Question: Question: How many wives did Katherine's maternal grandfather have? Passage:Lady Katherine Neville was born in 1442, one of the ten children and the fifth eldest daughter of Richard Neville, 5th Earl of Salisbury and Alice Montacute, suo jure 5th Countess of Salisbury. Her mother was the only child and heiress of Thomas Montacute, 4th Earl of Salisbury by his first wife Lady Eleanor Holland. Katherine's eldest brother was Richard Neville, 16th Earl of Warwick, 6th Earl of Salisbury, also known as "Warwick the Kingmaker". He was the most important and influential peer in the realm, and one of the principal protagonists in the Wars of the Roses. Her aunt, Cecily Neville, Duchess of York, mother of future kings and Katherine's first cousins, Edward IV and Richard III, was another key figure in the dynastic civil wars that dominated most of the latter half of 15th century England. Her niece, Anne Neville (youngest daughter of the "Kingmaker") would become Queen of England as the consort of Richard III; Katherine's sister Alice, Baroness FitzHugh, and her other niece, Elizabeth FitzHugh, were personally selected as Anne's chief ladies-in-waiting. Her paternal grandparents were Ralph Neville, 1st Earl of Westmorland and Joan Beaufort, Countess of Westmoreland, a daughter of John of Gaunt by his third wife, Katherine de Roet, making her a direct descendant of Edward III.

Question: Question: Did the trade affect the Aleut people negatively? Passage:The maritime fur trade brought the Pacific Northwest coast into a vast, new international trade network, centered on the north Pacific Ocean, global in scope, and based on capitalism, but not, for the most part, on colonialism. A triangular trade network emerged linking the Pacific Northwest coast, China, the Hawaiian Islands (only recently discovered by the Western world), Britain, and the United States (especially New England). The trade had a major effect on the indigenous people of the Pacific Northwest coast, especially the Aleut, Sugpiaq, Tlingit, Haida, Nuu-chah-nulth, and Chinook peoples. A rapid increase of wealth occurred among the Northwest Coast natives, along with increased warfare, potlatching, slaving, and depopulation due to epidemic disease. However, the indigenous culture was not overwhelmed by rapid change, but actually flourished. For instance, the importance of totems and traditional nobility crests increased, and the Chinook Jargon, which remains a distinctive aspect of Pacific Northwest culture, was developed during this era. Native Hawaiian society was similarly affected by the sudden influx of Western wealth and technology, as well as epidemic diseases. The trade's effect on China and Europe was minimal, but for New England, the maritime fur trade and the significant profits it made helped revitalize the region, contributing to its transformation from an agrarian to an industrial society. The wealth generated by the maritime fur trade was invested in industrial development, especially textile manufacturing.

Question: Question: What landmarks are in Gordon's hometown? Passage:A Seattle native, Gordon exhibited an early interest in theoretical physics, especially quantum mechanics and the theory of relativity. His childhood heroes were Albert Einstein, Stephen Hawking, and Richard Feynman. After observing a series of teleportation experiments conducted by the Institute for Experimental Physics at the University of Innsbruck, the transmission of matter became Gordon's obsession. Gordon has no known dependents. He graduated from the Massachusetts Institute of Technology with a Ph.D. degree in Theoretical Physics. His doctoral thesis on the teleportation of matter through extremely dense elements was titled Observation of Einstein-Podolsky-Rosen Entanglement on Supraquantum Structures by Induction Through Nonlinear Transuranic Crystal of Extremely Long Wavelength (ELW) Pulse from Mode-Locked Source Array. Gordon's research into science eventually led him to accept a job offer by the Black Mesa Research Facility, and begin working on a top-secret research project headed by his mentor at MIT, Dr. Isaac Kleiner. He takes up residence at Black Mesa, conducting nuclear and subatomic research in its Anomalous Materials department. Despite his education as a theoretical physicist, the work Freeman is involved with at Black Mesa is of a more experimental nature.
