IN: Is it true that do dairy cows have to be pregnant to produce milk?

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.

IN: Is it true that can federal judges be removed by the president?

''Article III federal judges'' (as opposed to judges of some courts with special jurisdictions) serve ''during good behavior'' (often paraphrased as appointed ''for life''). Judges hold their seats until they resign, die, or are removed from office. Although the legal orthodoxy is that judges cannot be removed from office except by impeachment by the House of Representatives followed by conviction by the Senate, several legal scholars, including William Rehnquist, Saikrishna Prakash, and Steven D. Smith, have argued that the Good Behaviour Clause may, in theory, permit removal by way of a writ of scire facias filed before a federal court, without resort to impeachment.

IN: Is it true that can you cut cast iron with oxy acetylene?

Oxy-acetylene can cut only low- to medium-carbon steels and wrought iron. High-carbon steels are difficult to cut because the melting point of the slag is closer to the melting point of the parent metal, so that the slag from the cutting action does not eject as sparks but rather mixes with the clean melt near the cut. This keeps the oxygen from reaching the clean metal and burning it. In the case of cast iron, graphite between the grains and the shape of the grains themselves interfere with the cutting action of the torch. Stainless steels cannot be cut either because the material does not burn readily.
