Example Input: Question: What was the final score in the loss to the Houston Rockets on March 30? Passage:On December 8, 2017, the Phoenix Suns signed House to a two-way contract with the team. Throughout the rest of the season, House would split his playing time there between Phoenix and their NBA G League squad, the Northern Arizona Suns. House would make his debut with the team a day later, scoring two points and recording a single rebound in 11 minutes of play in a close loss against the San Antonio Spurs. On December 16, House would score a season-high 8 points in 15 minutes of playing time in a 108106 win over the Minnesota Timberwolves. House was later assigned to the Northern Arizona Suns affiliate alongside Davon Reed on December 28, mainly for healing purposes. House then returned to action on January 5, 2018, recording what was at the time a new season-high 9 points in a loss against the San Antonio Spurs. On February 23, his two-way contract expired, meaning he couldn't be allowed to play for Phoenix again until after the NBA G League's first season under its rebranded name concluded. Once that happened, he was allowed to return to Phoenix for the rest of the season. On March 30, House recorded a career-high 8 rebounds in a heartbreaking, buzzer-beating loss against the Houston Rockets. On April 1, House would record a new season-high with 16 points scored alongside 6 rebounds and 3 assists in a 117107 loss against the Golden State Warriors. Two days later, House recorded 14 points, 6 rebounds, and a career-high 5 assists in a 9794 win against the Sacramento Kings. On April 6, House would put up his first start in the NBA against the New Orleans Pelicans. Two days later, House would record career-highs of 22 points and 8 rebounds in a 117100 loss to the Golden State Warriors.

Example Input: 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, NiemannPick disease, Fabry disease and the specific metabolic abnormality in TaySachs 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.
