In 1492, Granada was captured from the Moors, thereby completing the Reconquista. Portugal had during the 15th century – particularly under Henry the Navigator – gradually explored the coast of Africa, and in 1498, Vasco da Gama found the sea route to India. The Spanish monarchs met the Portuguese challenge by financing the expedition of Christopher Columbus to find a western sea route to India, leading to the discovery of the Americas in 1492.

Problem: Given the question: Extract the answer to the question from the following context. Question: what is pickford's first name Context: Slack (2003) compares three groups that conducted biological research at Yale during overlapping periods between 1910 and 1970. Yale proved important as a site for this research. The leaders of these groups were Ross Granville Harrison, Grace E. Pickford, and G. Evelyn Hutchinson, and their members included both graduate students and more experienced scientists. All produced innovative research, including the opening of new subfields in embryology, endocrinology, and ecology, respectively, over a long period of time. Harrison's group is shown to have been a classic research school; Pickford's and Hutchinson's were not. Pickford's group was successful in spite of her lack of departmental or institutional position or power. Hutchinson and his graduate and postgraduate students were extremely productive, but in diverse areas of ecology rather than one focused area of research or the use of one set of research tools. Hutchinson's example shows that new models for research groups are needed, especially for those that include extensive field research.

Grace


Problem: Given the question: Extract the answer to the question from the following context. Question: What had drinks that were served by girls? Context: In addition to the classical restaurants, Paris has several other kinds of traditional eating places. The café arrived in Paris in the 17th century, when the beverage was first brought from Turkey, and by the 18th century Parisian cafés were centres of the city's political and cultural life. The Cafe Procope on the Left Bank dates from this period. In the 20th century, the cafés of the Left Bank, especially Café de la Rotonde and Le Dôme Café in Montparnasse and Café de Flore and Les Deux Magots on Boulevard Saint Germain, all still in business, were important meeting places for painters, writers and philosophers. A bistro is a type of eating place loosely defined as a neighbourhood restaurant with a modest decor and prices and a regular clientele and a congenial atmosphere. Its name is said to have come in 1814 from the Russian soldiers who occupied the city; "bistro" means "quickly" in Russian, and they wanted their meals served rapidly so they could get back their encampment. Real bistros are increasingly rare in Paris, due to rising costs, competition from cheaper ethnic restaurants, and different eating habits of Parisian diners. A brasserie originally was a tavern located next to a brewery, which served beer and food at any hour. Beginning with the Paris Exposition of 1867; it became a popular kind of restaurant which featured beer and other beverages served by young women in the national costume associated with the beverage, particular German costumes for beer. Now brasseries, like cafés, serve food and drinks throughout the day.
