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 Roët, making her a direct descendant of Edward III.

question:
Question: Was Hirohito an adult when the San Francisco Peace Treaty was signed? Passage:The Allied occupation of Japan at the end of World War II was led by General Douglas MacArthur, the Supreme Commander of the Allied Powers, with support from the British Commonwealth. Unlike in the occupation of Germany, the Soviet Union was allowed little to no influence over Japan. This foreign presence marks the only time in Japan's history that it has been occupied by a foreign power. At MacArthur's insistence, Emperor Hirohito remained on the imperial throne. The wartime cabinet was replaced with a cabinet acceptable to the Allies and committed to implementing the terms of the Potsdam Declaration, which among other things called for the country to become a parliamentary democracy. Under MacArthur's guidance, the Japanese government introduced sweeping social reforms and implemented economic reforms that recalled American "New Deal" priorities of the 1930s under President Roosevelt. The Japanese constitution was comprehensively overhauled and the Emperor's theoretically-vast powers, which for many centuries had been constrained by conventions that had evolved over time, became strictly limited by law. The occupation, codenamed Operation Blacklist, was ended by the San Francisco Peace Treaty, signed on September 8, 1951, and effective from April 28, 1952, after which Japan's sovereigntywith the exception, until 1972, of the Ryukyu Islands was fully restored.

question:
Question: Are there any colleges in the suburb where Terri grew up? Passage:Gibbs was born in Miami, Florida, but raised in the Augusta, Georgia, suburb of Grovetown. Although born with eyesight, she lost it as a newborn due to an incubator accident. Despite her blindness, she learned to play piano at age three. As a child, she sang in the church choir and at talent contests, and at age seventeen, she opened for Bill Anderson. Her parents wanted her to be treated no differently from sighted people and she was sent to public school, graduating from Butler High School in Augusta in 1972. She performed in and around the Augusta area and eventually, she met Chet Atkins, who advised her to move to Nashville, Tennessee, to pursue a country music career, which she did at age eighteen. After failing to find a record deal, she returned to Miami and joined a band called Sound Dimension. She continued to perform locally, later forming a band called the Terri Gibbs Trio, which performed at a Steak and Ale in Augusta, Georgia. Gibbs then sent a demo tape to record producer Ed Penney of MCA Records, signing to the label in 1980. Penney was a former Boston disc jockey and a long-time songwriter. He liked her voice on her demo, but felt she needed stronger material. He co-wrote "Somebody's Knockin'" for her and also produced the song.
