[Q]: Passage: The European colonization of the Americas forever changed the lives and cultures of the peoples of the continents. Although the exact pre-contact population of the Americas is unknown, scholars estimate that Native American populations diminished by between 80 and 90% within the first centuries of contact with Europeans. The leading cause was disease. The continent was ravaged by epidemics of diseases such as smallpox, measles, and cholera, which were brought from Europe by the early explorers and spread quickly into new areas even before later explorers and colonists reached them. Native Americans suffered high mortality rates due to their lack of prior exposure to these diseases. The loss of lives was exacerbated by conflict between colonists and indigenous people. Colonists also frequently perpetrated massacres on the indigenous groups and enslaved them. According to the U.S. Bureau of the Census (1894), the North American Indian Wars of the 19th century cost the lives of about 19,000 whites and 30,000 Native Americans. Question: What did the European colonization forever change?
[A]: lives and cultures of the peoples of the continents


[Q]: Passage: The Vedānta school built upon the teachings of the Upanishads and Brahma Sutras from the first millennium BCE and is the most developed and well-known of the Hindu schools. The epistemology of the Vedantins included, depending on the sub-school, five or six methods as proper and reliable means of gaining any form of knowledge: pratyakṣa (perception), anumāṇa (inference), upamāṇa (comparison and analogy), arthāpatti (postulation, derivation from circumstances), anupalabdi (non-perception, negative/cognitive proof) and śabda (word, testimony of past or present reliable experts). Each of these have been further categorized in terms of conditionality, completeness, confidence and possibility of error, by each sub-school of Vedanta. Question: Which is the most developed and well known of the Hindu schools?
[A]: Vedānta


[Q]: Passage: Sensory memory holds sensory information less than one second after an item is perceived. The ability to look at an item and remember what it looked like with just a split second of observation, or memorization, is the example of sensory memory. It is out of cognitive control and is an automatic response. With very short presentations, participants often report that they seem to "see" more than they can actually report. The first experiments exploring this form of sensory memory were conducted by George Sperling (1963) using the "partial report paradigm". Subjects were presented with a grid of 12 letters, arranged into three rows of four. After a brief presentation, subjects were then played either a high, medium or low tone, cuing them which of the rows to report. Based on these partial report experiments,Sperling was able to show that the capacity of sensory memory was approximately 12 items, but that it degraded very quickly (within a few hundred milliseconds). Because this form of memory degrades so quickly, participants would see the display but be unable to report all of the items (12 in the "whole report" procedure) before they decayed. This type of memory cannot be prolonged via rehearsal. Question: Who did the first studies on exploring a new idea of sensory memory?
[A]:
George Sperling
