You will be given a definition of a task first, then some input of the task.
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.

Passage: On May 30, 2006, SCDOT announced its preferred routing of I-73 between Myrtle Beach and Interstate 95 in South Carolina. I-73 will begin where South Carolina Highway 22 (SC 22) starts at U.S. Route 17 in South Carolina near Briarcliffe Acres, South Carolina. It will then proceed northwest crossing the proposed routing of I-74 (currently South Carolina Highway 31, the Carolina Bays Parkway). After passing Conway, South Carolina, I-73 will leave SC 22 at a new interchange to be constructed west of U.S. Route 701, and will then use a new highway to be built between SC 22 and South Carolina Highway 917 north of Cool Spring, South Carolina. I-73 will then use an upgraded SC 917 to cross the Little Pee Dee River. It will then proceed on a new freeway alignment between SC 917 and Interstate 95 in South Carolina that would have an interchange with U.S. Route 76 in South Carolina west of Mullins and then would proceed northwest to an exit with U.S. Route 501 near Latta, passing that city to the south before intersecting I-95 near South Carolina Highway 38. After crossing I-95, I-73 will use the chosen middle route, one of six potential alternative corridors that were studied all of which roughly paralleling SC 38 to proceed further north to the North Carolina state line. These alternative corridors were formally announced to the public on September 7, 2006, at a meeting in Bennettsville, South Carolina. The number of possible routes was reduced to three, and a final decision on the preferred northern route was announced on July 19, 2007. The central route caused the least disruption to homes, farms and wetlands. The North Carolina Department of Transportation and South Carolina Department of Transportation Carolina departments of transportation previously agreed to an I-73 corridor crossing the state line along SC and NC 38 near Hamlet, North Carolina, on February 11, 2005. Previously I-73 had been planned to cross the state line further west, near U.S. Route 1 in North Carolina south of Rockingham, North Carolina.
Output:
How many days after SCDOT announced its preferred routing of I-73 between Myrtle Beach and Interstate 95 in South Carolina were alternative corridors formally announced to the public at a meeting in Bennettsville, South Carolina?
