Input: Consider Input: Question: Was Willemstad successfully defended against the French in 1793? Passage:By the 1790s Braak was in the Caribbean, and was present at the defence against the French of Willemstad, part of the Dutch colony at Curaçao, in 1793. By late 1794 she was ordered to escort a convoy of East Indiamen to Batavia in the Netherlands East Indies. En route she called at the English port of Falmouth, unaware that the French had since invaded the Netherlands and proclaimed the Batavian Republic as a client state, compelling the Dutch to declare war on the British. On the arrival of the convoy at falmouth, the Royal Navy seized the 26 merchantmen and six warships of the convoy, including De Braak. A boarding party from the sloop-of-war took over De Braak. Forty-six Royal Navy vessels that were at Plymouth shared in the prize money.

Input: Consider Input: Question: Who was younger the year Gorelick earned her M.A., Raphael Soyer or Moses Soyer? Passage:Born Shirley Fishman in Brooklyn, New York, she attended Abraham Lincoln High School. Her teacher, Leon Friend, arranged for guest lectures by commercial and fine artists. Shirley Fishman had the opportunity to study with three of them: Chaim Gross, Moses Soyer, and Raphael Soyer. Gross influenced her early sculptural work, which features squat figures with thick limbs. While attending Brooklyn College, where she earned her B.A. in 1944, she met Leonard Gorelick (1922–2011), a fellow student. They married in 1944 and shared an enthusiasm for art and culture. Leonard Gorelick was an orthodontist and later a collector of cylinder seals. He combined his interests by investigating the authenticity of cylinder seals through the use of dental technology, especially electronmicroscopy. Shirley Gorelick earned an M.A. at Teachers College, Columbia University in 1947. That year, she studied for several weeks with Hans Hofmann in Provincetown. For a short time in the late 1950s, she was a student of the painter Betty Holliday and, in the early 1960s, learned printmaking in the Long Island studio of Ruth Leaf.
