Detailed Instructions: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Problem:Passage: On the morning of April 21, 1914, warships of the United States Atlantic Fleet under the command of Rear Admiral Frank Friday Fletcher, began preparations for the seizure of the Veracruz waterfront. At 11:12 hrs, consul William Canada watched from the roof of the American Consulate as the first boatload of Marines left the auxiliary vessel USSPrairie. By 11:30, with whaleboats swung over the side, 502 U.S. Marines from the 2nd Advanced Base Regiment, 285 armed Navy sailors, known as "Bluejackets," from the battleship USSFlorida and a provisional battalion composed of the Marine detachments from Florida and her sister ship USSUtah also began landing operations. As the landing party moved toward pier 4, Veracruz's main wharf, a large crowd of Mexican and American citizens gathered to watch the spectacle. The invaders encountered no resistance as they exited the whaleboats, formed ranks into a Marine and a seaman regiment, and began marching toward their objectives. This initial show of force was enough to prompt the retreat of the Mexican forces led by General Gustavo Maass. In the face of this, Commodore Manuel Azueta encouraged cadets of the Veracruz Naval Academy to take up the defense of the port for themselves. Also, about 200 line soldiers of the Mexican Army remained behind to fight the invaders along with the citizens of Veracruz.
Solution:
From what USS ships did American servicemen attack Veracruz?
