Q: 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.
Can we conclude that do cows have to have a calf to produce milk?

IN: Is it true that did the great fire of london destroy st paul's cathedral?

The cathedral was already in severe structural decline by the beginning of the 17th century. Restoration work begun by Inigo Jones in the 1620s was halted at the time of the English Civil War (1642--1651). Sir Christopher Wren was attempting another restoration in 1666 when the cathedral was destroyed in the Great Fire of London. At that point, the old structure was demolished, and the present, domed cathedral was erected on the site, with an English Baroque design by Wren.

Q: In mathematics, the irrational numbers are all the real numbers which are not rational numbers, the latter being the numbers constructed from ratios (or fractions) of integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no ''measure'' in common, that is, there is no length (''the measure''), no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself.
Can we conclude that can a irrational number be a real number?
OPTIONS:
- no
- yes
A:
yes
