PROBLEM: Phase 10 -- Phase 10 is a card game created in 1982 by Kenneth Johnson and sold by Mattel, which purchased the rights from Fundex Games in 2010. Phase 10 is based on a variant of rummy known as Liverpool Rummy, and is a member (along with Liverpool) of the contract rummy family. It requires a special deck or two regular decks of cards; it can be played by two to six people. The game is named after ten phases (or melds) that a player must advance through in order to win. Phase 10 was Fundex's best selling product, selling over 32,600,000 units to date, making it the 2nd best-selling commercial card game behind Mattel's Uno. In December 2010, Fundex sold the rights to Phase 10 to Mattel, and now develops and markets a line of games based on brands and other IP formerly exclusive to Mattel as well as Fundex's own brands.

SOLUTION: can you play phase 10 with 8 players

PROBLEM: Dairy cattle -- The dairy cow will produce large amounts of milk in its lifetime. Production levels peak at around 40 to 60 days after calving. Production declines steadily afterwards until milking is stopped at about 10 months. The cow is ``dried off'' for about sixty days before calving again. Within a 12 to 14-month inter-calving cycle, the milking period is about 305 days or 10 months long. Among many variables, certain breeds produce more milk than others within a range of around 6,800 to 17,000 kg (15,000 to 37,500 lbs) of milk per year. The Holstein Friesian is the main breed of dairy cattle in Australia, and said to have the ``world's highest'' productivity, at 10000L of milk per year. The average for a single dairy cow in the US in 2007 was 9164.4 kg (20,204 lbs) per year, excluding milk consumed by her calves, whereas the same average value for a single cow in Israel was reported in the Philippine press to be 12,240 kg in 2009. High production cows are more difficult to breed at a two-year interval. Many farms take the view that 24 or even 36 month cycles are more appropriate for this type of cow.

SOLUTION:
does a dairy cow need to be pregnant to produce milk
