QUES: The Continental Army was created on 14 June 1775 by the Continental Congress as a unified army for the colonies to fight Great Britain, with George Washington appointed as its commander. The army was initially led by men who had served in the British Army or colonial militias and who brought much of British military heritage with them. As the Revolutionary War progressed, French aid, resources, and military thinking influenced the new army. A number of European soldiers came on their own to help, such as Friedrich Wilhelm von Steuben, who taught the army Prussian tactics and organizational skills.
What European did Friedrich Wilhelm von Steuben come from?

Although Dominic and the early brethren had instituted female Dominican houses at Prouille and other places by 1227, some of the brethren of the order had misgivings about the necessity of female religious establishments in an order whose major purpose was preaching, a duty in which women could not traditionally engage. In spite of these doubts, women's houses dotted the countryside throughout Europe. There were seventy-four Dominican female houses in Germany, forty-two in Italy, nine in France, eight in Spain, six in Bohemia, three in Hungary, and three in Poland. Many of the German religious houses that lodged women had been home to communities of women, such as Beguines, that became Dominican once they were taught by the traveling preachers and put under the jurisdiction of the Dominican authoritative structure. A number of these houses became centers of study and mystical spirituality in the 14th century. There were one hundred and fifty-seven nunneries in the order by 1358. In that year, the number lessened due to disasters like the Black Death.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where in England was one female Dominican house located?
Ah, so.. unanswerable

Question: Before the war, many observers believed the US and its allies could win but might suffer substantial casualties (certainly more than any conflict since Vietnam), and that the tank battles across the harsh desert might rival those of North Africa during World War II. After nearly 50 years of proxy wars, and constant fears of another war in Europe between NATO and the Warsaw Pact, some thought the Persian Gulf War might finally answer the question of which military philosophy would have reigned supreme. Iraqi forces were battle-hardened after 8 years of war with Iran, and they were well equipped with late model Soviet tanks and jet fighters, but the antiaircraft weapons were crippled; in comparison, the US had no large-scale combat experience since its withdrawal from Vietnam nearly 20 years earlier, and major changes in US doctrine, equipment and technology since then had never been tested under fire.
Try to answer this question if possible: Prior to the Persian Gulf War, where and when was the last major American military conflict?
Answer: Vietnam nearly 20 years earlier
