Problem: Please answer a question about the following article about Poultry:
Since their domestication, a large number of breeds of chickens have been established, but with the exception of the white Leghorn, most commercial birds are of hybrid origin. In about 1800, chickens began to be kept on a larger scale, and modern high-output poultry farms were present in the United Kingdom from around 1920 and became established in the United States soon after the Second World War. By the mid-20th century, the poultry meat-producing industry was of greater importance than the egg-laying industry. Poultry breeding has produced breeds and strains to fulfil different needs; light-framed, egg-laying birds that can produce 300 eggs a year; fast-growing, fleshy birds destined for consumption at a young age, and utility birds which produce both an acceptable number of eggs and a well-fleshed carcase. Male birds are unwanted in the egg-laying industry and can often be identified as soon as they are hatch for subsequent culling. In meat breeds, these birds are sometimes castrated (often chemically) to prevent aggression. The resulting bird, called a capon, has more tender and flavorful meat, as well.
Are there any purebreed lines for poultry today?
A: with the exception of the white Leghorn, most commercial birds are of hybrid origin.
Problem: Please answer a question about the following article about Brain:
Except for a few primitive organisms such as sponges (which have no nervous system) and cnidarians (which have a nervous system consisting of a diffuse nerve net), all living multicellular animals are bilaterians, meaning animals with a bilaterally symmetric body shape (that is, left and right sides that are approximate mirror images of each other). All bilaterians are thought to have descended from a common ancestor that appeared early in the Cambrian period, 485-540 million years ago, and it has been hypothesized that this common ancestor had the shape of a simple tubeworm with a segmented body. At a schematic level, that basic worm-shape continues to be reflected in the body and nervous system architecture of all modern bilaterians, including vertebrates. The fundamental bilateral body form is a tube with a hollow gut cavity running from the mouth to the anus, and a nerve cord with an enlargement (a ganglion) for each body segment, with an especially large ganglion at the front, called the brain. The brain is small and simple in some species, such as nematode worms; in other species, including vertebrates, it is the most complex organ in the body. Some types of worms, such as leeches, also have an enlarged ganglion at the back end of the nerve cord, known as a "tail brain".
Creatures that have a diffuse nerve net are called what?
A: cnidarians
Problem: Please answer a question about the following article about 2008 Summer Olympics torch relay:
The Olympic Torch is based on traditional scrolls and uses a traditional Chinese design known as "Lucky Cloud". It is made from aluminum. It is 72 centimetres high and weighs 985 grams. The torch is designed to remain lit in 65 kilometre per hour (37 mile per hour) winds, and in rain of up to 50 millimetres (2 inches) per hour. An ignition key is used to ignite and extinguish the flame. The torch is fueled by cans of propane. Each can will light the torch for 15 minutes. It is designed by a team from Lenovo Group. The Torch is designed in reference to the traditional Chinese concept of the 5 elements that make up the entire universe.
What metal is the torch constructed from?
A: aluminum.
Problem: Please answer a question about the following article about Near East:
The Encyclopædia Britannica defines the Near East as including Armenia, Azerbaijan, Bahrain, Cyprus, Egypt, Georgia, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Libya, Oman, Palestine, Qatar, Saudi Arabia, Sudan, Syria, Turkey, the United Arab Emirates, the West Bank, and Yemen. The Food and Agriculture Organization (FAO) of the United Nations defines the region similarly, but also includes Afghanistan while excluding the countries of North Africa and the Palestinian territories. According to the National Geographic Society, the terms Near East and Middle East denote the same territories and are 'generally accepted as comprising the countries of the Arabian Peninsula, Cyprus, Egypt, Iraq, Iran, Israel, Jordan, Lebanon, Palestinian territories, Syria, and Turkey'.
The Food and Agriculture Organization of the United Nations also includes what Country in the definition of Near East?
A:
Afghanistan
