Here is a question about this article: Many birds show plumage patterns in ultraviolet that are invisible to the human eye; some birds whose sexes appear similar to the naked eye are distinguished by the presence of ultraviolet reflective patches on their feathers. Male blue tits have an ultraviolet reflective crown patch which is displayed in courtship by posturing and raising of their nape feathers. Ultraviolet light is also used in foraging—kestrels have been shown to search for prey by detecting the UV reflective urine trail marks left on the ground by rodents. The eyelids of a bird are not used in blinking. Instead the eye is lubricated by the nictitating membrane, a third eyelid that moves horizontally. The nictitating membrane also covers the eye and acts as a contact lens in many aquatic birds. The bird retina has a fan shaped blood supply system called the pecten. Most birds cannot move their eyes, although there are exceptions, such as the great cormorant. Birds with eyes on the sides of their heads have a wide visual field, while birds with eyes on the front of their heads, such as owls, have binocular vision and can estimate the depth of field. The avian ear lacks external pinnae but is covered by feathers, although in some birds, such as the Asio, Bubo and Otus owls, these feathers form tufts which resemble ears. The inner ear has a cochlea, but it is not spiral as in mammals.
What is the answer to this question: What kind of vision do owls have?

So... binocular vision


Here is a question about this article: Nanjing first became a state capital in 229 AD, when the state of Eastern Wu founded by Sun Quan during the Three Kingdoms period relocated its capital to Jianye (建業), the city extended on the basis of Jinling Yi in 211 AD. Although conquered by the Western Jin dynasty in 280, Nanjing and its neighbouring areas had been well cultivated and developed into one of the commercial, cultural and political centers of China during the rule of East Wu. This city would soon play a vital role in the following centuries.
What is the answer to this question: Who founded Eastern Wu?

So... Sun Quan


Here is a question about this article: Traditional willow growing and weaving (such as basket weaving) is not as extensive as it used to be but is still carried out on the Somerset Levels and is commemorated at the Willows and Wetlands Visitor Centre. Fragments of willow basket were found near the Glastonbury Lake Village, and it was also used in the construction of several Iron Age causeways. The willow was harvested using a traditional method of pollarding, where a tree would be cut back to the main stem. During the 1930s more than 3,600 hectares (8,900 acres) of willow were being grown commercially on the Levels. Largely due to the displacement of baskets with plastic bags and cardboard boxes, the industry has severely declined since the 1950s. By the end of the 20th century only about 140 hectares (350 acres) were grown commercially, near the villages of Burrowbridge, Westonzoyland and North Curry. The Somerset Levels is now the only area in the UK where basket willow is grown commercially.
What is the answer to this question: Where is willow growing still practiced

So...
