TASK DEFINITION: In this task, you are given Wikipedia articles on a range of topics, we ask you to write a question based on the content of the articles that can be answered in a binary manner i.e. True or False.
PROBLEM: Blue moon -- One lunation (an average lunar cycle) is 29.53 days. There are about 365.24 days in a tropical year. Therefore, about 12.37 lunations (365.24 days divided by 29.53 days) occur in a tropical year. In the widely used Gregorian calendar, there are 12 months (the word month is derived from moon) in a year, and normally there is one full moon each month. Each calendar year contains roughly 11 days more than the number of days in 12 lunar cycles. The extra days accumulate, so every two or three years (seven times in the 19-year Metonic cycle), there is an extra full moon. The extra full moon necessarily falls in one of the four seasons, giving that season four full moons instead of the usual three, and, hence, a blue moon.

SOLUTION: is there a month with two full moons

PROBLEM: Dairy cattle -- To maintain lactation, a dairy cow must be bred and produce calves. Depending on market conditions, the cow may be bred with a ``dairy bull'' or a ``beef bull.'' Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as a breeding bull or sold and used for veal or beef. Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is approximately nine months. Newborn calves are removed from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf.

SOLUTION: does a cow have to give birth to produce milk

PROBLEM: Vince Carter -- On June 25, 2009, Carter was traded, along with Ryan Anderson, to the Orlando Magic in exchange for Rafer Alston, Tony Battie and Courtney Lee. Orlando hoped Carter would provide center Dwight Howard with a perimeter scorer who can create his own shot--something the Magic lacked in losing the NBA Finals to the Los Angeles Lakers. On February 8, 2010, he had a season-high 48 points, 34 in the second half, when the Magic rallied from a 17-point deficit to defeat the New Orleans Hornets 123--117. Carter helped the Magic reach the Eastern Conference Finals, where they were defeated 4--2 by the Boston Celtics. It marked his first and so far only Conference Finals series.

SOLUTION:
has vince carter ever been to the finals
