In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Question: In which state did Don Cardwell no-hit the St. Louis Cardinals 4-0 in the second game of a doubleheader? Passage:Cardwell was traded to the Cubs on May 13, 1960, for Tony Taylor. Two days later, he no-hit the St. Louis Cardinals 4–0 in the second game of a doubleheader at Wrigley Field—the first no-hitter ever thrown by a pitcher in his first start with a new team. The lone baserunner for the Cardinals was by a walk from Cardwell to Alex Grammas with one out in the first inning; Cardwell then retired the next 26 batters. Two ninth-inning catches enabled Cardwell to secure the no-hitter: the first catch by Cubs right fielder George Altman on a Carl Sawatski line drive for the first out of the inning, and the second catch by Cubs left fielder Walt "Moose" Moryn on Joe Cunningham's sinking line drive to end the game, Moryn catching the ball just inches off the ground. Cardwell finished the season 9–16 and the Cubs 60–94 despite his no-hitter. Cardwell also showed his hitting ability in 1960, getting 16 hits including five home runs in 77 at bats for a .208 batting average.

Question: In what year was George Canning Prime Minister? Passage:Garvagh was the son of Paul Canning and the grandson of Stratford Canning of Garvagh in County Londonderry. Prime Minister George Canning and the diplomat Stratford Canning, 1st Viscount Stratford de Redcliffe, were his first cousins. He was elected to the House of Commons for Sligo Borough in 1806, a seat he held until 1812, and then represented Petersfield from 1812 to 1820. On 1 February 1810 he was elected a Fellow of the Royal Society and on 28 October 1818 he was raised to the Peerage of Ireland as Baron Garvagh, of Garvagh in the County of Londonderry. Lord Garvagh later served as Lord Lieutenant of County Londonderry between 1831 and 1840. He died while staying at a hotel in Châlons-sur-Marne (now renamed Châlons-en-Champagne) in August 1840, aged 61, and was succeeded in the barony by his son Charles Henry Spencer George Canning.

Question: In what 2 states did Roscoe Brady receive university level education? Passage:He attended the Pennsylvania State University and obtained his M.D. degree from Harvard Medical School in 1947. He interned at the Hospital of the University of Pennsylvania. From 1948 to 1952 he was a post-doctoral fellow in the Department of Physiological Chemistry at the University of Pennsylvania School of Medicine and fellow in clinical medicine in the Department of Medicine. In collaboration with Samuel Gurin at the University of Pennsylvania, Brady discovered the enzyme system for the biosynthesis of long chain fatty acids, and later discovered the role of malonate coenzyme A in this process. After two and one-half years on active duty in the U.S. Naval Medical Corps, he joined the National Institutes of Health in 1954. He was Chief of the Developmental and Metabolic Neurology Branch in the National Institute of Neurological Disorders and Stroke from 1972 to 2006. Dr. Brady and his colleagues identified the enzymatic defects in Gaucher's disease, Niemann–Pick disease, Fabry disease and the specific metabolic abnormality in Tay–Sachs disease. He and his associates developed diagnostic, carrier detection, prenatal tests for these conditions, and effective enzyme replacement therapy for patients with Gaucher disease and Fabry disease. These were the first-ever enzyme replacement therapy (ERT) treatments for lysosomal diseases, and directly led to great advances in the development of enzyme replacement therapies for some of the other lysosomal diseases, by many different researchers who were inspired by Dr. Brady. (An international research and development effort for new ERT for several devastating lysosomal diseases continues today at an intense pace, and numerous ERT clinical trials are underway.) Late in his life, Dr. Brady was investigating substrate depletion, molecular chaperone therapy, and gene therapy for patients with metabolic storage disorders.
