Avoid answers that are incorrect or provides incomplete justification for the question.

[EX Q]: Passage: Other cities with a concentration of secular Gothic include Bruges and Siena. Most surviving small secular buildings are relatively plain and straightforward; most windows are flat-topped with mullions, with pointed arches and vaulted ceilings often only found at a few focal points. The country-houses of the nobility were slow to abandon the appearance of being a castle, even in parts of Europe, like England, where defence had ceased to be a real concern. The living and working parts of many monastic buildings survive, for example at Mont Saint-Michel. Question: What style are most windows on secular Gothic structures?
[EX A]: flat-topped with mullions

[EX Q]: Passage: A series of experiments performed from the late 1800s to the early 1900s revealed that diabetes is caused by the absence of a substance normally produced by the pancreas. In 1869, Oskar Minkowski and Joseph von Mering found that diabetes could be induced in dogs by surgical removal of the pancreas. In 1921, Canadian professor Frederick Banting and his student Charles Best repeated this study, and found that injections of pancreatic extract reversed the symptoms produced by pancreas removal. Soon, the extract was demonstrated to work in people, but development of insulin therapy as a routine medical procedure was delayed by difficulties in producing the material in sufficient quantity and with reproducible purity. The researchers sought assistance from industrial collaborators at Eli Lilly and Co. based on the company's experience with large scale purification of biological materials. Chemist George Walden of Eli Lilly and Company found that careful adjustment of the pH of the extract allowed a relatively pure grade of insulin to be produced. Under pressure from Toronto University and a potential patent challenge by academic scientists who had independently developed a similar purification method, an agreement was reached for non-exclusive production of insulin by multiple companies. Prior to the discovery and widespread availability of insulin therapy the life expectancy of diabetics was only a few months. Question: Who discovered that pancreatic extract reversed symptoms of pancreas removal?
[EX A]: Frederick Banting and his student Charles Best

[EX Q]: Passage: After Kerry's third qualifying wound, he was entitled per Navy regulations to reassignment away from combat duties. Kerry's preferred choice for reassignment was as a military aide in Boston, New York or Washington, D.C. On April 11, 1969, he reported to the Brooklyn-based Atlantic Military Sea Transportation Service, where he would remain on active duty for the following year as a personal aide to an officer, Rear Admiral Walter Schlech. On January 1, 1970 Kerry was temporarily promoted to full Lieutenant. Kerry had agreed to an extension of his active duty obligation from December 1969 to August 1970 in order to perform Swift Boat duty. John Kerry was on active duty in the United States Navy from August 1966 until January 1970. He continued to serve in the Naval Reserve until February 1978. Question: Where was Kerry reassigned in April 1969?
[EX A]:
the Brooklyn-based Atlantic Military Sea Transportation Service
