Context: The NBA high school draftees are players who have been drafted to the National Basketball Association (NBA) straight out of high school without playing basketball at the collegiate level. The process of jumping directly from high school to the professional level is also known as going prep-to-pro. Since 2006, the practice of drafting high school players has been prohibited by the new collective bargaining agreement, which requires that players who entered the draft be 19 years of age and at least one year removed from high school. Contrary to popular belief, the player does not have to play at least a year in college basketball, as the player can choose to instead play in another professional league (like the NBA G League or especially somewhere overseas) like Brandon Jennings or Emmanuel Mudiay in Italy and China respectively, simply take the year off, such as the case with Mitchell Robinson, or even hold themselves back a year in high school before declaring for the draft, like with Satnam Singh Bhamara or Thon Maker.
 Question: does the nba draft out of high school Context: The .300 AAC Blackout (designated as the 300 BLK by the SAAMI and 300 AAC Blackout by the C.I.P.), also known as 7.62×35mm is a carbine cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. Its purpose is to achieve ballistics similar to the 7.62×39mm Soviet cartridge in an AR-15 while using standard AR-15 magazines at their normal capacity. It can be seen as a SAAMI-certified copy of J.D. Jones' wildcat .300 Whisper. Care should be taken not to use 300 BLK ammunition in a rifle chambered for 7.62×40mm Wilson Tactical.
 Question: is there a difference between 300 blackout and 300 aac blackout Context: 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.
