 Question: can you have a heart attack from laughing Context: 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 have to be pregnant to produce milk Context: To discourage birth tourism, Australia, France, Germany, Ireland, New Zealand, South Africa, and the United Kingdom have modified their citizenship laws at different times, granting citizenship by birth only if at least one parent is a citizen of the country or a legal permanent resident who has lived in the country for several years. Germany has never granted unconditional birthright citizenship, but has traditionally used jus sanguinis, so, by giving up the requirement of at least one citizen parent, Germany has softened rather than tightened its citizenship laws; however, unlike their children born and grown up in Germany, non-EU- and non-Swiss-citizen parents born and grown up abroad usually cannot have dual citizenship themselves.
 Question: does having a baby in australia give you citizenship Context: The portion of the marginal cost curve above its intersection with the average variable cost curve is the supply curve for a firm operating in a perfectly competitive market. (the portion of the MC curve below its intersection with the AVC curve is not part of the supply curve because a firm would not operate at price below the shutdown point) This is not true for firms operating in other market structures. For example, while a monopoly ``has'' an MC curve it does not have a supply curve. In a perfectly competitive market, a supply curve shows the quantity a seller's willing and able to supply at each price -- for each price, there is a unique quantity that would be supplied. The one-to-one relationship simply is absent in the case of a monopoly. With a monopoly, there could be an infinite number of prices associated with a given quantity. It all depends on the shape and position of the demand curve and its accompanying marginal revenue curve.
