TASK DEFINITION: In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.
PROBLEM: Passover commences on the 15th of the Hebrew month of Nisan and lasts for either seven days (in Israel and for Reform Jews and other progressive Jews around the world who adhere to the Biblical commandment) or eight days for Orthodox, Hasidic, and most Conservative Jews (in the diaspora). In Judaism, a day commences at dusk and lasts until the following dusk, thus the first day of Passover begins after dusk of the 14th of Nisan and ends at dusk of the 15th day of the month of Nisan. The rituals unique to the Passover celebrations commence with the Passover Seder when the 15th of Nisan has begun. In the Northern Hemisphere Passover takes place in spring as the Torah prescribes it: 'in the month of (the) spring' ( Exodus 23: 15). It is one of the most widely celebrated Jewish holidays.

SOLUTION: when is passover and how long is it

PROBLEM: It rises in the Blue Ridge Mountains in western McDowell County, North Carolina, approximately 20 miles (30 km) east of Asheville. It flows ENE, forming, along with the Linville River, Lake James. It then passes north of Morganton, then southeast through Lake Hickory just north of Hickory, NC, and into the Lake Norman reservoir. From Lake Norman it flows south, passing west of Charlotte, then flowing through the Mountain Island Lake and Lake Wylie reservoirs, where it forms approximately 10 miles (15 km) of the border between North Carolina and South Carolina, also the confluence of the South Fork Catawba River and Catawba River is submerged by Lake Wylie near the NC / SC state line. It flows into northern South Carolina, passing Rock Hill, then through Fishing Creek Reservoir near Great Falls, and then into the Lake Wateree reservoir, approximately 30 miles (50 km) northeast of Columbia. At the now-submerged confluence with Wateree Creek, it becomes the Wateree River.

SOLUTION: where does the catawba river start and end
