Problem: Please answer a question about the following article about Wood:
In the tree a knot is either the base of a side branch or a dormant bud. A knot (when the base of a side branch) is conical in shape (hence the roughly circular cross-section) with the inner tip at the point in stem diameter at which the plant's vascular cambium was located when the branch formed as a bud.
What shape is the knot formed by a side branch's base?
A: conical
Problem: Please answer a question about the following article about Hunting:
Unarmed fox hunting on horseback with hounds is the type of hunting most closely associated with the United Kingdom; in fact, "hunting" without qualification implies fox hunting. What in other countries is called "hunting" is called "shooting" (birds) or "stalking" (deer) in Britain. Originally a form of vermin control to protect livestock, fox hunting became a popular social activity for newly wealthy upper classes in Victorian times and a traditional rural activity for riders and foot followers alike. Similar to fox hunting in many ways is the chasing of hares with hounds. Pairs of Sight hounds (or long-dogs), such as greyhounds, may be used to pursue a hare in coursing, where the greyhounds are marked as to their skill in coursing the hare (but are not intended to actually catch it), or the hare may be pursued with scent hounds such as beagles or harriers. Other sorts of foxhounds may also be used for hunting stags (deer) or mink. Deer stalking with rifles is carried out on foot without hounds, using stealth.
What is carried out on foot without hounds?
A: Deer stalking
Problem: Please answer a question about the following article about Planck constant:
The legal process to change the definition of the kilogram is already underway, but it had been decided that no final decision would be made before the next meeting of the General Conference on Weights and Measures in 2011. (For more detailed information, see kilogram definitions.) The Planck constant is a leading contender to form the basis of the new definition, although not the only one. Possible new definitions include "the mass of a body at rest whose equivalent energy equals the energy of photons whose frequencies sum to 7050135639273999999♠135639274×1042 Hz", or simply "the kilogram is defined so that the Planck constant equals 6966662606895999999♠6.62606896×10−34 J⋅s".
The mass of a resting body with what energy would be equal to a kilogram?
A: 7050135639273999999♠135639274×1042 Hz
Problem: Please answer a question about the following article about Myanmar:
Typical jungle animals, particularly tigers and leopards, occur sparsely in Myanmar. In upper Myanmar, there are rhinoceros, wild buffalo, wild boars, deer, antelope, and elephants, which are also tamed or bred in captivity for use as work animals, particularly in the lumber industry. Smaller mammals are also numerous, ranging from gibbons and monkeys to flying foxes and tapirs. The abundance of birds is notable with over 800 species, including parrots, peafowl, pheasants, crows, herons, and paddybirds. Among reptile species there are crocodiles, geckos, cobras, Burmese pythons, and turtles. Hundreds of species of freshwater fish are wide-ranging, plentiful and are very important food sources. For a list of protected areas, see List of protected areas of Myanmar.
What industry is supported by animal labor in Burma ?
A:
the lumber industry
