Q: Napa cabbage -- Napa or nappa cabbage (Brassica rapa subsp. pekinensis or Brassica rapa Pekinensis Group) is a type of Chinese cabbage originating near the Beijing region of China, and is widely used in East Asian cuisine. Since the 20th century, it is also a widespread crop in Europe, America and Australia. In much of the world, this is the vegetable referred to as ''Chinese cabbage''. In Australia it is referred to as 'wombok'.

Q: 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.

A: does a cow have to give birth to produce milk

Q: Challenger Deep -- The 2009 and 2010 maximal depths were not confirmed by the series of dives Nereus made to the bottom during an expedition in May--June 2009. The direct descent measurements by the four expeditions which have reported from the bottom, have fixed depths in a narrow range from 10,916 m (Trieste) to 10,911 m (Kaiko), to 10,902 m (Nereus) to 10,898 m (Deepsea Challenger) Although an attempt was made to correlate locations, it could not be absolutely certain that Nereus (or the other descents) reached exactly the same points found to be maximally deep by the sonar/echo sounders of previous mapping expeditions, even though one of these echo soundings was made by Nereus' mothership.

A:
has anyone reached the bottom of challenger deep
