It has an observation deck near the top from where you can see above all of Melbourne's structures. The Rialto tower, the city's second tallest, remains the tallest building in the old CBD; its observation deck for visitors has recently closed."????

input question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Pockets of Georgian architecture survived the war, but much of the city was levelled. There has been extensive redevelopment since World War II. Increasing traffic congestion in the 1920s led to partial demolition of medieval walls around the Bargate in 1932 and 1938. However a large portion of those walls remain."????
output answer: Why was the city leveled?

input question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "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 foragingkestrels 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."????
output answer: What are the number of movable eye coverings do birds have?

input question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Darwin's aims were twofold: to show that species had not been separately created, and to show that natural selection had been the chief agent of change. He knew that his readers were already familiar with the concept of transmutation of species from Vestiges, and his introduction ridicules that work as failing to provide a viable mechanism. Therefore, the first four chapters lay out his case that selection in nature, caused by the struggle for existence, is analogous to the selection of variations under domestication, and that the accumulation of adaptive variations provides a scientifically testable mechanism for evolutionary speciation."????
