Problem: The Hoddle Grid (dimensions of 1 by 1⁄2 mile (1.61 by 0.80 km)) forms the centre of Melbourne's central business district. The grid's southern edge fronts onto the Yarra River. Office, commercial and public developments in the adjoining districts of Southbank and Docklands have made these redeveloped areas into extensions of the CBD in all but name. The city centre has a reputation for its historic and prominent lanes and arcades (most notably Block Place and Royal Arcade) which contain a variety of shops and cafés and are a byproduct of the city's layout.
What are the dimensions of the Hoddle Grid?
The answer is the following: 1 by 1⁄2 mile (1.61 by 0.80 km)

Problem: Seabird migration is similar in pattern to those of the waders and waterfowl. Some, such as the black guillemot Cepphus grylle and some gulls, are quite sedentary; others, such as most terns and auks breeding in the temperate northern hemisphere, move varying distances south in the northern winter. The Arctic tern Sterna paradisaea has the longest-distance migration of any bird, and sees more daylight than any other, moving from its Arctic breeding grounds to the Antarctic non-breeding areas. One Arctic tern, ringed (banded) as a chick on the Farne Islands off the British east coast, reached Melbourne, Australia in just three months from fledging, a sea journey of over 22,000 km (14,000 mi). Many tubenosed birds breed in the southern hemisphere and migrate north in the southern winter.
Where do tubenosed birds breed?
The answer is the following: the southern hemisphere
