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.
Q: Passage: However, the Saturn failed to take the lead. After the launch of the Nintendo 64 in 1996, sales of the Saturn and its games were sharply reduced, while the PlayStation outsold the Saturn by three-to-one in the U.S. in 1997. The 1997 release of Final Fantasy VII significantly increased the PlayStations popularity in Japan. As of August 1997, Sony controlled 47% of the console market, Nintendo 40%, and Sega only 12%. Neither price cuts nor high-profile game releases proved helpful. Reflecting decreased demand for the system, worldwide Saturn shipments during March to September 1997 declined from 2.35 million to 600,000 versus the same period in 1996; shipments in North America declined from 800,000 to 50,000. Due to the Saturns poor performance in North America, 60 of Sega of Americas 200 employees were laid off in the fall of 1997.
A:
Did Worldwide or North American shipments decrease by the largest amount?
