prison, reaches the highest offices and falls again into exile.[citation needed]
