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.
Input: Passage: Ozawa's "Northern Force" comprised four aircraft carriers, two World War I battleships partially converted to carriers , three light cruisers , and nine destroyers. His force had only 108 aircraft. (That is slightly more than maximum capacity of the flagship Zuikaku. Ozawa's force was not located until 16:40 on 24 October, largely because Sherman's TG38.3which was the northernmost of Halsey's groupswas responsible for searches in this sector. The force that Halsey was taking north with himthree groups of Mitscher's TF38was overwhelmingly stronger than the Japanese Northern Force. Between them, these groups had five large fleet carriers , five light carriers , six modern battleships , eight cruisers , and more than 40 destroyers. The air groups of the ten U.S. carriers present contained 600-1,000 aircraft. At 02:40 on 25 October, Halsey detached TF34, built around the 3rd Fleet's six battleships and commanded by Vice Admiral Willis "Ching" Lee. As dawn approached, the ships of Task Force 34 drew ahead of the carrier groups. Halsey intended Mitscher to make air strikes followed by the heavy gunfire of Lee's battleships.
Output:
How many aircraft carriers did Halsey have?
