Question: Passage: 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.
Question: do dairy cows produce milk without giving birth

Answer: 0


Question: Passage: One-child policy -- The one-child policy, a part of the family planning policy, was a population planning policy of China. It was introduced in 1979 and began to be formally phased out near the end of 2015 and the beginning of 2016. The policy allowed exceptions for many groups, including ethnic minorities. Provincial governments imposed fines for violations, and the local and national governments created commissions to raise awareness and carry out registration and inspection work.
Question: does the one child policy apply to everyone in china

Answer: 0


Question: Passage: Slam Dunk Contest -- Historically, the dunk contest drew some mild criticisms. One is that players who often compete in these contests are seen as dunkers only (with the obvious exceptions of Michael Jordan, Kobe Bryant, and Julius Erving), which is why notable high flying athletes like Shawn Marion and LeBron James have sometimes refused to participate. High-profile players such as Dwyane Wade and Charles Barkley have also declined to participate citing it as an unnecessary risk to injury. In the 2000 NBA Slam Dunk Contest, Tracy McGrady injured his wrist while performing a dunk. Also in the 1995 NBA Slam Dunk Contest, Tony Dumas hurt his knee while performing his ``Texas Twister'' dunk. Although a longtime critic, LeBron James said he would perform in the 2010 Slam Dunk Contest. This decision was made after watching the 2009 dunk contest when Dwight Howard and Nate Robinson went at it. However, he withdrew his statement once the All-Star Weekend came around.
